In this paper, the ground moving target indication based on modified along-track interferometry of spaceborne parasitic radar system is analyzed. The imaging simulation of a piece of fluctuant terrain with a moving target verifies the validity. The appropriate formation fling parameters are presented when considering some performance metrics, such as the blind velocity, the minimum detectable velocity and the velocity precision. Some conclusions are serviceable of orbital design. Finally, GMTI performance of two typical systems, Cartwheel and Pendulum, is analyzed through computer simulation.
