The invention provides an air target short-term conflict detection method, which belongs to the technical field of air traffic control, and comprises the following steps of: rasterizing the airspace of the whole flight process according to a horizontal safety interval parameter and a vertical safety interval parameter to obtain a plurality of airspace grids, establishing a space three-dimensional coordinate in the whole flight airspace, and calculating the short-term conflict of an air target. Marking each airspace grid according to the spatial three-dimensional coordinates, if two air targets are calculated to be in the same airspace grid, directly carrying out conflict early warning, and if two air targets are calculated to be in two adjacent airspace grids, possibly generating conflict, further calculating the horizontal distance and the vertical distance of the two air targets, and judging whether the two air targets are in the same airspace grid or not. And finally judging whether the two aerial targets conflict or not in combination with the horizontal safety interval parameter and the vertical safety interval parameter. According to the method, the operand in the alarm judgment process can be greatly saved, and the detection efficiency is improved.
本发明提供了一种空中目标短期冲突检测方法,属于空中交通管制技术领域,将整个飞行过程的空域按照水平安全间隔参数和垂直安全间隔参数进行栅格化,获得多个空域栅格,在全飞行空域内建立空间三维坐标,根据空间三维坐标标记每个空域栅格,若计算出两个空中目标处于同一个空域栅格中,则直接进行冲突预警,若计算出两个空中目标位于相邻的两个空域栅格中,则有可能发生冲突,进一步计算两个空中目标的水平距离和垂直距离,结合水平安全间隔参数和垂直安全间隔参数最终判断两个空中目标是否存在冲突。本发明方法能大大节约告警判断过程中的运算量,提高了检测效率。
