%X Based on Fractional Fourier Transform (FrFT) and clutter suppression interferometer techniques, a method of detecting slow-moving ground targets with Geosynchronous Earth Orbit (GEO) spaceborne-airborne bistatic three-aperture Synthetic Aperture Radar (SAR) is presented. Firstly, based on the characteristic of GEO spaceborne-airborne bistatic SAR, the DPCA condition of clutter suppression is derived. Then from the spatial geometry model and echo signal of the system, the theory of moving target focusing, clutter suppression, moving target detection and parameter estimation is derived in detail. Finally, computer simulation results validate its effectiveness.
