Impact of the barrage jamming on communication effectiveness of VHF frequency-hopping radio

Abstract

This paper focuses on the communication effectiveness (CE) of VHF frequency-hopping (FH) radio when threatened by the barrage jamming (BJ) in actual environment. First, a FH radio simulation model is built on the Simulink platform based on VHF FH radio's operating principle. Then, the jamming signals are quantified classified by their threat level and simulations of jamming signal from typical paths are made. Finally, emulated studies are made on effects of CE for wideband BJ and comb BJ with different threat level on different FH rate and different FH bandwidth. Also, a hardware-in-the-loop system is also built to verify the simulation results. Corresponding results are drawn.
