Abstract
An Autonomous Collision Avoidance Navigation System comprising navigating a route between a first location and a second location using a route tracking algorithm, detecting an obstacle and the obstacle's bearing, speed, distance, and direction of travel with respect to ownship, determining whether a collision between the ownship and the obstacle is probable, reducing ownship speed when a collision distance is less than a predetermined distance, determining a new heading using fuzzy logic and MCAD, and changing ownship course to the new heading, and to resume the route tracking algorithm when the obstacle is cleared from probably collision.
