Evaluation Method of Jamming Effect on ISAR Based on the Similarity of Features

By weighing the similarity of features before and after jamming, a novel evaluation method of jamming effect on ISAR based on the similarity of features is presented in the paper. This method can reflect the impact on the target features caused by jamming, consequently, the jamming effect can be evaluated by the similarity of features. It can not only be computed easily, but also has the merit of unitary. Furthermore, Two typical noise barrage jamming modes, radio frequency (RF) noise jamming and noise frequency modulation (FM) jamming are employed in computer simulation of interference with ISAR, The results indicate the validity and feasibility of the proposed method.
