Abstract

Abstract: In the process of UAV avoiding obstacles, the tau warning logic based on time is introduced. Based on the tau warning logic, the τ-τ warning logic is proposed, and the equal τ-τ warning curve is constructed. According to the range of maneuver of the own UAV, three warning areas are defined, including high-risk area, low-risk area and non-risk area. Aiming at the two planes in the case of parallel encounter and vertical encounter, in accordance with three different situations of the UAV’s speed greater than, equal to and less than the intruder’s speed, the method simulates the warning curve of two aircrafts at different relative speeds with MATLAB software, proposing the division method of warning area, analyzing the difference between the warning areas of different encounter situation. The results of this experiment provide data support for the formulation of the UAV avoidance tactics.
