Line-of-Sight Angle Rate Reconstruction for Phased Array Strapdown Seeker

摘要：

　　The phased array strapdown radar seekers detecting information is coupled with missile attitude information.Hence,the measurement information can not be used for proportional navigation directly.The method of reconstructing inertial line of sight (LOS) rate in phased array strapdown seeker is presented using the missile-target relative motion geometric and filtering algorithm.Considering measurement noise and nonlinearity of the phased array strapdown radar guidance systems,the principle of unscented kalman filter (UKF) is introduced to estimate LOS rate.The simulation results show that the reconstruction method is correct and the extraction of LOS rate is effective.
