摘要
随着多功能、多用途雷达天线技术发展,要求越来越多的天线工作在多频段、宽频带,对于反射面天线来说,天线本身具有宽带特性,而馈源是实现多功能、多用途的关键。本文给出一种新型C/S双频馈源的实例,主要描述了C/S双频馈源工作原理和C频段多模三通道自跟踪馈源具体实现方法,通过与传统五喇叭体制的同类馈源的性能比对,总结出该新型馈源的几个特点。
As development of multifunctional and multi-purpose radar antenna technology, more and more antennas are required to operate in multi-band and broadband. For reflector antenna, the antenna has broadband characteristics and the feed is a key to achieve multi-function and multi-purpose. An example of a new C/S dual-frequency feed design is presented. The operational principle of C/S dual-frequency feed and specific implementing method of C-band multi-mode 3-channel self tracking feed is depicted. And several characteristics of new type feed are concluded by comparing with performance of same type feed of traditional 5-horn system.
