Abrégé

An ordnance includes a nose cone configured to be attached to a fuze or a warhead. The nose cone, when attached or coupled to the fuze or warhead, covers the fuze and at least a portion of the warhead to provide the ordnance with an aerodynamic profile. The nose cone has a shape that improves the aerodynamic profile of the ordnance as compared to ordnance that does not include a cover over the fuze. The improved aerodynamic profile enables the ordnance to achieve a greater range (approximately 20% or more) than ordnance that does not have a separate nose cone covering the fuze.

The system and method of swarm navigation using a follow the forward approach. Using on-board sensors and communications links between members of a swarm, numerous targets can be engaged more quickly and precisely. In some cases, a designator is used to help a forward of the swarm navigate to a target using image -based navigation up until terminal guidance is used. A cascade of messages are projected back to a following round so that each member of a swarm can determine a best target/round match and provide real-time, up-to-date information regarding targets' locations and each round's location, range to target, target selection, and the like.

Abrégé

The system and method of a dual mode semi active laser seeker and imaging system using pulse detection and angle determination as applied to quad detectors to properly identify a correct designator spot. The angle performance is driven by the field of view of the imaging system. The imaging system resolution provides the required angle accuracy for guidance as cued by pulse detection apertures. The imaging system eliminates the need to designate until impact thus eliminating exposure to counter fire against the designator. The elimination of designation until impact also opens up the opportunity rapid engagement of multiple targets from a single designator.

Techniques are disclosed for filtering a radio frequency (RF) signal using an A-path bandstop filter with an extended, spurious-free upper passband. In an embodiment, a bandstop filter includes a bank of three switched capacitors in series with the RF signal path through the filter, in contrast to 4- or 8-capacitor banks or other bandstop filters where A is a power of 2. In this 3 -path example configuration, an undesirable spurious bandstop notch at the 3rd and 5th harmonics of the clock frequency are eliminated or substantially reduced, improving performance of the filter in the desired passbands while preserving the notch in the desired stopband at high RF signal frequencies. Another A-path bandstop filter embodiment includes a bridged T-coil circuit, which absorbs a shunt capacitance of the bandstop filter into the bridged T-coil circuit.

Abrégé

A laser communication architecture provides precise optical alignment between terminals without requiring dedicated beacon lasers or dedicated beacon wavelength optics. Instead, the same lasers and optics are used for both alignment and communication. A beacon modulation is applied to alignment beacons transmitted at or near communication wavelengths so as to differentiate them from communication beams. The beacon modulation can include phase and/or amplitude variation of a high frequency modulation, and/or "ping-pong" toggling of the beacon wavelength. In some full duplex red/blue embodiments, ping-pong modulation is implemented by alternated red/blue tuning of the transmit laser or by switching between separate red and blue transmit lasers, for example using a 2x1 laser switch, while maintaining constant beacon amplitude, thereby avoiding optical amplifier dynamic response issues. During communication, embodiments maintain optical alignment by diverting a percentage of received communication light to the tracking sensor.

Abrégé

A phase locked loop (PLL) control system includes a voltage-controlled oscillator (VCO) circuit including an inductor and a plurality of capacitors arranged in parallel with the inductor. Digitally enabling or disabling the capacitors in a thermometer coded manner via switches creates tuning states that provide additional frequency range, and each has a limited range of VCO frequency tuning. Slowly ramping the switched capacitance, by implementing the capacitor as a varactor, from one thermal code to the next, provides a wider continuous VCO frequency tuning range for use in the PLL. The slow transition between tuning states allows the PLL to remain in lock, useful under changing operating conditions. Specifically, under changing operating conditions, digital logic detects the PLL tuning control voltage approaching the edge of a VCO band and will add/reduce VCO capacitance effectively transitioning into the adjacent VCO band while the PLL maintains lock via its normal feedback loop.

A transmit laser module includes separate "red" and "blue" linear polarized lasers, or a single linear polarized laser tunable from red to blue. The transmit/receive diplexer uses a linear polarized beam splitter and a waveplate to transition the output beam between left and right circular polarization without affecting precision pointing, or co-boresight transmit/receive alignment. Waveplate polarization can be switched by physical rotation, or electrically using a liquid crystal variable retarder (LCVR). Red and blue bandpass filters can be selected in the receiver and/or transmitter by physical manipulation, optical switches, DWDM 3-port filters, and/or LCVRs.

Abrégé

A digital or smart array antenna has at least one radio and a processor coupled to each antenna element. The processor is coupled with programmable logic that demodulates a plurality of signals received at one antenna element to obtain demodulation symbols. After obtaining the demodulation symbols, the programmable logic applies a weighting function. In this order or sequence, the digital array antenna is able to reduce the processing requirements associating within the signal information. The reduced processing requirements enable the signal information to be shared with adjacent antenna elements that may be timing adjusted between adjacent elements. Then, the sharing continues across all elements the array until the signal reaches an edge of the array. At the edge of the array, a signal beam may be generated that is steer in response to the processed signal information shared between all the elements in the array.
