內容簡介

　　艦船尾跡是真實海場景中不可缺失的部分，是識別艦船目標的類型、位置、航速和航向信息等特征的重要途徑。本書共8 章，詳細闡述了Kelvin 尾跡、含湍流遠場綜合尾跡、泡沫流尾跡、近場尾跡、內波尾跡和水下運動目標尾跡的幾何建模、電磁散射建模和合成孔徑雷達（SAR）成像仿真技術；結合計算流體力學（CFD）仿真技術和電磁散射的調制譜優(yōu)化面元模型，將仿真模型應用于艦船尾跡的SAR 圖像特征檢測、基于尾跡的艦船目標參數反演和浮標目標隱蔽優(yōu)化設計工程中。本書構建了一套基于艦船尾跡流場的電磁散射特性分析和雷達圖像仿真的系統(tǒng)理論和應用方法，使讀者能夠通過本書的學習掌握運動艦船尾跡的電磁散射機理和成像仿真方法，靈活解決實際工程問題。本書適合從事雷達設計與評估、微波遙感、雷達目標與環(huán)境特性、電磁成像算法與圖像理解的相關科研工作人員閱讀，也可作為高等學校相關專業(yè)研究生的教學參考用書。
