The main complexity of spatial wideband signals processing under the conditions of radio interference consists in need of the provision of necessary frequency dependence of vector of weighting coefficients in all frequency range of useful signal processing. This frequency dependence is determined with chosen criterion of effectiveness of spatial processing. Such criterion is connected in this article with maximum of signal-noise-interference ratio. For realization of the optimal spatial wideband signals processing under the conditions of radio interference with different width of the spectrum in article is conducted generalization results got in classical work to narrow-band signal with reference to. For acknowledgement of efficiency of the presented method of spatial processing the wideband signal the process of useful signal with fourfold correlation upper and lower frequencies of the spectrum is considered. For spectrum of radio interference three events are considered. The first event - band of the frequencies occupied by radio interference complies with band of the frequencies of the useful signal. The second event - band of the frequencies occupied by radio interference is narrower than band of the frequencies of the useful signal. The third event - spectrum radio interference by complex image portioned within band of the useful signal. The presented results of the carried out investigations allows to set that «nulls» of the directive pattern are formed only on that frequencies on which spectrum of radio interference isn-t equal zero. This confirms the optimality of given method. The revealed regularities of the frequency distribution optimal weighting coefficients in channel of the processing the adaptive array can be used in development scanner assembly and justification its parameters.
