摘要
应用线性二次高斯调节器原理，本文提出一种适用于脉冲多卜勒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。根据机动目标的统计模型和非线性最优滤波理论推导出一个快速跟踪的自适应滤波算法，并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。某改进后导弹的仿真结果表明该算法具有很好收敛性和稳定性。
By using the design method of the Linear Quadratic Regulator, for pulse Doppler radar homing missile, a new optimal law, which is of good adaptability, high precision and easy realization for attacking maneuvering target is derived. To resolve the important key in engineering application, an adaptive statistical model of target maneuvering is proposed. Based on the statistical model of target maneuvering and nonlinear Kalman filter, a new adaptive filter algorithm, which can rapidly track and estimate maneuvering acceleration of the target, the velocity and the distance between the missile and the target is proposed. The simulation for a certain improved missile control and guide system shows that the algorithm is stable and has good convergence property.
