Method for correction of inter-channel and quadrature non-identities of receiving channels of digital antenna array (DAA) that is in fact that for calculation of integral coefficients of correction for each r-th receiving channel of DAA one performs application of a control harmonic signal to the inputs of the antenna array, with calculation of integral coefficients for each r-th receiving channel of DAA. As voltages of received signals that are used for calculation of integral coefficients of correction for each r-th receiving channel of DAA and for direct correction of received signals one uses results of additional strobbing of readings of analog-digital transformers (ADT) through partial adding output codes of ADT in given time intervals (strobes).
In this article are analyzed one-cascade and multicascade I/Q-demodulators with two channels.
