摘要
针对武器协同作战中相控阵天线追踪问题,提出了一种面向武器协同作战的自适应天线跟踪算法。自适应天线跟踪系统通过通信数据链获取目标的位置和姿态信息,结合系统自身的位置和姿态信息,通过自适应天线跟踪算法计算出相控阵天线指向的方位角和俯仰角。自适应跟踪算法引入位置姿态预测模型,在通信短暂中断的情况下仍可根据当前位置和姿态进行预测,实现自适应稳定跟踪。最后将自适应跟踪算法处理结果同应用场景结果比较,结果表明,仅在两极存在误差且误差不超过1°,系统跟踪精度满足战术武器协同数据链对天线跟踪指向的要求。
Aiming at the phased-array antenna tracking problem in weapon cooperative operations,this paper proposes an adaptive antenna tracking algorithm for weapon cooperative operations.The adaptive antenna tracking system obtains the position and attitude information of the target through the communication data chain,and then uses the adaptive antenna tracking algorithm to calculate the azimuth and pitch angles of the phasedarray antenna pointing by combining the system’s own position and attitude information.The adaptive tracking algorithm introduces a position-attitude prediction model to achieve adaptive and stable tracking based on the current position and attitude even in the case of a brief communication interruption.Finally,the results of the adaptive tracking algorithm are compared with the results of the application scenarios.The results indicate that there are errors only at the two poles and the errors do not exceed 1°,and the tracking accuracy of the system meets the requirements of the tactical weapons cooperative data chain for antenna tracking and pointing.
