Research on Alert Strategy of Unmanned surface Vessel Based on Typical Missions

In a typical patrol alert mission, taking the circular patrol protecting fixed targets as an example, we propose an alert strategy under different detection ranges and warning circle ranges. When the unmanned vessel has global detection capability, based on the elevator algorithm, the maximum interception number and the optimal interception path is obtained. When the unmanned vessel has local detection capability, in the case of non-threat target intrusion, according to the radar detection probability model, the enemy interception quantity is maximized and the optimal patrol speed is obtained. For multiple threat target intrusions, a threat risk model is established and an optimal alert strategy is provided. In this paper, we build models for different situations, which are more specific and reasonable. The simulation test verifies that the alert strategy proposed in this paper is applicable to the patrol alert mission in various situations of unmanned surface vessel.
