【摘要】 简单介绍机载合成孔径雷达用双天线干涉法测高得到三维SAR成像的原理并给出了实例。实例中选用英国Andover飞机在C波段获得的Malvern山的三维立体像和美国NASA/JPL设计的AIR-SAR/TOPSAR三波段干涉测高在C波段测得的玻利维亚Andes山的立体像。文中指出,航天飞机只给出了单天线双航过测高的实例。而干涉法有时会出现相位折叠,必须解开。文中给出了相位解开的参考文献。更多还原

【Abstract】 This paper describes the principle of airborne interferometric synthetic aperture radar using two antenna to get three dimensional image and gives some examples.In England,the aircraft Andover using its C band SAR gets reconstructed topographic map of the Malvern Hill.In the United States of America,AIRSAR/TOPSAR at C band gets topographic map of the Andes Hill.Until now space aircraft only provides topographic map by using one-antenna double pass technique.Phase folding appears sometimes for interferometric SAR,which must be unwrapped.Some reference papers about the phase unwrapping techniques are given.更多还原
