| 摘 要： | 对电磁波的极化特性进行了研究,提出一种利用电磁波极化特性进行测角的方法,采用正交偶极子天线接收信号,并将信号综合成左旋信号与右旋信号,通过对两个信号进行比相的来测向.利用一个参考相位解决了测角模糊的问题.分析了噪声和信源入射角度对测角性能的影响,指出在信噪比较高时其测角精度与信源入射角度无关,只与信噪比有关.计算机仿真和对实验结果的分析证明了该测角方法的可行性和分析结果的正确性.

| Abstract: | A direction-finding method is proposed,uses phase comparison of left-hand polarization and right-hand polarization signals synthesized from signals received by orthogonally cross dipole antenna.A reference phase is utilized to solve the angular ambiguity problem.The effect of noise and incidence angle of signal source on angle measurement performance is analyzed,which indicates that angle measurement accuracy is independent of the incidence angle of the signal source.Computer simulation and experimental res... |
