Abstract :
The influence of interchannel and intrachannel non-identities on digital antenna array characteristics is studied. Non-identities are random amplitude and phase excitation errors of receive/transmit modules. Cases of fast and slow fluctuations of random errors are considered. Variation frequency of fast fluctuations is much greater than scanning frequency. Variation frequency of slow fluctuations is much less than frequency of scanning.
