摘要: 首先针对目前大部分时延估计算法的估计精度受采样时间间隔限制,提出了一种基于超分辨分析方法的时延估计方法。当通道数大于2个时为多值优化问题,采用改进遗传算法实现了多通道时延估计。仿真实验验证了该方法的有效性,且其估计精度不直接受采样时间间隔的影响,非均匀搜索能够获得很好的估计性能。

Abstract: In present time delay estimate methods,the precisions are confined by sampling distance.A method based on the high-resolution methods in array signal processing is supported in this paper.While channel number is more than 2,it can use advanced genetic algorithm to solve the problem.According to the result of experiments,this method doesn’t confine by the sampling distance directly.It can achieve excellent estimation capability.
