摘要:

数字干扰合成的雷达干扰技术,是针对作战对象事先准备好基带干扰波形数据,在干扰实施时从存储器中读出,经过数模转换、模拟或数字变频等,产生射频干扰信号。DJS的样本并不一定是实时采样信号,在干扰时可根据对象的变化,重新填充新的干扰波形数据,具有较高的灵活性,对多信号、多威胁、多雷达、复杂调制电磁环境的适应性,正逐渐取代非相参模拟频率源(VCO)的干扰方式。

关键词: 数字干扰合成;直接数字频率合成;压制干扰;线性调频信号

Abstract:

As a new technology of Radar Jamming,Digital Jamming Synthesis is playing more and more important role in the modern war.The sampling signal of DJS should not necessarily be real-time.It can be changed by objects in the suppression,and the memory can re-fill the new waveform data.After digital to analog conversion and up-conversion,it can generate radio frequency interference signals.This technology has a lot of advantages,such as flexibility,adaptability of multi-signals,multi-threat,multi-radar,and the disturbance of VCO has been replaced gradually.

Key words: digital jamming synthesis;DDS;suppression jamming;LFM
