Micro-motion Modeling and Wideband Radar Echo Simulation of Midcourse Target

The micro-precession dynamics model was improved. And the micro-precession mathematic formulas were set up. The mid-course targets' traits were analyzed from the aspects of target shape,motion specialty and scattering specialty. And the moving scattering center model was raised. In the end,the simulation results provide important foundations to mid-course target recognition.
