N2 - This paper addresses the issue of moving target detection and velocity estimation in the Geosynchronous Synthetic Aperture Radar (GEO SAR) scenario, this problem has not been handled yet despite the promising potential of GEO SAR systems in the global monitoring domain. New expressions for the Doppler centroid and the Doppler rate that take into account the specific features of a geosynchronous orbit are developed. Moreover, a new Ground Moving Target Indication (GMTI) technique was proposed, it makes use of the aforementioned expressions combined with the use of the Non Uniform Cubic Phase Function (NUCPF) algorithm to estimate the moving target motion parameters. Simulation results are carried out to demonstrate the accuracy of the developed expressions and the effectiveness of the proposed GEO SAR GMTI technique.
