本文叙述非电扫描电子战(EW)天线。这些天线是现役装备中最常见的类型。虽然高性能EW系统趋向使用电扫描天线,这里所讨论的普通的固定宽波束天线和机械扫描天线将继续用于只对付威胁密度较低的新系统中。本文分成两部分来讨论两大类天线,即电子干扰(ECM)天线和电子侦察(ESM)天线。并且只限于讨论工作在20MHz以上频率范围的天线。两类天线的共同点是宽频带和要求有效地克服各种有害极化分量。本文还提出如何区分两类天线的要求和选用哪种天线满足这种要求的问题。
This article describes non-E-scan electronic warfare (EW) antennas. These antennas are the most common type of active equipment. While high performance EW systems tend to use electrosurgery antennas, the common fixed wide beam and mechanical scanning antennas discussed herein will continue to be used only in new systems with lower threat density. This article is divided into two parts to discuss two broad categories of antennas, the ECM and the ESM. And is limited to discussing antennas operating in the frequency range above 20MHz. The common ground between the two types of antennas is the wide band and the requirement to effectively overcome various harmful polarization components. This article also proposed how to distinguish between the requirements of two types of antennas and choose which antenna to meet this requirement.
