自寻的导弹攻击机动目标的最优制导规律的研究及实现

 提出一种适用于红外和雷达自寻的制导导弹的适应性强、制导精度高、易实现的最优制导规律。为解决工程实现的关键问题,提出了目标机动加速度模型。根据该模型并利用导弹导引头的AGC信号或雷达测距信号,给出了目标机动加速度、导弹与目标相对距离和距离变化率的估计算法。

RESEARCHING AND ACCOMPLISHING FOR HOMING MISSILE ATTACKING MANEUVERING TARGET

By utilizing the design method of the Linear Quadratic Regulator, a new optimal guidance law for infrared and radar homing missile which has good adaptability and high precision for attacking maneuvering targets was derived. For resolving the important problem in engineering accomplishing, an adaptive statistical model of target maneuvering was proposed. Based on the statistical model of target maneuvering and nonlinear Kalman filter, a new algorithm which uses infrared seeker AGC signal or radar seeker range measure signal to estimate maneuvering targets acceleration, distance and velocity between missile and target was proposed.The simulation results of two prototype missile controls and the reformed guide system proved the algorithm to have good stability and convergence.
