摘要
用全极化SAR对地观测中,倾斜地表的同极化回波极大值对应入射波极化的取向角。基于迁移,通过两次飞行SAR图像,确定地面点的水平和垂直方向,建立数学模型,对开采沉陷进行分析预计,保证地表建(筑)筑物的安全。
In surface surveying by polar metric SAR, polarization preference angle of incident wave which is the biggest value of polarization reflection wave corresponds to inclination surface. Based on transformation, horizontal direction and vertical direction are determined by two times flying SAR images, builts up the mathematics model analysis and prediction are carried out in mining subsidence, so the safety of the surface is pledged.
