未知波形信號(hào)的多徑時(shí)延估計(jì)新方法

A New Algorithm for Multipath Time Delay Estimation of Unknown Signal

  • 摘要: 該文提出了一種從單個(gè)陣元接收數(shù)據(jù)中估計(jì)未知波形信號(hào)多徑回波時(shí)延的新方法。該方法通過建立單陣元接收數(shù)據(jù)的頻域信號(hào)模型,分析得出了利用該模型估計(jì)多徑時(shí)延與利用陣列估計(jì)來波方向問題的相似性。進(jìn)而,估計(jì)來波方向的ESPRIT算法被改造用于估計(jì)多徑時(shí)延。文中還對(duì)通過信號(hào)模型估值存在的模糊問題進(jìn)行了分析,并提出了解決辦法。仿真實(shí)驗(yàn)結(jié)果證明了新方法的有效性。
