In the article the method of application of phase correction into the reception channels of small-based correlation-phase direction finders with different distances between antennas of correlation-phase direction finders and calibration antenna has been given. This method takes into account the phase distortion of calibration signal, arising from the calibration antenna location in the Fresnel zone of measuring antennas of correlation-phase direction finders. Also the phase error arising from guidance inaccuracy of measuring antennas of correlation-phase direction finders to calibration antenna has been evaluated.
