Abstract: Broadband coherent and incoherent interfering signals (jammers) are suppressed by using differencing and summing operations in an adaptive signal processing array composed of a plurality of signal detectors. A number of variable weight adaptive filters, equal to or greater than the number of jammers, are applied to all but one of the difference signals. The weighted difference signals are summed and subtracted from the remaining delayed difference signal for processing by an unconstrained adaptive algorithm to adjust the variable weights of the filters. The plurality of detector signals are also grouped by overlapping summing operations to produce summed signals for which all but one are applied to simple filters with the same weighting. These weighted summed signals are themselves summed and subtracted from the remaining delayed summed signal for delivery to a conditioning filter to recover the undistorted desired (target) signal.
