Abstract:

Ground Moving Target Indication (GMTI) using Spaceborne Radar (SBR) gives the opportunity for large scale surveillance,such as spying,target tracking,and positioning.It is specially valuable for military application.Utilizing the space domain sampling character of distributed spaceborne SAR for GMTI is attractive to researchers.Simulation is an important way to carry out the study of distributed spaceborne SAR-GMTI system.The simulation method and flow are discussed comprehensively in this paper,including ground clutter model,ground moving target model,return signal simulation method and signal processing flow and method.Based on the small facet model and the scatter characteristic of the rough terrain,3D ground scene clutter model is established.The received signal expression is formulated.An integrative distributed spaceborne SAR-GMTI simulation system is established,and the simulation results proved its reliability.
 

Key words: Distributed Spaceborne SAR    GMTI    System simulation
