摘要: 针对空中作机动飞行的点目标,利用弹载被动系统(包括红外被动系统和被动雷达系统)测量的目标光谱辐射照度信息,建立了具有Markovk跳变参数的统一目标距离估计模型。基于结构随机跳变系统最优滤波理论,提出了一种被动系统距离估计算法,考虑到系统的实时性要求,推导了其简化算法。仿真结果验证了算法的正确性,并且简化算法具有很高的实时性。

Abstract: Aiming at maneuvering point targets flying in the sky,a uniform missile-borne passive system(include infrared passive system and passive radar system) distance estimation model with Markov jump parameters is built by using the spectra radiation illuminance of the targets.Based on the optimal filtering theory of structure stochastic jump systems,a passive system distance estimation algorithm is presented.In view of the rapidity of the algorithm,two simplified calculations are derived.The computer simulation verifies the validity of the algorithms, and the simplified algorithm is high real-time.
