Lidar is an atmospheric sounding technique based on the use of high-power lasers. The use of these lasers involves fulfilling obligations with respect to air safety. As the lidar is equipped with a class 4 laser potentially dangerous for aircraft flying overhead the lidar, the air traffic surveillance including the possibility to shut off the laser is required by the international regulations.
Here, we present a low-cost air traffic surveillance solution integrated into an automated operating system for the Rayleigh-Mie-Raman lidar of the OPGC, Clermont Ferrand. Our original system is based on Software Defined Radio (SDR). The ADS-B transponder frames are acquired and analyzed in real-time, and the laser emission is stopped during lidar operation when an aircraft is detected within a 2 km radius around the lidar. During the initial period of validation, Laser shutdowns due to the detection of aircraft near the Clermont Ferrand lidar caused a data loss rate of less than 2%. The system has been accredited in 2019 by the French air traffic authorities.
