Abstract
A directional main antenna and N omnidirectional auxiliary antennas connected to each supply an m-sample batch of signals to apparatus for developing a weighting vector 2 through Batch Covariance Relaxation apparatus, which weighting vector is then used to weight the signals from the auxiliary antennas and the weighted outputs are summed with the signal from the main antenna to suppress undesired sidelobe interferences. The processor includes apparatus performing complex vector dot product multiplication, dividing apparatus, apparatus for adding or subtracting to provide the recursive updating of vectors and memories for storing the various signals between operations.
