比幅测向是一种用来测量辐射源方位的侦察技术,广泛应用于雷达对抗系统中。介绍了比幅测向的原理,分析了产生测向误差的典型原因,提出了一种基于脉冲流测向误差曲线的校正方法,有效修正了系统因波束指向、波束宽度偏差等因素带来的误差。工程验证表明,该方法可以显著提高系统测向精度。

Amplitude comparison direction finding is a reconnaissance technology used to measure the azimuth of radiation sources and is widely used in radar countermeasure systems.This article introduces the principle of amplitude comparison direction finding,analyzes the typical reasons of direction finding errors,and proposes a correction method based on the pulse flow direction finding error curve,which effectively corrects the errors caused by factors such as beam pointing and beam width deviation,etc.in the system.Engineering verification shows that this method can significantly improve the direction finding accuracy of the system.
