FM radars represent one of the oldest and simplest–yet at the same time one of the most versatile types of radar. The paper presents a tutorial review of the basic principles of FM radars and introduces a number of new ideas, including digital generation of wideband linear FM waveforms, and aperture synthesis with FM radar.

Wigner distribution and FM radar signal design
IEE Proceedings F Radar and Signal Processing, 1989The Wigner distribution is a bilinear distribution originally developed in the field of quantum mechanics. It has recently attracted considerable attention as a time-frequency distribution for use in signal processing. The properties of the Wigner distribution are reviewed and its relationship to other distributions, in particular the ambiguity ...

A Precise New System of FM Radar
Proceedings of the IRE, 1956The paper describes a new system of fm radar by which both the range and the speed of the target can be accurately measured. The "fixed error," which is a characteristic of fm radar apparatus now in use, has been eliminated, affording correct measurement of ranges, even if they are very short.

Alternative “Bases” for Gradient-Based Optimization of Parameterized FM Radar Waveforms
International Radar Conference, 2023Even for a fixed time-bandwidth product there are infinite possible spectrally-shaped random FM (RFM) waveforms one could generate due to their being phase-continuous.

On the Recycling of Random FM Radar Waveforms
Radar, 2023Random frequency modulated (RFM) waveforms have been found to possess a number of useful radar properties such as high dimensionality, good spectral containment, and amenability to high-power transmitters.

Designing Random FM Radar Waveforms with Compact Spectrum
IEEE International Conference on Acoustics, Speech, and Signal Processing, 2021Spectrally-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.
