摘要
小均方 (LMS)自适应时延估计法不依赖于输入信号和噪声的统计先验知识而可以跟踪动态或时变的环境和参数 ,算法亦比较简单。计算机仿真和湖试数据分析表明 ,将LMS自适应时延估计法应用于被动定位系统 ,可以获得较高的定位精度。另外 ,对影响被动定位精度的因素进行了分析。
LMS adaptive time delay estimation method doesnt rely on the prior knowledge concerning the statistical characteristics of the received signals,and can be used to trace dynamic or time varying environment and parameters.Besides,the algorithm is simple and easy to realize.The computer simulation results and lake test data analysis indicate that LMSTDE method can ensure high estimation precision when it is used in passive positioning system.
