The articlle examines an unsolved part of general issue of research of direct digital methods of correlation-interferometer radio direction-finding. The purpose of the article is the optimization of direct digital method of correlation-interferometer direction-finding with double ?orrelation processing. As a result of the conducted researches it was defined that the basic parameter of equalization of dispersion of estimation error of direction on the source of radio radiation for the direct digital method of correlation-interferometric direction-finding with double correlation processing, which it is expedient to optimize, there is the size of frequency converting change. Theoretical optimization of the explored method for the cyclic model of frequency change was conducted. As a result of design dependence of middle deviation of estimation of direction from the relation of signal/noise at the action of normal gaussian noise for the different possible values of circular frequency converting shift was obtained. Analytical calculations and results of design fully coincided. Therefore the accuracy of the conducted researches and authenticity of results of optimization is confirmed. |
