摘要: 针对激光交会雷达作为在空间交会对接过程中的相对导航敏感器,研究了未来特殊背景下,非合作目标航天器对雷达信号发射干扰的情况下的相对导航滤波算法。针对高维模型计算量大的特点对传统粒子滤波算法进行了改进,并与扩展卡尔曼滤波器进行了仿真比较,仿真结果表明改进后的粒子滤波器的滤波效果远远优于扩展卡尔曼滤波器,且计算量优于传统粒子滤波。

Abstract: Considering laser radar as the relative navigation sensor during space rendezvous and docking, and special situation in the future, a relative navigation filter algorithm with non-cooperative target eradiating against radar signal is investigated. Considering large calculation mount with high-dimension model, traditional particle filter algorithm is improved, and compared with EKF through simulation. The simulation result shows that the filtering effect of improved particle filter is much better than the EKF, and the calculation mount is largely reduced compared with traditional particle filter.
