角跟踪信号的动态模拟

Dynamic Simulation of Angle Tracking Signal

为了检验天线伺服反馈源系统的性能和状态,要对角跟踪信号进行动态模拟。根据天线方向图中角度偏移与和差信号幅度的对应关系,通过控制和差信号幅度从而改变角度偏移,可以对角跟踪性能进行动态模拟。介绍了角度模拟在工程中的实现方法,分析了影响模拟精度的因素。实际工程应用验证了该方法的有效性。

For checking capability and performance of antenna servo feedback system, the simulation of angle tracking signal is needed. Based on the relationship between angle offset in directional diagram and sum- differ- ence signal amplitude, changing angle offset can realize dynamic simulation of angle tracking characteristics. In this paper, angle simulation implementation method is introduced, the factors influencing simulation precision are analysed. Engineering application verifies the feasibility of the proposed method.
