Research on the Evaluation Method of Smoke Jamming Effect

Abstract

Smoke is one of the important jamming methods for infrared imaging terminal guidance weapon, but how to evaluate the jamming effect of smoke is not well solved. Based on the whole process of infrared imaging guidance system, this paper viewed the jamming effect as the evaluation of the search stage and the tracking stage. Aiming at the evaluation of searching stage, the probability model of infrared imaging target detection is designed, and the evaluation criterion and method of the jamming effect of the smoke are given. In view of the evaluation of tracking stage, a total of three evaluation methods are designed, which are the contrast characteristics, correlation characteristics and fractal characteristics. The evaluation criterion and method of the jamming effect of smoke on photoelectric imaging tracking system are given, and finally the jamming effect evaluation software is designed and developed. The simulation results show that the evaluation method of smoke jamming effect for infrared imaging detection and tracking system is effective.
