The invention discloses a low-altitude aircraft collision avoidance capability evaluation method based on various environmental factors, and the method comprises the following steps: 1), building a hemispheroid obstacle model, and comparing the height H of an obstacle with the maximum flight height Hmax of a low-altitude aircraft; 2) when H is less than Hmax, selecting climbing obstacle crossing for obstacle avoidance; when H is larger than or equal to Hmax, selecting a side obstacle avoidance mode for collision avoidance; and 3) evaluating the collision avoidance capability of the low-altitude aircraft based on the climbing obstacle crossing and side obstacle bypassing capabilities. The method has the advantages that theoretical guidance is provided for safety detection of the low-altitude aircraft, and the accuracy of low-altitude aircraft collision early warning equipment is improved; and a proper collision avoidance strategy is selected according to the collision avoidance risk.
本发明公开了一种基于多样环境因素的低空飞行器避撞能力评估方法,包括以下步骤:1)建立半球体障碍物模型,比较障碍物高度H与低空飞行器最大飞行高度Hmax的大小;2)H<Hmax时,选择爬升越障进行避障;当H≥Hmax选择侧面绕障的方式进行避撞;3)基于爬升越障和侧面绕障的能力,评价低空飞行器的避撞能力。本发明的优点是:4.为低空飞行器安全性检测提供理论指导,提高低空飞行器碰撞预警设备的准确性;根据避撞风险的高低,选择适当的避撞策略。
