Abstract
A wideband interference suppression system comprises at least one signal conditioning device receiving at least one input signal having a signal of interest portion and an interference signal portion, wherein the at least one signal conditioning device is adapted to provide selective, independent, and variable control of one of a phase, a time delay, an amplitude, a radio frequency signal division, and a radio frequency signal summation of the at least one input signal to produce a modified signal. A tunable cross correlator receives a signal representative of the modified signal and is adapted to estimate one of an amplitude, a time delay and a phase delay parameter of the interference signal portion and to generate a control logic signal therefrom, wherein the control logic signal is received by the at least one signal conditioning device for independently and selectively activating and adjusting the various components thereof to suppress the interference signal portion.
