Study on evaluation methods of ISAR jamming effect is to be an important research problem in electronic countermeasures (ECM). Up to now there is no generally accepted progress and objective criterion published. In this paper, on the basis of studying the image model of ISAR point target used the most classical range-Doppler(R-D) algorithm, equivalent jamming-to-signal ratio (EJSR) is utilized, and...
Some methods used to evaluate jamming effects on conventional radar are unsuitable to ISAR because of their particularity. In this paper, the cross entropy theory is utilized to evaluate the jamming effect on ISAR. We investigated the cross entropy and presented the concept of symmetry cross entropy (SCE) to compensate for its shortage, and then theoretically proved that it was a distance measure;...
