为实现弹体姿态扰动下相控阵捷联导引头对目标的稳定跟踪,提出一种结合失调角信息处理与弹体姿态信息计算波束控制角指令,实现相控阵导引头捷联去耦并产生视线角速率的算法。分析了相控阵导引头波束运动原理,进行了弹目线跟踪所需波控角指令的计算推导,说明了视线角速率提取算法,并对算法去耦及视线角速率提取效果的影响因素进行了分析。仿真结果表明,通过理想的增益参数设置,特定弹目线运动下的算法角跟踪误差及角速率估计误差较小,验证了算法在去耦与视线角速率提取方面的有效性。
In order to realize the stable tracking of the phased array strapdown seeker on the target under the disturbance of projectile attitude, this paper proposes a method to calculate the beam steering angle command by combining the disproportion angle information processing and the projectile attitude information to realize the phased array seeker strapdown The algorithm that couples and produces line of sight angular velocity. The principle of beam steering of phased array seeker is analyzed and the calculation and derivation of wave control angle command required for projectile tracking is described. The algorithm of extracting angular rate of line of sight is described, and the influencing factors Analyzed. The simulation results show that the proposed method can reduce the error of angular tracking error and estimate the angular velocity under the condition of specific projectile motion, and verify the effectiveness of the algorithm in decoupling and viewing angular rate extraction.
