Research on Design and Control of Spaceborne Multistatic Radar System

Using three satellites to compose two bistatic radar system, realizes two surveys to target in a sector cycle. Through using the satellite orbit dynamics characteristic, orbital altitude, eccentricity, inclination and perigee argument of the constellation configuration parameter has carried on the optimized design, which compensating the long-term function influence of the earth non-spherical perturbation and enhancing the ability of constellation self-stability. Through changing the orbit size and the shape of the orbital plane, it is realize to control the precession angle speed and the phase angle excursion. Finally, through simulation and. experiment to the space-based tri-satellite multistatic radar constellation, simulation results indicated the parameter optimization method enhancing the constellation configuration stability is effective, the on-orbit control method designed meets the maintenance requirement of the constellation configuration
