VICTS天线极化匹配算法研究

Polarization Matching Algorithm of VICTS Antenna

根据可变倾角连续断面节阵列(VICTS)天线极化调整的原理以及卫星通信和惯导数据的特点,提出VICTS天线极化匹配算法,该算法采用矢量运算和坐标变换的方法,得到VICTS极化控制层转动角度,实现VICTS天线的极化匹配。实验表明,相比传统的将极化控制层直接转动极化角的转动方式,采用该算法得到的接收信号强度提高了1 dB。

A polarization matching algorithm for variably inclined continuous transverse stub(VICTS)antenna is proposed based on polarization control principle of VICTS antenna,the characteristic of satellite communication and data of inertial navigation system(INS).Vector operation and coordinate transform are used to get the rotate angle of the polarization control layer and then polarization matching is achieved.Simulation results show that the received signal strength improves by about 1dB compared with traditional algorithm.
