| 摘 要： | 由于短基线时差无源定位受到辐射源目标到达时间测量精度和多站间定位精度的影响,使得短基线时差无源定位精度比长基线情况要差。本文研究了短基线时差无源定位的滤波算法,推导了时差定位的推广Kalman滤波算法公式。仿真结果表明,该算法可有效提高短基线情况下的时差无源定位精度。

| Abstract: | Influenced by the measurement accuracy of the TOA of radiator targets and the mutual location accuracy for multi-stations,the accuracy of passive TOA location with short baselines is lower than that with long baselines.In this paper,the filtering algorithm of passive TOA location with short baselines is studied,and the EKF algorithm formula is deduced.The simulation result shows that this algorithm can effectively improve the accuracy of passive TOA location with short baselines. |
