Adaptive algorithms for detecting and measuring the angular position of the received signals against the background of spatially cor-related noise in multichannel radar are considered. The construction of signal processing algorithms in the receiving-solving devices of multichannel radar systems is associated with overcoming a priori uncertainty. In the case of Gaussian statistics of signals, spatially correlated and intra-receiver noises, the known processing algorithms include the operation of weight summation by correlation feed-backs, which increases the volume of computational operations. It is of interest to consider algorithms for multichannel signal detection and estimation of their angular coordinates in the scanning mode in the presence of spatially correlated noise, synthesized on the basis of a generalized criterion of the likelihood ratio. As a result of the calculations, the values are obtained for different volumes of sample data. The characteristics of the proposed algorithms are close to those of the known algorithms. The results show that in the above algorithms the compensation of spatially correlated noise is carried out without the use of correlation feedbacks, which reduces the amount of computational operations in the implementation.
