Threat modeling and assessment of unmanned aerial vehicle under complicated meteorological conditions

To study the effect of meteorological conditions on Unmanned Aerial Vehicle(UAV),an algorithm of multi-level fuzzy comprehensive evaluation method based on threat value was proposed.This algorithm improved a two-level weight value determination and the comprehensive evaluation model,which can get the comprehensive threat index after being calculated.The simulation results show that this algorithm can assess the degree of weather threat accurately and have faster operation speed,smaller error and lower complexity.The efficiency and validity have also been improved.
