Decision Simulation of Chaff Centroid Jamming Against Anti-ship Missile

The models of anti-ship missile tracking, ship evasion, chaff movement and centroid movement were put forward by analyzing the chaff centroid jamming principles, and a chaff centroid jamming effect model based on three constraints was given. At last, the complicated dynamic jamming process was simulated by Matlab, and based on it, the relationship between effect of chaff centroid jamming and some elements was analyzed, which included missile threat direction, the launching shipboard of jamming shell, the evasion directions of ship and the speed and direction of wind.
