In this paper, we discuss the state of radio frequency (RF) coexistence and how it benefits
from dynamic spectrum sensing. We categorize coexistence of radar and communications in …

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 …

While a number of signal structures have been proposed for radar, frequency modulation
(FM) remains the most common in practice because it is well-suited to high-power …

A metacognitive radar switches between two modes of cognition—one mode to achieve a
high-quality estimate of targets, and the other mode to hide its utility function (plan). To …

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 …

Threats and security are critical issues in a multi-RADAR environment, which severely affect
the performance metrics of a RADAR system, such as range resolution, false detection, and …

We consider the intersection between nonrepeating random FM (RFM) waveforms and
practical forms of optimal mismatched filtering (MMF). Specifically, the spectrally-shaped …

In this paper we examine some of the practical aspects of implementing cognitive radar (CR)
techniques onto software defined radar (SDRadar) platforms. These aspects include: 1) the …

The class of noise radar waveform known as random frequency modulation (RFM) has been
used to enable a variety of new sensing capabilities. It was also recently shown in simulation …

A microwave photonic (MWP) radar system with improved signal-to-noise ratio (SNR)
performance is proposed and experimentally demonstrated. By improving the SNR of …
