Abstract: A radar warning receiver is disclosed. The radar warning receiver includes an antenna, a signal detection unit, a signal identification unit and an alarm. The antenna collects radio frequency (RF) signals. The signal detection unit is configured to generate a group of frequency and amplitude signals based on the collected RF signals. Specifically, the signal detection unit includes a pair of limiting amplifiers for converting the collected RF signals into corresponding pulsed output signals that track the actual frequency oscillations of the collected RF signals, and a pseudo-random noise generator for injecting noise into one of the limiting amplifiers. Based on the frequency and amplitude signals, the signal identification unit determines whether or not any of the collected RF signals includes a threat signal. The alarm is utilized to present a threat signal to a human operator.

Abstract: The system can utilize a standard high speed FPGA interface for a non-traditional use to facilitate the processing of high amounts of streaming digital data or the method can be implemented in other high speed data transfer systems. This system and method include the use of training/calibration pattern techniques implemented in a FPGA, or other system, to calibrate numerous multi-arm demultiplexers. The training/calibration sequence data rate being slower than the input data rate. In one example, the system and method utilized a mono-bit receiver capable of digitizing signals of at least 40 GHz with at least 20 GHz of instantaneous bandwidth.
