內(nèi)容簡介

　　陣列信號處理是現(xiàn)代聲納設備的核心功能之一。通過接收陣列的信號處理，可以獲取空間指向性增益，提高空間分辨和干擾抑制能力，實現(xiàn)對目標的檢測與跟蹤、方位與距離估計；通過發(fā)射陣列的信號處理，可以獲取具有一定時延差或相位差的陣元信號，從而形成指向性發(fā)射波束，提高聲源級；通過空-時自適應處理，可以提高對弱目標的檢測能力。近年來，聲納技術不斷發(fā)展，出現(xiàn)了多線列陣聲納、連續(xù)波聲納、MIMO聲納等新體制聲納以及自適應盲處理、時反處理、矢量信號處理、魯棒性波束形成、?；盘柼幚淼刃滦吞幚硭惴?，這些都是聲納陣列信號處理的發(fā)展與豐富。本書深入、系統(tǒng)地介紹了可應用于實際聲納設備的陣列信號處理技術，在簡單的原理接收基礎上又大量的計算機模擬仿真及湖、海試實際數(shù)據(jù)的處理結果。另外本書有較大篇幅的聲納陣列信號處理領域的新技術介紹。
