| 摘 要： | 以星载寄生式SAR系统成像信号模型为基础,详细分析了这一新系统的干涉性能和空间分辨能力,给出了 各自的限制条件。分析了两者限制的本质一致性,并统一以基线形式表示出来,同时提出了距离向有效基线和方位向有效 基线的新概念。最后以Cartwheel编队构形进行了实例分析,特别指出了基线耦合、多基线对性能的影响。

| Abstract: | Based on radar image model of spaceborne parasitic SAR system, The characteristics and abilities of INSAR and spatial resolution improvement on this new system are analyzed in detail, limits are each given. The limits of these two applications are proven to be coincident and are given uniformly in forms of baseline. The concepts of range and azimuth effective baseline are given at the same time. Capability and limitation of Interferometric Cartwheel are analyzed as an example, the influence of interrelation between range and azimuth baseline and multi-baselines are pointed out. |
