Within the program of work of SET-260, a NATO joint trial was organized to collect UAV EO/IR signatures of UAVs in different bands with an urban background. The trial took place in CENZUB, the French armed forces training center for urban combat, in June 2019. In this paper, we present details of this trial and discuss the challenges, pros and cons of detecting UAVs in the different EO/IR bands.en004670presentation
