A signal disambiguation algorithm for use in multi-beam receivers

Receiver systems designed to simultaneously act on multiple wideband signals of interest must be able to differentiate between the different wideband signals of interest in the electromagnetic environment. Separation of interference sources from signals of interest relies on a system having either spatial or spectral diversity to detect and remove the interference sources. If interference sources are co-located in either frequency or space with the signal of interest classical techniques fail to resolve the signals of interest within the interference. This paper presents a new signal disambiguation algorithm with both spatial and spectral diversity that is able to act in a congested electromagnetic environment and distinguish between multiple signals of interest while rejecting noise co-located in frequency and/or space with the signals of interest.
