Abstract
Embodiments of the present invention provide for the detection/identification of objects near a rotary-wing/VTOL aircraft such as a helicopter, drone, or an eVTOL (electric Vertical Take Off & Landing) aircraft using LiDAR. Various aspects of the present invention may include installation of one or more LiDAR devices on a mast of a rotor system of a rotary-wing/VTOL aircraft. The LiDAR device(s) may be pointing outward from the central axis of the mast and may be aligned to avoid interference form the rotor blades. Multiple LiDAR devices may be oriented/pointed above, below or in-plane with the rotor system. As the mast rotates, the LiDAR is pulsed providing a range to objects near the rotor system as the LiDAR emitted beams are scanned through the 360 degree rotation of the rotor mast. A processor determines whether objects detected within the detection envelope/volume represent a threat or hazard condition to the aircraft.

Abstract
An adaptive interrogation method is provided, the method including determining application of an adaptive whisper shout interrogation sequence. The determination may be predictive and based on an anticipation of garbled replies or may be reactive and based on a plurality of replies to an initial ATCRBS interrogation, there being interference between the replies such that the replies are unable to be properly decoded. The adaptive whisper shout interrogation sequence includes adapting a subsequent ATCRBS interrogation. The adaptation may be a change in an amplitude difference between an interrogation pulse and a suppression pulse of the subsequent ATCRBS interrogation (i.e. a bin width), as compared to the initial ATCRBS interrogation; or the adaptation may be a change in a power of the subsequent ATCRBS interrogation as compared to the initial ATCRBS interrogation. The subsequent ATCRBS interrogation is then transmitted, and one or more replies are received.

Abstract
A distributed antenna system of an aircraft includes first and second antennas and corresponding first and second remote transceiver units (RTUs). Each RTU receives a radio signal from the corresponding antenna and includes a field-programmable gate array (FPGA)/digital signal processor (DSP). The FPGA/DSP of a second RTU receives a second signal corresponding to the radio signal from the second antenna and receives a first signal from the first RTU corresponding to the radio signal from the first antenna. The FPGA/DSP of a second RTU determines which of the first and second antennae will transmit a reply to an interrogation included in the radio signals from the first and second antennae, based on a comparison of the first signal and the second signal.

A method can include determining, by an avionics system, a hazard condition with respect to an ownship aircraft. The method can also include generating, by the avionics system, a maneuver inhibition based on the determined hazard condition. The method can further include providing the maneuver inhibition to a traffic avoidance or alerting system.
Various avionics systems may be enhanced by methods and systems for bearing reception. For example, a traffic alert and collision avoidance system, or other surveillance system, can be provided with a system or configured for a method of improved bearing reception. For example, a method can include performing traffic alert and collision avoidance surveillance of a target aircraft using an interrogation over a bottom antenna of an own aircraft. The method can also include enhancing determination of a bearing of the surveillance by obtaining a bearing of the target aircraft using an alternative to making a bearing determination based on signal characteristics of a reply to the interrogation.

Abstract
Systems and methods for providing antenna calibration can be used in a variety of applications. A method of calibrating an antenna array for use in a traffic advisory system or traffic alert and collision avoidance system provide a mechanism that renders complex combining circuitry unnecessary in the array. A method can include receiving an unsolicited reply that contains absolute position information of an intruder aircraft. The method can also include determining a bearing of a signal encoding the reply based on a phase relationship of the signals from an antenna array not configured to operate with an internal self-test phase calibration mechanism. The method can further include comparing the bearing based on the phase relationship with a bearing calculated by a comparison of the absolute positions of a host aircraft and the intruder aircraft. The method can additionally include calibrating the antenna array based on the result of the comparison.

Abstract
Systems and methods are delineated in which dynamic thresholds may be employed to detect and provide alerts for potential conflicts between a vehicle and another vehicle, an object or a person in an aircraft environment. Current systems for airport conflict detection and alerting consider one or more alerting boundaries which are independent of the amount of traffic present at any one time or over the course of time. Because nuisance alerts rates depend to a large extent on the amount of traffic, and because alert detection thresholds are often set based on a desire to limit nuisance alerts to a specific threshold, adapting those thresholds based on, among other things, the amount of traffic can result in earlier alerting in some crash scenarios and can even result in providing an alert in a crash scenario where no alert would have otherwise been generated.

Abstract
There are presented various approaches to monitor performance of RF systems and circuitry such as those used in aircraft transponders. Such monitoring may be designed to verify operational performance of transponders as set forth by FAA regulations, or may be used to periodically or continually monitor integrity of transponder performance. Data may be collected by such periodic or continual monitoring, and may be analyzed to identify potentially troublesome trends in transponder performance, allowing early intervention or repair, if warranted.

Abstract
A method according to the present invention includes transmitting a Mode S interrogation and receiving a response from an aircraft that has received the Mode S interrogation. A range to the aircraft is determined based on a time period between transmitting the Mode S interrogation and receiving the response. The method further includes receiving information from one or more data sources and determining at least one of a bearing to the aircraft and a position of the aircraft using the determined range and the information from the one or more data sources. Information can be received from any number (or type) of data sources, such as ADS-B-equipped aircraft.

Abstract
Measurements of frequency and/or phase are taken at the signal ports (S1-S4) of an ISS device (10). These measurements are used to determine phase errors within the ISS device, and phase errors due to the antenna cables (C1-C4). On port, (e.g., S1) is selected as the reference port and then, based on these determined phase errors, offsetting phase errors are determined to correct the phase for the other ports (e.g., S2, S3, S4) with respect to the reference port. The signals at the antenna ports (A1- A4) are then in phase when an omnidirectional antenna pattern is desired from the TCAS antenna array (16). One in embodiment the frequency of the calibration signal is fixed; in another embodiment two different, fixed frequencies are used; and in still another embodiment the frequency is swept to achieve a predetermined measured phase difference.

Piesinger, Gregory, H.
Abstract
A TCAS receiver includes an antenna, an analog to digital converter (ADC), and a FPGA. The antenna receives an ADS-B squitter signal. The ADC converts the signal to digital signal. The FPGA uses matched filters for matching at least a portion of the digital signal to a message, thereby increasing ADS-B squitter sensitivity.
