Research on judgment and restraining algorithm of track divergence in air traffic control system

Kalman Filter Equations of target tracking are described, all kinds of parameter matrix for the simplified calculation and corresponding initial value which are applied in air traffic control system are given, judgment method of track divergence and restraining algorithm are discussed in this paper. Concrete treatment algorithm and measure of application simulation are discussed, disperse criterion and restraining algorithm are applied to track dispose in air traffic control system. Simulation result indicates the algorithm can judge accurately track dispersing and restrain divergence effectively.
