Car Missile Target Signal Simulation System

This paper detailed studies the theory and method of stimulating the video frequency signal of MMW active detector on bomb.First, the reflective character of target is analyzed. It is indicated that the target can be modeled by a group of scattering points . Based on this principle, the back wave of the target can be obtained by composing the returns from these points . The software is designed and the results are given .Second, the character of the land clutter is analyzed. It is shown the clutter obeys certain statistical law. The random series is produced to stimulate the clutter. Finally, a circuit using chip computer(MCS8098) is designed to realize the signal simulation .By compared with the results of the practical experiments, is proved that the method put forward in this paper is feasible.
