摘　　要：根据接收雷达接收到的信号能量,建立了被动雷达距离估计模型,提出了一种基于结构随机跳变系统最优滤波理论的距离估计算法,实现了被动雷达对目标的距离测量。同时考虑算法的实时性和快速性,在精度允许的情况下,对估计算法进行了适当的简化,推导了两种简化算法,以满足不同条件下的工程需要。仿真结果表明3种算法都能准确地估计接收雷达和目标间的距离。Based on signal energy received by receiving radar, we built up a distance estimation model, propesed a new algorithm for distance estimation based on structure stochastic jump optimal filter theory, and realized distance estimation of passive radar. Considering the real-time requirement of the algorithm, we made appropriate simplification to the estimation algorithm, and obtained two simplified algorithms for satisfying the engineering requirements under different conditions in allowable precision scope. Simulation results indicated that the three algorithms can all estimate accurately the distance between the receiving radar and the target.
