Radar seeker performance evaluation based on information fusion method

摘要

Radar seeker is responsible for transmitting the dynamic position information of the target back to the weapon controlcenter in the guidance phase. It is of great engineering significance to evaluate the anti-jamming ability of radar seekerin the anti-jamming environment Aimed at obtaining more reasonable evaluation result, an evaluation method basedon information fusion is proposed against the background of angle measurement performance in this paper. Radarseeker performance test have many stages with different characteristics. Information fusion has advantages in radarperformance evaluation which takes advantage of measured data obtained in different stages rather than process themrespectively. Furthermore, we studied two specific issues in the information-fusion stage. The first problem is aboutconsistency testing between different information using K-L information distance measurement, which is the premiseof information fusion. The second problem is about the information weights calculation by PLT criterion, which can takesample size into account. Information fusion can make full use of the multi-source test information to obtain more reliableevaluation conclusion. Experimental results prove the effectiveness of the proposed method.
