| 摘 要： | 为了克服ＬＭＳ自适应时延估计（ＬＭＳＴＤＥ）算法计算量大的问题，引进遗传算法进行ＬＭＳＴＤＥ的寻优规划，并采取了克服过早收敛的措施。对超声信号进行时延估计的实验表明，该方法大大减少了计算量，并有较高的时延估计精度。

| Abstract: | To cut down the amount of computation of LMSTDE method, Genetic algorithms with special measures to overcome immature constringency is employed for optimazing search process of the LMSTDE. The experimental results of Ultrasonic ranging system show that.while keeping high TDE precision, this method can greatly reduce computation amount. |
