| 摘 要： | 地形对精确的ScanSAR辐射定标来说是个不容忽视的因素。目前，有关地形因素对条带模式SAR辐射特性的影响已做过大量研究，文中针对ScanSAR模式的特点，研究地形对ScanSAR辐射特性的影响，包括地形对散射面积效应的影响以及地形对scalloping效应和波束边界现象的影响，并对其进行了定量分析。

| Abstract: | Terrain is very important to ScanSAR radiometric calibration. Presenuy, many statues have been done about the effect of terrain on strip mode SAR radiometric property. In this paper the effect of terrain on ScanSAR radiometric property is studied, including the effect of terrain on ground true backscattering area, scalloping and beam boundary. Quantitative analysis on the effect of terrain has also been done. |

| Keywords: | terrain ScanSAR radiometric error Doppler centroid |
