В статье рассмотрены вопросы увеличения разрешающей способности РЛС за счёт применения параметрических методов обработки сигналов, таких как Capon, MUSIC, ESPRIT и некоторых других, указаны их достоинства и недостатки. Представлено решение проблемы оценки количества целей и корреляции эхо-сигналов, являющейся одним из факторов, ограничивающих их практическое применение. Приведены примеры работы метода MUSIC на математической модели РЛС.

This paper deals with the issues of increasing the resolution of the radar due to the use of parametric methods of signal processing, such as Capon, MUSIC, ESPRIT and some others, its advantages and disadvantages being presented. The solution of the problem of estimating the number of targets and correlation of echoes which is one of the factors limiting their practical application is presented. Examples of using MUSIC method on the radar mathematical model are given.
