Abstract: A system and method for detection and identification of an Unmanned Aircraft Systems (UAS) employs a radar system to detect and identify the UAS based on the rich Doppler spectrum generated by one or more rotors and associated motors onboard the UAS. UAS have a low radar cross sections (RCS), relatively low speed, and possess a unique Doppler signature providing data for the system to discriminate once the system detects the quadcopter UAS. The system and method functions as a traditional radar, yet analyzes the micro-Doppler signature, including the RCS and radial speed, to detect and identify the UAS. Based on the signature analysis, the system and method are able to distinguish one model from other types of UAS.

Abstract: A system and method onboard an aircraft generates pilot awareness of obstacle clearance during an engine out (EO) go around (GA) situation. The system herein receives inputs from either a pilot selection or aircraft state change indicating a GA below a published missed approach altitude and also receives an input from an engine status monitor indicating an EO situation. As a GA below the published missed approach altitude does not ensure obstacle clearance with an EO, the systems herein generate a pseudo engine out go around procedure (PEOGAP) which calculates a minimum climb gradient maintaining a minimum separation from all obstacles within an area bound by the published missed approach. Once generated, the systems herein display the PEOGAP to the pilot for adequate obstacle separation and pilot awareness.

Abstract: Lossless digital cancelation of internally generated spurious products within a signal receiver system is provided. In embodiments, the receiver system generates reference frequencies corresponding to internal components within the receiver (e.g., mixers, oscillators, clocks, analog-digital converters (ADC)) that introduce spurious products into the digitization of a received RF signal. The receiver system precisely duplicates each introduced spurious product based on the reference frequencies and filters out each corresponding spurious product out of the digitized signal. Individualized canceler circuits for each introduced spurious product adjust the corresponding duplicate spurious products to cancel out the introduced spurious product from the digitized signal, resulting in an output signal free of self-generated interference.
