Studying and accomplishing a new guidance law for homing missile attacking maneuvering target

By utilizing the design method of the linear-quadratic regulator, a new optimal guidance law for the infrared and radar homing missile which has good adaptability and high precision for attacking maneuvering target is derived. For resolving the important problem in engineering accomplishing, an adaptive statistical model of target maneuvering is proposed. Based on the statistical model of target maneuvering and nonlinear Kalman filter, a new algorithm which uses infrared AGC signal or radar range measure signal to estimate maneuvering targets acceleration distance and velocity between missile and target is proposed. The simulation of two missile control and guide systems prove that the algorithm has good stability and convergence.
