An adaptive system for the attenuation of an intentional disturbance applied to a phased array type radar with mechanical scanning

摘要: 57 System for the cancellation of directional disturbances (jammers) by means processing signals received from radiating elements a phased array radar planar antenna. For formation beam in certain direction all are not combined amongst themselves; some these separately order to form auxiliary beams that allow estimation disturbance which is present main and its removal it. The system according invention does therefore require placement antennas around antenna and, much less, use multiple channels case when it desired control amplitude phase elementary radiators array. signal coming channel, with effects removed can be further processed usual techniques used receivers detect presence targets evaluate their kinematic parameters.
