Frequency agility MIMO-SAR imaging and anti-deception jamming performance

Imaging proceduce for frequency agility multiple-input multiple-output synthetic aperture radar (MIMO-SAR) in presence of deception jamming is proposed, where the radar, at each pulse repetition interval (PRI), emits a waveform by one antenna, and the transmitted baseband signals are modulated with step carrier frequencies in successive PRIs. System model and signal model of both target echo and jamming were analyzed. Imaging procedure flow of frequency agility MIMO-SAR was expounded, a signal recombination technique was presented, enables the MIMO-SAR to achieve high resolution imagery. Frequency agility MIMO-SAR imaging in deception jamming scenarios was simulated at the end. Experiment results are used to show the validity of the introduced concepts.
