The controllers fluctuate wildly because of the fighter maneuvering in air combat engagement process, which has effect on fighter’s performance and pilot’s controlling. According to the optimal problem of guidance strategy, an approximate optimum of engagement maneuvering strategy with allowable deviation is proposed. Firstly, three degree of freedom motion model is built. At the same time, the solution steps of angle deviation are put forward. Secondly, the discrete nonlinear programming model is built and the restriction and objective function are analyzed. After that, it introduces receding horizon control and proposes a numerical solution of controlling process. At last, an example of forward hemisphere attack is designed to comparing proportional navigation strategy with the designed engagement maneuvering strategy. The result shows that the latter’s controllers fluctuate more smoothly. Therefore, It is an effective strategy which can lighter pilot’s operation pressure.
