摘要
用图象重建的方法研究运动物体的双基地雷达成象．在改进模型的基础上，把成象归结为解析函数的外推和函数沿一簇椭圆曲线Ｒａｄｏｎ变换的反演，阐明了运动距离和物体可完全成象的关系，给出了唯一性定理．
This paper investigates some imaging problems of bistatic radar of moving objects. Radar imaging is the imaging reconstruction of scattering distributive function of an object. In some cases, it can be interpreted as the inverse of Radon transform along a class of elliptic curves. By inverstigating the relation between moved distance and objects completely imaging, uniqueness theorems are obtained.
