Paper Title
MEASURING THE SUCCESS OF UAV IRRADIATION INTERVENTIONS

Abstract
In December 2023, we conducted experimental measurements using the DJI Mavic 2 UAV at Jince military training area, Czech Republic, as part of the Aviation Protection Against Low-Energy Lasers project (PID: CK03000036) announced by the Technical Agency of the Czech Republic under the Transport 2020+ program. The aim was to study the effects of laser glare on drones flying at flight levels of 15–35 meters. The device was equipped with a 1-inch CMOS sensor that captures 20-megapixel photos and 4K video, making it ideal for experiments throughout the entire planned flight circuit. The sensors were mounted by the manufacturer in a count of 9. The instrument was equipped with two front and two rear optical sensors; one sensor was oriented sideways and two were oriented downwards. Additionally, the device was equipped with an infrared sensor facing downward and another facing upward. The purpose of the measurements was to assess the suitability of the optoelectronic system for detecting and locating low-power laser sources that pose a threat to air traffic safety. This paper presents an overview of the measurement results, including: 1) The experiment found a hit rate of 3.75% when the drone was irradiated by a red laser while the attacker was in a standing position with a support. 2) The size of the irradiated area in the camera’s field of view (FoV) increases with higher laser irradiance levels, and the glare is effective at irradiance levels around a few μW/cm².
