Abstract: The effect of malfunctions of AESA channels placed
on the spacecraft on the radiation characteristics is considered. The form of
the relevant patterns and the results of the quantitative analysis of the
radiation from failure AESA channels is shown. Randomly selected N channels,
which were consistently turned off, were used in calculations. Zero excitation
amplitude of emitter was considered as turning off, and it was assumed that the
emitter is loaded. Calculations were made for phase-locked AESA, in a given
direction in the azimuthal-elevation coordinate system with the mutual
influence of radiators and errors in the initial phase of installation at the
output of the gain.
