Research on UAV Collision Avoidance Strategy Considering Threat Levels

This paper classifies the threat levels and studies the methods of UAV collision avoidance considering the threat levels, establishes the collision avoidance control strategy using UAV heading angle control, speed control, and the combinations of the two above strategies, and establishes a multi-objective cost function model and a multi-objective optimal decision method. Carrying out simulation experiments, we analyze the effect of UAV collision avoidance strategy through heading angle and speed changing.
