【摘要】：干涉合成孔徑雷達(dá)(InSAR)測(cè)量技術(shù)通過對(duì)同一地區(qū)的兩景影像進(jìn)行干涉分析獲取高精度的地形信息。由于InSAR具備高精度定量分析定位能力,國內(nèi)外已經(jīng)發(fā)展了諸多星載和機(jī)載InSAR設(shè)備用于地形測(cè)繪,其中最著名的包括SRTM系統(tǒng)以及TanDEM-X任務(wù)。文中以SRTM和TanDEM-X為例,介紹了InSAR在地形測(cè)繪中的主要參數(shù)以及應(yīng)用情況,為國產(chǎn)InSAR衛(wèi)星的指標(biāo)設(shè)計(jì)提供了一定的參考。
[Abstract]:Interferometric synthetic Aperture Radar (InSAR) measurement technology obtains high precision terrain information by interferometric analysis of two scene images in the same area. Because InSAR has the ability of high precision quantitative analysis and positioning, many satellite and airborne InSAR equipment have been developed for topographic mapping at home and abroad, the most famous of which include SRTM system and TanDEM-X mission. Taking SRTM and TanDEM-X as examples, this paper introduces the main parameters and application of InSAR in topographic surveying and mapping, which provides a certain reference for the index design of domestic InSAR satellite.
