Abstract

The geostationary orbit is the most significant orbit. Space objects in the orbit could be detected by imaging nearby using spaceborne inverse synthetic aperture radar (ISAR). Based on the analysis of RCS characteristic of geostationary orbital targets, the orbital altitude and revisiting period of space-based radar are designed in detail, so are the antenna's size. The relationship between image's resolutions of spaceborne ISAR and system parameters is discussed. Finally, the accumulated time according to appointed cross range resolution is proposed both in direct orbit and retrograde orbit. The research work is meaningful as a guide to engineering realization.
