比幅比相测角系统信号处理技术研究

Discussing some questions of signal processing in measuring angle system by comparing amplitude and phase

比幅比相测角是宽带被动雷达导引头测向系统中的一种重要方法,该系统结构简单,信号处理量小,因而得到了广泛的应用.针对比幅比相测角系统中存在的实际问题,重点研究了比幅比相系统中消除多值模糊的方法,提出了曲线拟合及对雷达脉冲采样等技术提高该系统测角性能.

Measuring angle by comparing amplitude and phase is an important method in wideband passive radar seeker technology.This system has simple structure and reduces computational complexity,so this method finds wide application.In order to improve the system ability,this paper put emphasis on discussing how to clear up excessive angle,fit curve,sample radar pulse,based on the practical problem in the system.
