摘要:
針對冰下噪聲的顯著脈沖特征及其對冰下的探測聲吶的干擾的問題,本文采用第8次北極科考聲學實驗和松花江實驗獲得的冰下噪聲數據,研究其統計特性及對匹配濾波器檢測性能的影響。分析了冰下噪聲數據的統計特性,采用Alpha穩定分布作為統計模型,通過分數低階矩法估計噪聲數據獲得的Alpha穩定分布參數并對噪聲數據進行擬合并同高斯分布擬合情況進行對比,采用蒙特卡羅(Monte-Carlo)方法,利用實際冰下噪聲數據及仿真數據分析匹配濾波檢測性能,結果表明:冰下噪聲具有非高斯性,拖尾較重;相比高斯分布,Alpha穩定分布更符合實際冰下噪聲統計特性;相同信噪比下,寬帶脈沖信號抑制冰下脈沖噪聲性能優于窄帶脈沖信號,并且不同特征指數α對檢測性能有一定的影響。本文的研究結果可為在冰下工作的主動聲吶設計及性能預報提供一定的理論依據。
