A UAV flight path planning method for intelligent identification of threat types

Abstract

The invention discloses a flying path planning method of unmanned plane capable of intelligently identifying threat types. The unmanned plane flying path planning method can intelligently identify threat types and search the best flying path under mixed environment. The method comprises a detection period and an operation period. The detection period is that a plurality of detection bodies conduct detection together to complete the basic cognition of the search area. The method mainly comprises the steps of node information value update, dynamic threat identification, and static threat avoidance, and the forming of basic optimization route. The operation period is that a single unmanned plane completes practical path searching. By means of the basic cognition formed at the detection period, the static threat can be accurately prevented in a practical executing period, the dynamic threat can be identified at an early stage, and the optimized route can be planned rapidly. Accordingly, the unmanned plane can arrive at destination safely and rapidly.

Description

technical field [0001] The invention relates to the field of threat identification in mixed environments and real-time calculation of flight paths, in particular to a flight path planning method for intelligently identifying threat types. Background technique [0002] UAVs need to pass through a certain physical area when performing flight missions, and attack or reconnaissance targets in the area. The UAV needs to find the optimal flight path to ensure that it can reach the target point safely from the starting point. In the process, the UAV needs to avoid the enemy's defense forces in the area and the obstacles of the natural environment, so that the UAV can reach the destination safely. land. [0003] The pre-set area is the space for the UAV to plan the route, but there are generally threats such as natural terrain, weather, electromagnetic interference, and enemy air defense and anti-aircraft artillery. The sources and forms of threats are diverse, and threats are ana...
