模拟数据

The key of the simulation is to select a suited set of models and parameters which represent the motion and the echo of moving targets, Because the perform of microwave radars operating over the moving targets is very complicated.In this paper, we discuss how to simulate the motion of targets with a method of parameters simulation. And then we get a track clearly through controlling the flight parameters and the time increasing. The way reduces the error.This paper also particularizes the prime parameter of the echo--Radar Cross Section which is influenced by many factors.
