UWB SAR低信雜比環(huán)境下時(shí)頻表示成像方法研究

UWB SAR Time-Frequency Representation Image Formation in Low Signal-to-Clutter Ratio Environment

  • 摘要: 超寬帶合成孔徑雷達(dá)(UWB SAR)為了探測(cè)隱藏在樹林中或埋于地下的目標(biāo),通常工作在低信雜比的環(huán)境中。目標(biāo)淹沒在強(qiáng)烈的雜波背景之中很難被發(fā)現(xiàn)。該文利用時(shí)頻表示成像(TFRIF)方法得到不同方位空間頻率對(duì)應(yīng)的一組SAR圖像,并且分辨率幾乎沒有損失。通過(guò)這組SAR圖像的融合能夠提高信雜比。利用實(shí)際數(shù)據(jù)驗(yàn)證了該文方法的有效性。
