The choise of solution during measuring the elevation angles of low-altitude targets with use of the root-MUSIC algorithm
Yu. A. Pedenko · 2013
As the optimal solutions choice which corresponds to target can be considered a method in which the target is assigned the angle of elevation that is closest to the direction equal to half the width of antenna pattern formed by the array antenna. Not yielding to the accuracy of other methods of solution choice, it is relatively easy to implement.
