Research on Clutter Simulation Method in Navigation Radar Simulator Training System

In the course of navigation, the targets echo displayed on the radar simulator often are suffered from clutter interference, and the common clutters includes rain&snow clutter, and wave clutter. In order to make the radar simulator better simulates the real environment, by analyzing the distribution characteristics of rain & snow clutter and sea weave clutter, this paper designs the clutter simulation display method based on Rayleigh distribution and Normal distribution, which can select the distribution characteristics according to the random characteristics of rain &snow clutter, and sea weave clutter, and simulate the real display effect of these two types clutter. The actual results show that the method proposed in this paper can meet the requirements of sea clutter simulation display application for navigation radar simulator.
