摘　　要：通过构建相控阵天线角跟踪回路模型并进行仿真,用于辅助设计角跟踪回路中α-β滤波估计算法的参数以及整个回路的闭环周期、延迟时间。首先,介绍相控阵天线角跟踪系统的设备组成,并基于此构建角跟踪回路的仿真模型;其次通过阶跃信号测试角跟踪回路的动态响应性能,并基于此确定滤波估计算法参数以及跟踪回路的闭环周期、延迟时间;进一步采用等速/正弦信号模拟飞行目标的机动特性,对角跟踪回路的滞后误差进行仿真,验证设计参数是否满足系统的使用需求;最后,利用正弦信号模拟天线载体平台的扰动特性,通过环路滞后误差仿真验证角跟踪回路的抗扰性能,再通过对滤波估计算法进行简单改进,提高回路的抗扰性能。实验结果表明:通过对角跟踪回路的建模仿真,能够快速实现角跟踪回路中各环节的参数及算法设计,大幅减小了试错成本。By constructing an angle tracking loop model and performing simulations in the phased array TT&C(Telemetry,Tracking and Command)system,it is used to assist in designing the parameters for theα-βfiltering estimation algorithm in the angle tracking loop and the closed-loop period and delay time of the entire loop.Firstly,the equipment composition of the phased array antenna angle tracking system is introduced,and a simulation model of the angle tracking loop is constructed.Then,when the parameters of the filtering estimation algorithm and the closed-loop period and delay time of the angle tracking loop change,the step signal is used to test the dynamic response performance of the angle tracking loop,and based on this,the design parameters of each link in the loop are determined.Subsequently,constant-velocity signals and sinusoidal signals are used to simulate the maneuvering characteristics of the flight target,and the lag error of the angle tracking loop is simulated to verify whether the design parameters meet the usage requirements of the system.Finally,the sinusoidal signal is used to simulate the disturbance characteristics of the antenna carrier platform.The anti-disturbance performance of the angle tracking loop is verified through loop lag error simulation,and by simply improving the filtering estimation algorithm,the anti-disturbance performance of the loop is improved.Experimental results demonstrate that modeling and simulation of the angle tracking loop enable rapid parameter and algorithm design for all components in the loop,significantly reducing trial-and-error costs.
