Abstract :
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; thereby, a new evaluation model was found that used SCE as an evaluation index. In the end, two typical noise blanket jamming modes, RF noise jamming and FM noise jamming, are employed in computer simulation of interference with ISAR, and the SCE was used to quantitatively evaluate jamming effect. The result shows that the method proposed is effective and feasible.
