Abrégé
The system and method generates a pulse or a signal that is transmitted between a central processing unit or processor and an Ethernet integrated circuit card to program a trigger generator in the IC. The pulse is effectively a 1PPS signal that is provided to the IC, which may be in the form a field programmable gate array to enable timing synchronization. The trigger in the IC may also generates an interrupt to the processor so a driver in the CPU is instructed to set the next trigger. For the trigger to be accurately controlled, the control routine is implemented in the driver existing in kernel space rather than user space. A routine or protocol periodically polls the interrupt to determine when the trigger must be reset.

Abrégé
The disclosed method enables efficient registration and correction of random vertical and horizontal offsets of a plurality of images of a feature to enable combination thereof with maximum noise suppression. The method includes obtaining image cross correlations and estimating correlation peaks. If a correlation peak cannot be uniquely determined for a given correlation, all candidates are retained. An improved robust weighted regression is applied thereto to obtain estimates of the image shifts. Dimensional symmetry is exploited to remove redundancy from the weighted normal equation, and computational requirements are further reduced by analytically determining the coefficients matrix and the inhomogeneous matrix, thereby circumventing conventional computations. Solution of the resulting consistent, full rank, linear system requires only matrix inversion. For N images, the present method thereby increases computation speed and reduces storage by approximately N2.

A hybrid RADAR and communication system provides both RADAR and wireless communication (COMMS) that share the same antenna, transmit and receive amplifiers, and other hardware, thereby reducing size, weight, and power requirements. In embodiments, COMMS implementation only requires adding additional software to a RADAR system. Embodiments are EW/COMMS systems that provide electronic warfare and wireless communication. EW/COMMS embodiments facilitate communication in hostile environments by enabling data exchange at any frequency within a broad EW frequency range. Communication signals can be obfuscated by interleaving them with EW waveforms at the same RF frequency. Collaborative communication between EW systems is enhanced by reducing EW communication lag times. Systems with physically distinct broadband and narrow band receivers can negotiate data exchange timing and frequencies by exchanging low power, low data rate control signals that are detected by the broadband receiver, while subsequent high density data bursts are received by the narrowband receiver.

A method of determining a schedule for a pointing device includes distributing targets among a plurality of groups and assigning schedules to the groups, after which the groups and group schedules are not modified. A partial pointing schedule is successively grown by selecting a list of remaining groups, and appending a best candidate sub-schedule for the list to the partial schedule. If a sub-schedule cannot be found for which the grown partial schedule meets all applicable requirements, the partial schedule is pruned to a previous state and a different, previously evaluated sub-schedule is appended to the pruned partial schedule to attempt re-growth. Groups, group schedules, lists, and sub-schedules can be selected according to values, dwell times, and/or windows of performance of the targets, groups, and sub-schedules. If no schedule is found that meets all requirements, a missed group can be excluded from the schedule.

Techniques are disclosed for determining a true bearing angle from an airborne platform to a source of a radar signal. In an embodiment, a grid is generated based on a coarse range to, and angle-of-arrival of, an electromagnetic signal. The grid represents a geographic area thought to contain the emission source. A measured spatial angle is computed for each pulse of the signal received during a data collection interval. Hypothesized spatial angles are computed for a point in each grid box in the grid. A score is generated for each grid point based on the computed hypothesized spatial angles for the grid point and the measured spatial angles. The grid point having the lowest score is identified as a seed location and is used to launch a Nelder-Mead algorithm that converges on a point in the grid. A true bearing angle to the source of a radar angle is computed to the point provided by the Nelder-Mead algorithm.

The system and method for chromatic correlation interferometry direction finding (CIDF) used to resolve ambiguities. Ambiguities are overcome by correlating over a range of frequencies. In some cases, multiple (i.e., 2 or more) frequencies or a continuous range of frequencies are used to make a more robust correlation manifold. As the complex response manifold is frequency dependent, using a set of two or more manifolds provides a significant reduction of false peaks.

Abrégé
An asynchronous medium access control layer scheduler increases efficiency for directional mesh networks by removing extra overhead in the time slots. The efficiency is increased by dividing time slots into sub-slots to allow for a receiving node to be offset by at least one sub-slot from the transmitting node. This enables the scheduler to more efficiently schedule operations for the nodes so that nodes can be performing other functions rather than waiting to receive a transmission or waiting after transmitting a transmission. The sub-slots may be sized to approximate the transmission propagation time or time of flight delay.

Techniques for reducing a likelihood of detection of an imaging system by another imaging system are provided. For example, the techniques may include controlling read-out such that the timings between frames of an image are non-uniform. For example, a processor may be configured to generate a plurality of frame synchronization signals from a main clock and transmit the plurality of frame synchronization signals to readout circuitry. Each frame synchronization signal is an instruction to start the biasing and reading for a respective frame. The plurality of frame synchronization signals may be generated such that a timing between pulse biasing the same thermal sensor is not uniform. The techniques may also include controlling the read-out such that the timings between lines within a frame are non-uniform which also results in the timing between pulse biasing of the same thermal sensor not being uniform.

