Features of multi-channel signal processing with a quasiring arrangement of receiving elements
Incoming article date: 04.03.2020Issues related to the features of multi-channel signal processing based on superresolution methods using a system with a quasi-ring arrangement of receivers are considered. The output characteristic is compared using the classical processing method (radiation pattern is formed) and the superresolution method (direction-finding relief is formed). As a basis of the signal processing algorithm, the property of 2π-periodicity of the angular dependence of the directivity characteristics of the receivers and the signal power is used. The issues of increasing the resolution in the angular direction of the received signals were studied during multichannel processing in a receiver system with a ring arrangement. The possibility of a significant improvement in resolution during the transition from the classical method to the method of superresolution is shown.
