內容提要

陣列信號處理是現代聲納設備的核心功能之一。通過接收陣列的信號處理，可以獲取空間指嚮性增益，提高空間分辨和乾擾抑製能力，實現對目標的檢測與跟蹤、方位與距離估計；通過發射陣列的信號處理，可以獲取具有時延差或相位差的陣元信號，從而形成指嚮性發射波束，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，聲納技術不斷發展，齣現瞭多綫列陣聲納、連續波聲納、MIMO聲納等新體製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、模基信號處理等新型處理算法，這些都是聲納陣列信號處理的發展與豐富。本書深入、係統地介紹瞭可應用於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、海試實際數據的處理結果。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。
