Abstract

Possibility of creation of the correlation radiometer with the wide dynamic range on the basis of 4-level digitizer intended for research of variable space radio sources, including solar radiobursts is shown. Working characteristics of the 4-level digitizer with an adaptive quantization are determined and the technique of power and correlation measurements of accepted signals is offered.
