一种多频点干扰信号产生方案

在电子对抗领域,通常以同时输出多个载波信号对跳频等抗干扰通信实施干扰。分析了针对跳频通信的各种梳状拦阻式干扰方案的优缺点,设计了一种基于锯齿波线性调频技术的干扰方案。该方案能在保持时域等幅波形的前提下,产生多个离散的梳状谱,有效利用功率放大器的功率容限,适合于通信训练中模拟干扰环境。同时给出了基于数字信号处理器(DSP)、ROM、RAM,以及信号产生软件包组成的数字化多频点干扰信号产生器的实现,并对实现结果进行了分析。

A multi-frequency generation scheme of interference signal

In the field of electronic countermeasures,usually handles multiple carrier signals such as interference with communications on the implementation of frequency hopping interference.Analysis of frequency hopping communications for a variety of pectinate spectrum jamming the advantages and disadvantages,design a linear frequency modulation technology based on the interference of saw-tooth solutions.The program can maintain the time-domain waveforms under the premise of equal amplitude,resulting in multiple discrete pectinate spectrums,and the effective use of the power amplifier sufferance for interference in the training simulation environment.Also given based on digital signal processor(DSP),ROM,RAM,and signal generation software package composed of a digital multi-frequency interference signal generator implementation,and achieving the results are analyzed.
