The problem of measuring and recovery complex amplitudes of incident waves in the radiators channels of a linear antenna array, with directly connections between of radiators and a power division system – passive beam forming network, using a multi-element probe device, located in its near zone is considered.

The aim of work is construction of a mathematical model for estimating the error of measurements of the amplitude-phase distribution of incident waves in the radiators channels of linear array, taking into account the features of its measurement and recovery using the results of preliminary calibration of the measuring system.

A mathematical model for estimating the error of the amplitude-phase distribution measurement of incident waves in the radiators channels of linear array with the passive beam forming network is obtained, with the separation of direct measurement errors and methodological errors associated with the use of the results of preliminary calibration of the measuring system and the restoration of the amplitude-phase distribution.

The results obtained can be used in the construction of a device designed to measure and restore the amplitude-phase distribution of linear antenna array and assess its resulting measurement errors of this device.
