| 摘 要： | 针对相控阵导引头离散波束运动引起视线角速率估计值跳跃波动问题,提出一种对波束角误差进行补偿的视线角速率提取算法。分析了相控阵导引头波束离散扫描原理,建立了波束扫描控制数学模型。推导了波束指向误差斜率引起的隔离度传递函数,分析并说明了波束角误差补偿方法。仿真结果表明,应用波束角误差补偿方法能有效地消除视线角速率提取值的跳跃波动,并验证了所提算法在捷联去耦与视线角速率提取方面的有效性。

| Abstract: | Aiming at the problem of fluctuation of line of sight rate estimate caused by phased array seeker discrete beam motion, a line of sight rate extraction algorithm is presented, which uses beam angle error compensation. The strapdown phased array seeker discrete beam motion principium is analyzed,and the mathematical model of beam scanning control is proposed. The disturbance rejection transfer function caused by beam angle direction error slope is derived. The method of using beam angle direction error compensation is analyzed and described. The simulation results show that by using beam angle direction error compensation method, the fluctuation of line of sight rate estimate can be effectively eliminated, and the algorithmic validity of decoupling and line of sight rate extraction is proved. |
