Weight empowerment method in information fusion for radar-seeker performance evaluation

Abstract

With the continuous development of radar terminal guidance technology, the evaluation of the performance of a radar seeker has become a very necessary and important system subject. Rationally allocating the index weight has always been an important spot in the research of performance evaluation. For this problem, a new method based on importance level to allocate the index weights is proposed, which can both reflect the subjective opinion of an expert and the objective facts. Second, rather than evaluate radar seeker performance in simulation test and outfield experiment, respectively, information fusion is applied to evaluate the radar performance instead of serial-phased scheme which takes advantage of both infield simulated and outfield measured data. Furthermore, a model was proposed to calculate the weights of each information element in the information-fusion stage. Considering that the performance evaluation of a radar seeker involves many experimental stages, information fusion which can make full use of the multi-source test information can help to obtain more accurate and reliable evaluation conclusion. Both the theoretical analysis and experimental results prove the effectiveness and efficiency of the proposed method.
