Nonlinear Radar for Finding RF Electronics: System Design and Recent Advancements. Abstract: An extensive review of nonlinear radar systems is performed. …Conventional radars commonly use a linear frequency-modulated (LFM) waveform as the transmitted signal. The LFM radar is a simple system, but its impulse-response function produces a −13.25 dB sidelobe, which in turn can make the detection of weak targets difficult by drowning out adjacent weak target information with the sidelobe of a strong target. To overcome this challenge, this paper ...The principle-of-operation of nonlinear radar is summarized and applications for this technology are listed. Targets addressed by this type of radar follow a power-series model, and from this model a nonlinear radar range equation is derived.

Nonlinear radar exploits the difference in frequency between radar waves that illuminate and are reflected from electromagnetically nonlinear targets. Harmonic radar is a special type of nonlinear radar that transmits one or multiple frequencies and listens for frequencies at or near their harmonics. Oct 26, 2022 · Synthetic aperture radar (SAR) systems have the capacity for day-and-night and all-weather surveillance, which has become increasingly indispensable for military surveillance and global comprehensive environmental monitoring. With the development of the high-resolution SAR imaging technique, studies on SAR jamming have also received much interest. Traditional jamming methods are based on ...
The radar range equation for detecting targets using linear radar has been defined and derived many times for many different applications. The nonlinear radar range equation has been defined in the literature but a step by step derivation is lacking and no experimental validation has been shown. In the context of nonlinear radar, no more harmonic may be reflected from the target. Furthermore, additional increases in power beyond the saturation point may cause other nonlinearities to activate, which reduce the harmonic reflected from the target.Pages 1 - 44 Abstract This chapter is devoted to a comprehensive introduction of the nonlinear dynamic ocean. In fact, it is key to understanding the mechanism of synthetic aperture radar (SAR) for imaging ocean dynamics.
