A Field Theory-Based Novel Algorithm for Navigational Hazard Index

Collision risk assessment is crucial for autonomous ships to identify risks and make decisions collision avoidance. In this paper, a field theory-based navel algorithm proposed define describe the of ship collision. Based on theory asymmetric Gaussian function, constructed, potential used characterize navigational hazard index. The effectiveness superiority are verified through study cases. results show that can obtain index continuously, reflect level accurately, provide reliable basis navigation ships. Therefore, it has important application in development intelligence navigation.
