Effect analyses on interference against underwater acoustic frequency hopping communication

FH (frequency hopping) technique is widely used in underwater acoustic communication due to its good performance on anti-interference and anti-fading. In addition, communication might encounter intentionally destruction such as jamming. So it is necessary to make an effect evaluation on FH communication under jamming. Firstly, FH communication system with three typical jamming styles including partial band noise jamming, multi-tone jamming and pulse jamming. And a new jamming method called multi-tone hopping jamming against FH communication system with fixed frequency suppression is proposed. Their interference effects are analyzed. As a result, the optimal jamming styles in the specific environment are recommended. Which may provide guidance to jamming pattern selection for the FH communication system in practices.
