… Our approaches to ensuring the stability of the DIP solution (truncated singular
decomposition (TSVD) and random projection (RP)) use the integer regularization
parameter, which is the number of terms of the linear model. Regularization with an integer
parameter makes it possible to provide a model close to the best in terms of the accuracy of
the input vector recovery, and also to reduce the computational complexity by reducing the
dimensionality of the problem. The purpose of the article is to develop an approach to …

The purpose of the article is to develop an approach to estimating the direction of arrival of signals in the antenna array using the DIP solution, to compare the results with the well-known MUSIC method, to reveal the advantages and disadvantages of the methods.
