摘　　要：介绍了利用紧缩场与喇叭天线配合使用进行双站二维成像测量的方法。给出用于此测试方法的成像算法——抛物面反投影法。并分别采用线性反投影、球面反投影和抛物面反投影处理点阵目标的仿真数据,比较三种成像方法的差异。按该方法构成实验系统,对几个典型目标进行双站成像测试,验证了方法的有效性。同时对比单站成像的结果,考察目标双站成像所体现的散射特性。The bistatic 2-D imaging measurement is presented, which is applied in a Compact range with a horn antenna as the receive antenna. The imaging processing algorithm named Paraboloid Back-Project is given, which cooperates with the measurement. Respectively, the simulated scattering data of array was processed by the Linear Back-Projection, the Spherical Back- Projection and the Paraboloid Back-Projection. The result difference among them was concerned. The experimental system according to the measurement was constructed and some typical targets were determined in the system. The effectivity of the measurement was verified. Compared with the monostatic imaging result, the bistatic scattering characteristics of the targets were studied.
