Активное использование беспроводных технологий требует развития средств контроля беспроводных сетей передачи данных, в частности сетей Wi-Fi. Службами радиоконтроля решаются задачи обнаружения, идентификации и локализации не санкционированно работающих точек доступа и абонентских устройств. Эффективным инструментом пеленгования радиосигналов являются корреляционно-интерферометрические пеленгаторы на базе двухканальной приемной аппаратуры и многоэлементной антенной системы. Развитие методов совместной идентификации и пеленгования позволяет разделять пеленги большого количества источников сигналов, ведущих работу в одном частотном диапазоне с разделением по времени. В настоящей работе акцент сделан на обнаружении целевых сигналов и выделении из них идентификационных признаков источника. От успешности реализации этих операций будут существенно зависеть и показатели качества пеленгования.</p><p>Целью работы является исследование возможностей повышения помехоустойчивости обнаружения и идентификации сигналов Wi-Fi за счет совместного использования двух каналов приема корреляционно-интерферометрического пеленгатора. В работе использованы методы статистического компьютерного моделирования, которые учитывают наличие замираний, возникающих из-за многолучевости канала распространения, и корреляцию радиосигналов, вызванную близким расположением приемных антенн.</p></sec><sec><title>Решение</title><p>Решение.

The active use of wireless technologies requires the development of controls for wireless networks, in particular Wi-Fi networks. Radio monitoring services solve the tasks of detecting, identifying and localizing unauthorized access points and clients. An effective tool for bearing radio signals is correlation interferometric direction finders based on two-channel receiving equipment and a multi-element antenna system. The development of methods of joint identification and bearing makes it possible to separate the bearings of a large number of signal sources operating in the same frequency range with time division. In this work, the emphasis is placed on the detection of target signals and the identification of source features from them. The indicators of the quality of bearing will also significantly depend on the success of these operations.</p><p>The aim of the work is to investigate the possibilities of increasing the interference resistance of detecting and identifying Wi-Fi signals through the combined use of two channels of a correlation interferometric detector.</p></sec><sec><title>Methods</title><p>Methods.
