Task information is transmitted to a task allocator, which identifies unassigned targets and available USVs. Based on a comprehensive cost function considering navigation distance and turning penalties between targets and USVs, a target is assigned to each USV. A path planner then generates a smooth waypoint sequence for each assigned USV and target pair, serving as the navigation path. During navigation, a navigation controller constructs a velocity optimization model according to cooperative collision avoidance and maritime boundary constraints, and controls the USVs in real-time to navigate along the waypoint sequences.
