Research on Construction Method of Maritime Environment Model Based on Distributed Electromagnetic Spectrum Monitoring System

In the complex environment at offshore, the value of background noise is not constant. The radio received signal strength fluctuates continuously due to constant changes in the rough sea environment. If a single preset noise threshold value is used for correlation calculation, the false detection rate and missed detection rate will increase. Therefore, this paper proposes a distributed electromagnetic spectrum monitoring system based on the real-time data of the nodes. Combining stochastic equations to construct a real-time sea surface model based on Markov chains. In order to improve the detection probability of the electromagnetic spectrum at sea.
