摘要
雷达无源工作时，可以接收和利用干扰信号对干扰源进行无源测向。分析了线扫雷达在现有设备条件下对噪声调频干扰源的无源测向误差；在此基础上，提出了提高无源测向精度的方法，并分析了其效果。
If a radar operates passively, it can obtain the objective of passive direction finding against a jamming source by means of receiving and utilizing the jamming signal. In this paper, passive direction finding errors of a linear scanning radar against a noise-frequency-modulation jamming source are analyzed on the existing equipment conditions; then methods of improving the passive direction finding precision are presented, and effects of these methods are also analyzed.
