Abstract

In this article an estimation of the influence of the limits of dynamic range of radio receivers (RPPs) on the qualitative parameters of on board radio systems is carried out, using a toolkit as a functional method, which is based on the determination of Volterra cores, which makes it possible to optimize them according to the criteria of nonlinearity. As a result of the research, the concept of effective signal-tonoise ratio at the input of equivalent linear RPP is grounded on the basis of the system analysis of the integral influence of the nonlinearity of the amplitude characteristics of the real RPPs, as well as to determine scientifically grounded requirements of their parameters, based on the required values of the indicators of the quality of on-board radio systems. The obtained results testify to the necessity of suppressing the nonlinear processes occurring in the RPP by reducing the level of nonlinear distortions of the third order.

Keywords: radio device, nonlinear process, dynamic diapason, systematic analyses, functional method, Volterra cores, indicators of quality, on-board radio system.
