一、简介在导弹跟踪系统中,采用比相式的单脉冲体制具有其一定的先进性。目前,国外某些型号是采用这种体制。本文叙述了相位单脉冲天线的基本原理及其一般特性,分析了二天线单元的幅值、相位不一致性和反射干扰信号对天线系统性能的影响。同时,还通过实验,验证了这些因素对天线性能的影响。
I. INTRODUCTION In the missile tracking system, the phase-by-phase single pulse system has its own advanced features. At present, some foreign models are using this system. This paper describes the basic principle and general characteristics of phase single pulse antenna, and analyzes the influence of amplitude and phase of two antenna elements and reflection interference on the performance of antenna system. At the same time, we also verify the influence of these factors on the antenna performance through experiments.
