  • 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。
    Abstract: Since Interferometric Circular SAR (InCSAR) has the advantage of all-directional observation, a method for Digital Elevation Model (DEM) extraction based on InCSAR is proposed to ensure the high accuracy of the high resolution Circular SAR imaging. Firstly, the signal model of InCSAR is presented when Back Projection (BP) processing is adopted for SAR imaging; secondly, DEM extraction based on InCSAR is proposed; thirdly, the proposed method is validated by the simulation test.
