A novel space target location method for spaceborne radar

Combined with the space target observation radar application requirements, related issues of spaceborne MMW (MilliMeter Wave) InISAR (Interferometric Inverse Synthetic Aperture Radar) are researched. A proposed system contains an L-shaped orthogonal observation structure is designed and analyzed basing on a spaceborne platform. The location of a space target can be acquired using imaging and interferometry, and the interferometric phase wrapping is solved by sub-band dual frequency conjugated processing (DFCP). The two-stage space target location method and the spaceborne radar system are presented. Finally, a simulation is designed and proven to be a feasible solution by the simulation experiment which also indicated the direction of the following research work.
