Algorithms of multichannel detection of plane monochromatic radio waves by a system of multichannel detection-direction finders, efficient in the conditions of aprioristic uncertainty of direction finder antenna systems' characteristics and intensity an additive Gaussian noise are developed. The solving rule of algorithm, adaptive to a priori unknown characteristics of antenna systems of direction finders, is gained as a result of a maximization of the relation of likelihood by means of estimations of basic matrixes of spatially multichannel systems. In case of one measurement the solving statistics of the given algorithm has a structure inherent to power detection. The solving rule of detection algorithm, which is adaptive to unknown intensity an additive Gaussian noise, is gained as a result of a maximization of likelihood relation by unknown parameters and as solution of system of likelihood equations. The case multiscale direction finding systems is considered, for which the exact solution of system of likelihood equations is found. Algorithms of adaptive detection are developed in the assumption of any configurations of antenna systems of detection-direction finders and structures of noise covariance matrixes. The gained solving rules consider spatially multichannel structure of system of detection-direction finders and allow to detect plane radio waves in conditions of aprioristic uncertainty of various degree.
