Parallel processor configuration for adaptive antenna arrays

A signal processing system, which operates in parallel with the outputs of sensors of an adaptive array, for quickly nulling multiple jammers. The processing system includes a set of parallel combiners and an apparatus for updating a signal weight which is applied to the sensor outputs. The parallel combiners mix a weighing function with each sensor output and provide a resultant output signal which has been cleared of interference from jamming. Part of the resultant signal is fed to the apparatus for updating the signal weighing function for further mixing with sensor outputs. The parallel operation of the combiners with each sensor output provides fast nulling effects.