A Deep-Learning (DL) explainable AI system for Radio Frequency (RF) machine learning applications with expert driven neural explainability of input signals combines three algorithms (A1, A2, and A3). A1 is a neural network that learns to classify spectrograms. During training, A1 learns to map a spectrogram to its paired label. It outputs a label estimate from a spectrogram. Labels account for device number and spectrum utilization. The neural network is built on two-dimensional dilated causal convolutions to account for frequency and time dimensions of spectrogram data. A2 is a user-defined function that converts an input spectrogram into a vector that quantifies human-identifiable elements of the spectrogram. A3 is a random forest feature extraction algorithm. It takes as input the outputs of A2 and A1. From these, A3 learns which elements in the vector output by A2 were most important for choosing the labels output from A1.

A system and method for reducing laser communication terminal pointing uncertainty. The method trains an artificial neural network (ANN) with input data characterizing terminal pointing error and dependent parameters. The method inputs the trained ANN a set of data of these dependent parameters with unknown pointing error. The method uses the ANN output to apply corrections to the terminal pointing solution to reduce pointing uncertainty. The method can condition the ANN generated corrections to avoid cases where application of the ANN correction could exceed the original pointing uncertainty. This conditioning includes computing the Euclidean distance between current ANN input parameter values and values in the ANN training dataset, and bounding the allowed magnitude of the ANN pointing correction. The method can train the ANN incrementally during terminal operation for real-time updates or train the ANN offline with gathered data and implement the trained ANN on the terminal for subsequent links.

Abrégé
A mid-wave infrared (MWIR) discrete zoom lens for use with remote surveillance and identification having a dual focal length of 9 and 6.39 inches and F #2.8 and F #2, respectively. In one case, a full field of view is about 30.8 degrees for a 9 inch focal length configuration and about 43 degrees for a 6.39 inch focal length configuration. The lens is corrected for monochromatic and chromatic aberrations over the wavelength range 5100 nm-3300 nm. The focal plane may constitute a pixel array consisting of MWIR sensitive material (e.g. InSb, HgCdTe, nBn, SLS, etc.) for use in high-resolution, wide-area imaging applications.

Abrégé
An antenna module configured for use on an underwater vehicle is disclosed. The antenna module includes an array of spiral antennas fabricated on a multi-layer substrate that provides wide-band RF communication with direction finding (DF) capability. The antenna module can also include other antennas fabricated on the same multi-layer substrate, such as one or more global positioning system (GPS) receivers, an ultra-high frequency/very-high frequency (UHV/VHF) antenna, or one or more iridium antennas. The antenna module may further include a water-proof housing that is coupled to the outside hull of an undersea vehicle via a coupling mechanism. The coupling mechanism allows the antenna module to rotate between a stowed position against the hull and a deployed position that extends the antennas out away from the undersea vehicle. The antenna module is curved or flexible so it can stow against a corresponding curved hull of the undersea vehicle.

Abrégé
Techniques are provided for laser illumination employing closely spaced laser beams. A system implementing the techniques according to an embodiment includes a semi-cylindrical optical block comprising a curved surface and a planar surface. A first laser source to generate a first laser beam directed to the planar surface, wherein the first laser beam enters the optical block at a first angle that exceeds a critical angle, relative to the planar surface, the critical angle causing total internal reflection, such that the first laser beam is refracted through and exits the optical block. A second laser source to generate a second laser beam directed to the curved surface, wherein the second laser beam enters the optical block at a second angle that exceeds the critical angle, relative to the planar surface, such that the second laser beam is reflected off the planar surface and exits the optical block parallel to the first laser beam exiting from the optical block, the separation based on a location of the entry of the first laser beam into the optical block. The separation of the exiting first and second laser beams is controlled by the selected translation distance.

Abrégé
A laser system produces pulses having wavelengths between 2000 nm and 2100 nm, peak output powers greater than 1 kW, average powers greater than 10 W, pulse widths variable from 0.5 to 10 nsec, pulse repetition frequencies variable from 0.1 to over 2 MHz, and a pulse extinction of at least 60 dB. Pulses from a diode laser having a wavelength between 1000 nm and 1100 nm are amplified by at least one fiberoptic amplifier and applied as the pump input to an Optical Parametric Amplifier (OPA). A cw laser provides an OPA seed input at a wavelength between 2000 nm and 2200 nm. The idler output of the OPA having difference frequency wavelength between 2000 nm and 2100 nm is further amplified by a crystal amplifier. The fiberoptic amplifier can include Ytterbium-doped fiberoptic. The crystal amplifier can include a Ho:YAG, Ho:YLF, Ho:LuAG, and/or a Ho:Lu2O3 crystal.
