Autonomous Collision Avoidance Tradespace Analysis for High-Speed Vessels

Abstract

In this work, a tradespace was introduced allowing a weighted combination of a course change and speed change when deviating from the preferred velocity vector in protocol - constrained autonomous collision avoidance algorithms. A novel iterative geometry testing technique was introduced and key evaluation metrics were studied including the introduction of a protocol - compliance metric for collision avoidance scenario s. The performance metric results differ ed for high - speed vessels indicating a need for parameter tuning specific to high - speed vessels before applying collision avoidance algorithms tested on slower vessels.
