The traditional angle-fixed fuze has low initiating controlling accuracy when intercepting an object moving at high speed, such as a Tactical Ballistic Missile(TBM).Therefore, we proposed a new algorithm of adaptive control based on phased array fuze.The planar phased array technology was introduced in the algorithm to implement adaptive target tracking.On this basis, a new model of the optimum detonating angle was established.An adaptive initiating delay time was used to prevent explosion in advance because of beam stepping and realize intelligent coordination.Simulation indicates that this method can realize effective control of the optimum point of burst, and improve the kill efficiency to the target.
