A Filtering Algorithm for Strong Maneuvering Target Based on Adaptive Grid Mechanism

Abstract

In this paper, a filtering algorithm for tracking strong maneuvering targets is proposed to improve the attack ability of air-to-air missiles in air combat. Firstly, by analyzing the filtering algorithm of strong maneuvering targets, a hybrid grid multiple model(HGMM)framework based on interacting multiple model algorithm is constructed. Then, the hybrid grid multiple model algorithm is designed in detail. Finally, numerical simulation shows that the proposed method is feasible and has good tracking effect, the tracking accuracy is improved abaut 20%.
