| 摘 要： | 基于捷联惯导/反辐射导引头组合抗目标雷达关机制导方案,研究了UKF方法在对目标雷达被动定位中的应用.针对反辐射导引头测角存在非线性特性的特点,提出了一种基于扩展状态变量维数的方法同时实现目标状态估计和导引头非线性特性补偿.仿真结果表明,UKF方法与传统的EKF方法相比具有更高的定位精度.

| Abstract: | Based on guidance scheme of antagonism against the radar stopping radiating using strap-down inertial navigation system and anti-radar seeker,the application of UKF to passive localization of target is studied.Considering nonlinear characteristic of anti-radar seeker,a method of extending dimensions of state variables is present to achieve estimation of target's state and compensation of nonlinear characteristic of anti-radar seeker.The result of simulation shows that passive localization using UKF is more ... |
