一种加密的弹载通信干扰机部分频带干扰信号

An Encrypted Projectile-carried Communication Jammer with Partial Band Interference Signal

针对弹载通信干扰信号易被敌截获的现实问题,以多音干扰信号为基础,并采集部分音频干扰信号作为原始弹载通信干扰信号,经过信号放大等预处理,选用基于Logistic映射的离散混沌加密方案,对原始干扰信号进行了加密处理。最后在MatlabGUI平台下开发了弹载通信干扰信号加密演示界面。

Aiming at the fact that the jamming signal of projectile-carried communication is easy to be intercepted by the enemy,based on the multi-tone jamming signal,and taking partial audio jamming signal as the original projectile-carried communication jamming signal ,after signal amplification and other pretreatment,the discrete chaotic encryption scheme based on Logistic mapping is selected to encrypt the original jamming signal.Finally,the encryption demonstration interface of projectile-carried communication jamming signal is developed on the platform of Matlab GUI.
