Discussion on Some Key Problems of Jamming Initial Synchronization Head of Frequency Hopping Radio by Frequency Sweep Projectile-carried Communication Jammer

Abstract

From the perspective of jamming FH radio synchronization head, this paper took frequency sweep projectile-carried communication jammer as the research object. The key parameters of the FH radio’s initial synchronization head (including synchronization information hopping speed, synchronization information rate, jamming tolerance of initial synchronization information and so on), signal transmission loss under different conditions, and influence of sweep frequency were analyzed and discussed. The results showed that for the frequency sweep projectile-carried communication jammer, the free space environment should be selected to analyze the effect of jamming the synchronization head of frequency hopping radio, so as to avoid the influence caused by the change of sweep frequency. The conclusion can be used as a reference for further study on the jamming performance of projectile-carried communication jammer for FH radio synchronization head.
