弹道目标一次性小扰动辨识与轨迹滤波方法

Discrimination and Trajectory Estimation of Ballistic Target with One-Off Small Disturbance

针对弹头末修和释放诱饵带来的小扰动,提出了基于高精度多普勒测速的修正残差扰动检测方法,显著降低了虚警概率和漏检概率。针对扰动特点,提出了采用增加状态变量和衰减记忆滤波的自由段弹道估计改进算法,仿真验证了扰动后轨迹滤波的有效性。

An amendatory innovation detection method of disturbance based on high precision Doppler velocity measurement which can reduce the probability of false alarm and the probability of miss is developed to detect small disturbance in the course of correcting trajectory terminally or releasing decoy of warhead. An amendatory trajectory estimation of free phase with increasing state variable and fading memory filtering is also developed and is verified by computer simulation.
