ABSTRACT:
An adaptive signal processor (100) utilized with a receiving system (10) in a non-stationary environment having a receiver element (12) for receiving a composite signal comprised of a desire input signal and an interference signal. The invention includes a first mechanism (102) for modulating the composite signal to provide a plurality of modulated signals and to generate a plurality of synthetic channels (104). A second mechanism (126) is provided for calculating and applying a plurality of adaptive weight values to the modulated signals in the synthetic channels (104) to provide a plurality of time varying weighted signals. Finally, a third mechanism (128) is provided for combining the time varying weighted signals in the synthetic channels (104) to eliminate the interference signal from the composite signal. In a preferred embodiment, the composite signal is received by an antenna or hydrophone (12) and then digitized and stored in a memory (122). Stored digitized data is then modulated to provide modulated signals and a plurality of synthetic channels (104). Samples of the modulated signals are used as a basis to generate a plurality of adaptive weight values which are applied to the modulated signals to provide time varying weighted signals for tracking the non-stationary environment. The weighted signals are then summed to eliminate the interference signal from the composite signal.
