基于相控阵雷达天线俯仰多波位相扫的设计与应用

摘要

分析研究了如何设计平面相控阵雷达天线多波位相扫的基本原理,提出了36行平面相控阵雷达天线在俯仰上实现多波位发射波束、接收波束形成与展宽方法.通过微波暗室的测试,天线技术指标完全达到了平面相控阵雷达天线多波位相扫的技术要求,实现了一维相控阵面高增益、高灵敏度、低噪声、大动态范围技术指标.%Analysis and research on how to design planar phased array antenna the basic principle of multi wave phase sweep,presented 36 line plane phased array antenna is implemented more wave emission beam on the pitch,the method of receiving beam forming and broadening.Through the test of microwave dark room,antenna technical indicators fully meet the multiple wave phase of the technical requirements,the one-dimensional phased array face high gain,high sensitivity,low noise coefficient,large dynamic range technology index.
