抗目标辐射源关机的能力是反辐射导弹的关键战术技术性能之一，采用增广状态的广义卡尔曼滤波（EKF）与Sage－Husa自适应滤波相结合的方法，解决了在被动雷达导引头测量存在常值偏差和随机噪声，且随机噪声方差未知情况下所测角度的滤波问题，从而在目标辐射源关机时刻较精确地建立起目标视线在惯导坐标系中的方位坐标（简称惯性基准），进而利用速度追踪法导引导弹攻击目标。给出了以某型导弹为背景的全空间弹道数学仿真结果。 The ability to turn off the target radiation source is one of the key tactical and technical performance of the anti-radiation missile. The method of combining the extended state generalized Kalman filter (EKF) and the Sage-Husa adaptive filtering solves the problem that the passive radar- There is a constant value deviation and random noise in the head measurement, and the filtering problem of the measured angle under the condition of unknown random noise variance, so that the azimuth coordinates of the target sight line in the inertial navigation system can be established more accurately at the time of turning off the target radiation source Benchmark), and then use the speed tracking method to guide the missile attack target. The full space ballistic mathematical simulation results based on a missile are given.
