The noises generated by the high level impulsive sources propagate a great distance away, but their characteristics can be strongly modulated by environmental parameters (inhomogeneities in the atmosphere, ground’s characteristics). The performances in terms of detection and localization of sources are disrupted by the spatial and time fluctuations in these parameters. This contribution presents the current efforts at ISL to measure, understand and predict this variability. Experimental tests are realized at various propagation ranges. The results illustrate the variabilities in terms of level, spectral content and precision of the angular localization. The metrology, identification and forecast of the relevant environmental parameters to explain these fluctuations in performance will be discussed.
