前言

通過獲取運動目標的距離信息，並利用這些隨時間變化的距離序列來實時估計目標運動參數的技術，稱為純距離目標運動分析（Range-only TargetMotion Analysis，RTMA）。隨著無線傳感器網絡的不斷發展，純距離目標運動分析在艦艇雷達組網定位、聲吶浮標搜潛、艦炮射擊協同式檢靶等領域中得到越來越廣泛的應用。由於純距離繫統本質上的強非線性以及受到應用領域中觀測條件的限制，因此，關於純距離繫統的可觀測條件、目標定位與跟蹤算法、單站機動航路優化、靜止多站站址布局優化的理論研究成果很少，尚未形成完整的體繫。本書內容正是基於此背景展開的，將純距離目標運動分析劃分為單觀測站和多觀測站問題，開展繫統可觀測性、目標定位與跟蹤算法、單站機動航路優化、靜止多站站址布局優化的研究，豐富了這一領域的理論研究成果，同時圍繞純距離繫統在水下聲學傳感器中的應用進行了論述。
本書由10 章組成，主要內容如下：
第1 章為緒論。介紹了純距離目標運動分析的概念、研究現狀、研究熱
點及本書的組織結構。
第2 章研究了單站純距離繫統的可觀測性問題。建立單站純距離繫統的數學模型，給出了可觀測性定義，分析觀測站與目標在不同運動規律下的可觀測性條件。通過獲取運動目標的距離信息，並利用這些隨時間變化的距離序列來實時估計目標運動參數的技術，稱為純距離目標運動分析（Range-only TargetMotion Analysis，RTMA）。隨著無線傳感器網絡的不斷發展，純距離目標運動分析在艦艇雷達組網定位、聲吶浮標搜潛、艦炮射擊協同式檢靶等領域中得到越來越廣泛的應用。由於純距離繫統本質上的強非線性以及受到應用領域中觀測條件的限制，因此，關於純距離繫統的可觀測條件、目標定位與跟蹤算法、單站機動航路優化、靜止多站站址布局優化的理論研究成果很少，尚未形成完整的體繫。本書內容正是基於此背景展開的，將純距離目標運動分析劃分為單觀測站和多觀測站問題，開展繫統可觀測性、目標定位與跟蹤算法、單站機動航路優化、靜止多站站址布局優化的研究，豐富了這一領域的理論研究成果，同時圍繞純距離繫統在水下聲學傳感器中的應用進行了論述。
