引言在选择任何一种天线时,除考虑增益和方向特性外,天线极化也是很重要的。对于测向和极化识别以及信号截获用的警戒天线来说,极化就成为一种关键性的参数。选择合适的极化能使系统灵敏度和测向精度达到最佳。本文概述了与警戒使命有关的天线极化原理。讨论了可产生各种极化的各种各样的天线和选择天
Introduction In choosing any type of antenna, the polarization of the antenna is also important, in addition to gain and directional characteristics. Polarization becomes a critical parameter for guard antennas for direction finding and polarization identification and for signal interception. Select the appropriate polarization system sensitivity and direction accuracy to achieve the best. This article outlines the principle of antenna polarization associated with vigilance missions. Discusses a wide variety of antennas and select days that can produce a variety of polarizations
