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 …

In this paper we discuss the relationship between cognitive radar and waveform diversity.
The cognitive decision-making process selects the most appropriate waveform from 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 …

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 …

With the increasing demand for access to the radio frequency spectrum, there has been an
emergence of spectrum sharing radar systems. Along with this comes the need for rapid …

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 …

Pulse-agile radar systems have demonstrated favorable performance in dynamic
electromagnetic scenarios. However, the use of non-identical waveforms within a radar's …

A cognitive radar (CR) system can offer enhanced target tracking performance due to its
intelligence on the perception‐action cycle, wherein a CR adaptively allocates the limited …

In this article, we develop a new waveform codesign approach for radar–communications
spectral coexistence using a decision-theoretic framework called partially observable …
