Abstract

The invention relates to a large unmanned aerial vehicle collision probability calculation method based on an STP model, and the method achieves the higher precision of a flight conflict detection model through the morphological optimization of the STP model and the introduction of a three-dimensional correlation stochastic differential equation and an elliptical STP model.

Description

technical field [0001] The invention relates to a method for calculating the collision probability of a large unmanned aerial vehicle based on an STP model. Background technique [0002] In recent years, the airspace traffic flow has grown rapidly, and the application range of large drones has become wider and wider. The fixed airspace range cannot meet the growing flight traffic demand for airspace use, so the conflict of airspace traffic has become more prominent. Judging from the actual application of the airspace traffic management mode at the present stage, the aircraft can only fly according to the prescribed planned route without special circumstances. During the flight, flight errors will occur due to its own factors and external factors, which cause flight errors. Including self-navigation errors, weather changes, and collision avoidance systems. In order to effectively improve the utilization rate of airspace and optimize the conflict detection scheme, exploring t...
