摘要
针对可变倾角连续断面节阵列(Variable Inclination Continuous Transverse Stub,VICTS)天线的波束指向误差问题,提出了一种补偿方法。首先介绍了VICTS天线的基本原理和组成,建立了波束指向模型。然后分析了误差来源,包括结构误差、馈源层及辐射枝节层的角度关系等因素,通过仿真得出了波束指向角与馈源层和辐射枝节层夹角的关系。在此基础上,提出了通过二次曲线拟合进行误差补偿的方法,并进行了对星试验。实验结果表明,该方法能够有效减小波束指向误差,提高通信系统的性能,具有较高的实用性。
In this paper,a compensation method is proposed to solve the beam pointing error of Variable Inclination Continuous Transverse Stub(VICTS)antenna.Firstly,the basic principle and composition of VICTS antenna are introduced,and the beam pointing model is established.Then the error sources are analyzed,including structural errors,the angle relationship between feed layer and radiating branch layer,and the relationship between beam pointing angle and the angle between feed layer and radiating branch layer is obtained through simulation.On this basis,the method of error compensation by quadratic curve fitting is proposed,and the satellite experiment is carried out.The experimental results show that this method can effectively reduce the beam pointing error and improve the performance of the communication system,and has high practicability.
