Аннотация

A comprehensive method for increasing the resolution and accuracy of angular measurements by digital antenna arrays is proposed and substantiated. The problem of searching for coordinates of individual objects in the form of a group target, which are not resolved by direct observation, is considered. Mathematically, the problem is reduced to solving Fredholm integral equations of the first kind of convolution type with additional conditions. It is proposed to implement solutions with angular superresolution based on a new method based on excluding one of the components from the analyzed signal. The results of numerical experiments on a mathematical model are presented and analyzed.
