Пасивні методи визначення місцезнаходження БПЛА з акустичного випромінювання

Abstract

Methods for direction finding of unmanned aerial vehicles in radar and acoustic systems designed to detect and measure the coordinates of aircraft are considered. The advantages and disadvantages of the main types of methods are analyzed. Direction-finding methods implemented using antenna arrays are considered. It is shown that modern methods and algorithms with superresolution, implemented using adaptive antenna arrays, allow solving the problem of determining the coordinates of several sources separated by a sufficiently small angular distance.
