The authors study broadband interference neutralization mechanism. Interference signals are produced by target-appertaining sources. Adapted data of target signal are processed by Doppler processor of master and compensatory channels. The proposed solution allows neutralization of interference signals that are produced by several sources with next to potential cancellation ratio, as well as maintains proper canceler operation in presence of underlying surface echoing. It is possible to employ mechanisms proposed in air-borne radar with phased antenna.
