We investigate three emerging topics essential for the development of cognitive radar (CR)
for spectrum sharing: the response time (RT) of the CR, the autonomous regulation of the …

Recent work demonstrated closed-loop results for a real-time cognitive sense-and-notch
radar capability via software-defined radio (SDR). The subsequent software-defined radar …

Random frequency and pulse repetition interval agile (RFPA) signals have excellent anti-
jamming ability and achieve low probability of intercept (LPI), making them promising for …

Leveraging a recent method for spectrally-shaped random FM (RFM) waveform generation,
in conjunction with a particular implementation of spread-spectrum signaling, a multi-user …

Coherently processed waveforms with irregular pulse repetition frequency (PRF) for radar
applications have the potential to simultaneously resolve periodic range and Doppler …

Efficient clutter filtering for pulsed radar systems remains an open issue when employing
pulse-to-pulse modulation and irregular pulse interval waveforms within the coherent …

This short descriptive paper provides a sense of the recent state of radiofrequency (RF)
