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 …

With the reality of increasing radio frequency (RF) spectral congestion, radar systems
capable of dynamic spectrum sharing are needed. Recent work has demonstrated a real …

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 …

Designing radar waveforms with notched spectral regions can mitigate mutual interference
with other proximate RF users. However, this capability comes at the cost of degraded range …

Ultrawideband (UWB)-throb signal has the potentials and many applications for high-
resolution radar. In this paper, an optimization algorithm for spectral notching and …

This short descriptive paper provides a sense of the recent state of radiofrequency (RF)
electromagnetic (EM) spectrum research and development (R&D), applications …

Radar receivers must be extremely sensitive to detect faint target signatures. To this end
pulse-Doppler processing of pulse compression waveforms integrates faint target echoes …

In a congested radio spectrum, radar systems must be capable of sharing spectrum in real
time. Two possible radar transmission approaches involve either avoiding interferers or …

Various classes of random FM waveforms have recently emerged that are amenable for high-
power radar transmitters while providing high dimensionality that facilitates a variety of new …

Random FM (RFM) waveforms have recently been demonstrated to achieve desirable
power spectrum characteristics commensurate with low pulse compression sidelobes …
