艦船尾跡是真實(shí)海場(chǎng)景中不可缺失的部分，是識(shí)別艦船目標(biāo)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(xì)闡述了Kelvin 尾跡、含湍流遠(yuǎn)場(chǎng)綜合尾跡、泡沫流尾跡、近場(chǎng)尾跡、內(nèi)波尾跡和水下運(yùn)動(dòng)目標(biāo)尾跡的幾何建模、電磁散射建模和合成孔徑雷達(dá)（SAR）成像仿真技術(shù)；結(jié)合計(jì)算流體力學(xué)（CFD）仿真技術(shù)和電磁散射的調(diào)制譜優(yōu)化面元模型，將仿真模型應(yīng)用于艦船尾跡的SAR 圖像特征檢測(cè)、基于尾跡的艦船目標(biāo)參數(shù)反演和浮標(biāo)目標(biāo)隱蔽優(yōu)化設(shè)計(jì)工程中。本書構(gòu)建了一套基于艦船尾跡流場(chǎng)的電磁散射特性分析和雷達(dá)圖像仿真的系統(tǒng)理論和應(yīng)用方法，使讀者能夠通過本書的學(xué)習(xí)掌握運(yùn)動(dòng)艦船尾跡的電磁散射機(jī)理和成像仿真方法，靈活解決實(shí)際工程問題。 本書適合從事雷達(dá)設(shè)計(jì)與評(píng)估、微波遙感、雷達(dá)目標(biāo)與環(huán)境特性、電磁成像算法與圖像理解的相關(guān)科研工作人員閱讀，也可作為高等學(xué)校相關(guān)專業(yè)研究生的教學(xué)參考用書。
