DEM Extraction Based on Interferometric Circular SAR

  • 摘要: 圓跡干涉SAR具有對(duì)場(chǎng)景目標(biāo)進(jìn)行全方位觀測(cè)測(cè)量的優(yōu)勢(shì),為了滿足高分辨率圓跡SAR成像對(duì)高精度的場(chǎng)景數(shù)字高程模型(Digital Elevation Model, DEM)的需求,該文提出了一種基于圓跡干涉SAR數(shù)據(jù)的高程估計(jì)方法。首先推導(dǎo)了采用后向投影(Back Projection, BP)算法時(shí)的圓跡干涉SAR信號(hào)模型,然后給出了基于圓跡干涉SAR處理的場(chǎng)景DEM提取流程,最后通過(guò)仿真實(shí)驗(yàn)驗(yàn)證了所提方法的有效性。
