SAR ECCM and Imaging Based on Non-uniform PRI

SAR,ECCM, non-uniform sample

Non-uniform pulse repetition interval (PRI) provides radar system strong electronic counter-countermeasures (ECCM) ability under electronic countermeasure (ECM) environment. For synthetic aperture radar (SAR) system, the effectiveness caused by non-uniform pulse repetition interval (PRI) on SAR imaging and deception jamming has not yet been illustrated comprehensively. And like the other radar systems, the non-uniformly sampled SAR data should not be processed in the traditional way. Analysis of imaging, countermeasures resistance and reconstruction algorithm for non-uniform PRI SAR data is discussed in this paper.
