A Low intercept technology for uuv cluster's covert underwater acoustic communication
This study addresses the problem of insufficient concealment in underwater acoustic communication during the task of underwater unmanned vehicles(UUV)or autonomous underwater vehicles(AUV)cluster(hereinafter referred to as UUV cluster).Firstly,an analysis model of underwater acoustic concealment communication for UUV cluster is estab-lished,and the factors affecting the concealment of underwater acoustic communication and the technical approaches to achieve concealment communication are clarified.Then,from the perspective of engineering practice,a method for realizing low-interception technology of underwater acoustic concealment communication for UUV cluster based on time-frequency-space and transmit power control is proposed.A comprehensive measure of beam direction,broadband hybrid spread spec-trum coding communication,and variable step size transmit power control is used to design the underwater acoustic conceal-ment communication system.The performance simulation results show that the above methods can greatly improve the low-interception performance of underwater acoustic concealment communication for UUV cluster.
