| 摘 要： | 实现固定单站对运动辐射源无源定位,传统的方法是测量TOA和DOA。本文将方位角变化率测量信息也引入该定位问题,提出了基于MGEKF(修正增益扩展卡尔曼滤波),对三维运动辐射源的无源定位跟踪算法。通过推导伪线性测量方程,本文进行了测量TOA和DOA对三维运动目标无源定位的可观测性分析。最后给出了计算机仿真结果。

| Abstract: | To realize passive location and tracking for moving emitters with a single non-moving observer, TOA and DOA measurements are utilized traditionally. In this paper, the azimuth angle changing rate measurement is introduced into this passive location problem and a location algorithm for 3-D moving emitters based on MGEKF is given. Furthermore, the observability conditions are analyzed using the pseudo-measurement equations. Finally, the computer simulation results are presented. |
