This patent describes a signal processing system receiving detected signals from the subarray sensors of an adaptive phased array and delivering to the array data processing system an output of weighted sensor signal, the weighted sensor signals having the signal components of multiple jamming sources in the detected signals nulled and maximizing the gain of desirable components of the detected signals. The signal processing system consists of: a parallel analog combiner receiving the detected signals from the subarray sensors of an adaptive phased array, the parallel analog combiner applying a first set of output weights to each of the detected signals from each of the subarray sensors, and combining the resultant weighted analog signals into the combiner output signal, the parallel analog combiner producing the first set of output weights by combining a first set of output weight change values with its first set of old output weight values; an error generator receiving the combiner output signal and one of the detected signals which is used as a reference signal and generating an error signal; a parallel processor receiving the detected signals from the subarray sensor, the parallel processor producing a second set of output weights to the detected signals and producing the output of weighted sensor signals to the array data processing system; the processing producing the second set of output weights by combining a second set of output weight change values with its second set of old output weight values; and an algorithm circuit receiving the error signal from the error generator and the weighted output signals from the parallel processor and providing a first set of output weight change values to the parallel analog combiner, and a second set of output weight change values to the parallel processor.
