Performance measures for adaptive antenna systems

As the desire for jamming-resistant satellite communication grows, adaptive antennas will soon enter service on satellite platforms. These antennas cancel received interference to a low level while preserving as much user coverage as possible. The specification of adaptive antenna performance has considerable subtlety. Such antennas need measures of quiescent and steady-state adapted performance, as well as the speed and quality of the adaptation. A set of measures are discussed for user coverage and jammer suppression.
