Abstract

Laser beams can be detected when propagating in the atmosphere, even if they are not pointed straight on the sensors. Mie scattering on aerosols allows to detect off-axis beams and to localize the source thanks to their geometric, spectral and temporal properties. In the recent years, Onera has conducted both theoretical and experimental studies to detect off-axis non cooperative pulsed laser beams in the lower atmosphere. Some simulations are presented, based on propagation and scattering physics. Experimental results are discussed.
