摘要
在短波空间谱侦测系统中,由于频段内信号密集,同频、同信道信号大量出现,需要空间谱测向技术对信号高精度、高分辨测向同时,通过数字波束形成技术实现小音点监听,充分发挥测向员的听觉潜能,实现信号音频属性与信号方向相对应。研究一种数字波束形成算法,采用该算法的空间谱侦测系统能实现小音点监听,有利于对感兴趣的目标信号侦测。
In HF direction finding system,there are a great lot of co-frequency and co-channel signals. The system realizes min-sound listening through beamforming technique, which can distinguish HF signal by its sound and DF. A new method for design of digital beamformer is studied.This method provides the min-sound of HF sigual,which is helpful for the direction finding of interested HF signal.
