Description
Summary:The results of synthesis and analysis of the effectiveness of the optimal location-based system for joint detection and estimation of informative parameters of quasi-determined radar signals with frequency modulated continuous wave are presented. A method has been developed for calculating the noise immunity indices of frequency modulated continuous wave radars and the detection threshold of signals in the quadrature channels of the optimal radar receiver based on off-center χ'2-distribution for given technical characteristics of the location system, including the mode of operation for detecting and evaluating parameters in multi-target mode.
