Research on the model of Target´s trail and the detection simulation of air-defense radar

In the trace fusion system, it is the unitary way and high cost to get the data sources of air-defense radar. Aiming at those shortcomings, this paper gives a method to generate data based on the model of target´s trail and the detection simulation of air radar. The emphasis is placed on the model of target´s trail and the process of air-defense radar detection. Fist of all, the trail model is built up on the flight plane, and then converted into rectangular coordinates system. The radar detection model simulates the detection process to estimate whether the target can be found. The real-time trace data is obtained if the target is found. The experiments validated the models and algorithms.
