Abstract :
Summary form only given. Some problems of phased array antennas and its T/R modules calibration are considered. The main attention is paid to the problems and procedures of diagnostics and measurements of amplitude and phase distribution on aperture, to alignment and calibrations of phased array antennas, which take into account the peculiarities connected with its hardware implementation and service conditions.
