The backscattering coefficients,which of different surface object in radar image and same surface object in radar image of different polarization,differ quietly from each other,which have relation with the structural characteristics of themselves.
本文采用ENVISAT ASAR的APMode(Alternating Polarisation Mode)数据,由雷达图像成像原理及物理机制入手分析广州市几种典型地物(水体、植被、建筑物)在不同极化方式下后向散射特征及其成因。
Meanwhile,use different interpolar distance as a joint section to determine the dip,dip angle and downdip extension of the water storage structure,and placing of wells.
同时采用不同极距作联合剖面确定蓄水构造的倾向、倾角和延深,并依此布置水井位置,找水效果显著。
