Description: The possibility of radiointerferometers application for upgrading reception/transmission of radar information and interference immunity in multisite radar complexes (MSRCs) is examined in the paper. The results of theoretical researches of energy and spatial performance of radiointerferometers are presented by example of double-channel radiointerferometer. The questions of the spatio-temporal coherent signal processing are considered against the background of active disabling interference in MSRCs. The small-base bistatic RC device chart for optimal signal processing is offered.
