电子战接收机测向测频精度提高方法
A Method for Improvement of Direction Finding and Frequency Finding Accuracy of Electronic Warfare Receiver
摘要
Abstract
Abstrct For EW receivers,azimuth information and frequency information are the two most important parameters.In this pa-per,a method of amplitude comparison direction finding based on secondary correction technology is proposed,and a symmetrical re-sistance ring is used to eliminate the phase offset caused by DC potential.Based on this,a new IFM receiver for amplitude compari-son direction finding is designed.This receiver is not only small in size,but also has high accuracy of frequency and direction finding.关键词
