从物体散射场对应的傅里叶空间出发，提出基于空间谱域分布的成像系统定性评价体系。运用该体系对探地雷达、合成孔径雷达多站雷达系统进行成像分析，并根据空间谱域分布结果给出了相关雷达的数据采集优化方案。有关工作的推广将为多基地雷达系统和星载雷达的编队飞行方案提供理论基础和指南。

From the Fourier space K corresponding to the scattering field of the object, an imaging evaluation mechanism based on the spatial spectral coverage is proposed. The evaluation system is used to analyze the GPR, SAR with muhistatic data acquisition, and then the optimization of related radar data collection is obtained by the spatial spectral coverage results. The gen- eralization of the work will provide theoretical foundation and guiding for the multistatic radar system and formation flying of space based radar.
