The revised edition of the three-volume (1974-1976) consists of two parts corresponding to two main tasks of statistical radio engineering: probabilistic analysis of the passage of stochastic signals through typical systems and statistical synthesis of systems for detecting, distinguishing signals and estimating their parameters against the background of interference with complete a priori information and under conditions of a priori uncertainty. The structure and logical sequence of the material remains the same. Some sections of the three-volume volume are not included, of interest to a narrower circle of specialists, but a number of new chapters and new results have been added along with a modern interpretation of known provisions.
