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 transmitters, which tend to introduce significant distortion to other waveform cla

A special class of noise radar that conforms to a frequency modulated (FM) structure has experienced a surge in practical applications in recent years. This article provides a historical context for these random FM waveforms, examines their useful at

Spectrally-shaped random FM (RFM) waveforms have recently been shown to greatly expand radar design freedom, provide good spectral containment, and are amenable to physical implementation in high-power transmitters. A key design factor involves ways

Random FM radar waveforms designed to possess a desirable spectral shape (on average) have been experimentally demonstrated for an increasing number of applications. However, the benefits of these waveforms can be offset by the computational cost of

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-time cognitive capability on a software defined radio (SDR) by generating pulse

The use of waveforms possessing constant envelope and good spectral containment, combined with high-fidelity arbitrary waveform generation (AWG) capability, has been shown to minimize transmitter distortion effects when waveform diversity is needed.
