Expression for the bottom boundary line of a matrix of a covariance of joint estimations of an azimuth and an angle of elevation of arrival of radio waves from sources of radio-frequency radiation by means of a multichannel detection-direction finder with antenna system of any configuration and directional characteristics of antenna elements are gain. The analysis of a potential exactitude of an estimation of the parameters by equidistant ring antenna lattices is carried out.
