The calculation of the influence of amplitude-phase errors, failure or the random number of radiant channels on the main characteristics of antenna arrays (AA). The paper presents an algorithm for simulating the failure of elements and modules of AA based on known functions of amplitude-phase distributions. Qualitative characteristics of the orientation of the AA in conditions of the established channels, modules and the availability of errors in amplitude-phase distributions are calculated.
