During the rapid development of synthetic aperture radar (SAR), jamming techniques against SAR have aroused intensive study interests in the field of electronic counter measures (ECM). In this paper, we compare the jammer's transmitter power required by coherent deceptive jamming against SAR and by incoherent noise jamming against SAR. It is pointed out that, in order to yield same jamming-to-signal...
This paper focuses on the two-dimensional (2D) high-resolution image reconstruction with wideband V-style frequency modulation (V-FM) signals, where the range compression of the received signals is achieved by the dual-channel dechirping and the azimuth compression is done via the traditional Fourier transform (FT). The superiority of V-FM signals are two folds: 1) The system ambiguity appeared in...
Raw signal simulators for synthetic aperture radar (SAR) in different acquisition modes have been studied individually. This letter is dedicated to presenting a method for simulating multimode SAR raw signal in a unified framework. To this end, we first simulate stripmap SAR raw signal, and then mutate the raw signal from stripmap mode into the desired acquisition mode. The acquisition mode mutation...
