Korets'kyj E. Increasing of interference protection of atmospheric probing system with using of acoustic interference suppresion autoregressiv filters

Statistical models of scattered acoustic signals and interference are developed. Expediency of using adaptive lattice filters to suppress activ interference in acoustic probing systems is substantiated. For the first time interference channal has been proposed to be used to suppress intensive acoustic interference in probing systems. A signal processiv algorithm permitting to effectively suppress passiv acoustic interference and taking into acount distinctive characteristic properties of the given type of interference from analogous one in radiolocation has been developed. Experimental data on the suppression of real activ and passive acoustic interference with help of the signal processing algorithms proposed under conditions of a modern airport have been obtained.
