Abstract

The article proposes a mathematical model that allows us to evaluate the impact of differences in the characteristics of reception channels on the quality of noise suppression in radio devices equipped with antenna arrays.The influence of differences in the bandwidth of receiving channels, settings of their central frequencies and electrical lengths was studied. The dependences of the losses of the average interference suppression coefficient on the dispersion of parameters of differences in the characteristics of receiving channels are presented.It is advisable to use the proposed model when justifying the requirements for the permissible difference in the characteristics of reception channels of designed radio devices
