| 摘 要： | 为提高多站无源协同跟踪的精度.提出了一种基于方位时差的目标跟踪方法.从一种拟线性的方位增量卡尔曼预处理方法人手,降低方位观测的误差,利用距离和时差跟踪建立观测方程.使用扩展卡尔曼滤波的方法对目标的运动状态进行估计,并采用分布式估计集中处理的方式融合多站并行估计数据.通过计算机仿真分析了该方位时差方法的跟踪性能.仿真结果表明.该方法对于目标状态的估计与真值偏差较小,能够满足跟踪精度要求.

| Abstract: | To improve the cooperative passive tracking accuracy in multiple stations,a scheme of target tracking based on DOA and TDOA is proposed.A pseudo linear bearing preprocessing method based on Kalman is used to reduce the bearings measurement errors.The measurement equation is established according to the range and TDOA,and the target movement states are estimated by EKF.The multiple estimated data are fused by means of the distributed estimation and centralized processing. Using the proposed scheme,the tracki... |
