ABSTRACT:
An adaptive sidelobe blanker uses the covariance matrix used to form an adaptively nulled main channel to generate an adaptively nulled version of an omnidirectional antenna pattern. Individual antenna control includes sampling, digitizing, and storage of an antenna signal. Complex antenna weights manipulate the antenna signals in both the main channel and the blanker channel to provide desired steering of the antenna nulls. The adaptively nulled blanker channel is compared to the adaptively mulled main channel to determine if a received target return is a main beam target or a sidelobe target.
