摘要
部分频带压制干扰是现有的对跳频通信系统最有效的干扰方式之一。在分析了部分频带干扰对跳频同步和系统误码率影响的基础上,仿真了干扰条件下的同步捕获性能和系统误码率曲线。验证了部分频带压制干扰在覆盖同步频率时能有效降低同步捕获概率,当不覆盖同步频率时也能提高系统误码率,达到破坏敌方通信的目的。
Partial band blanket jamming is one of the existing most effective jamming modes to the frequency hopping communication system. Based on analyzing the influence of partial band jamming on frequency hopping synchronization and system bit error rate, this paper simulates the synchro- nous acquisition performance and system bit error rate curve under jamming condition, verifies the partial band blanket jamming can effectively reduce the probability of synchronous acquisition when it covers the synchronous frequency, and can raise the system bit error rate to destroy the enemy communications when it does riot cover the synchronization frequency.
