Method and system for estimation and extraction of interference noise from signals

摘要

A system for reception of electromagnetic waves in spectrum in which interference occurs comprising at least one transmitter; at least one receiver configured to receive the received signal; a first memory portion configured to store data relating to a point target response; a spectrum estimator configured to estimate the frequencies at which interfering signals occur; at least one processor configured to generate an estimation of the interfering signals at the frequencies estimated by the spectrum estimator; a second memory portion operatively connected to the at least one processor configured to store the estimation of the components of the interfering signals; the at least one processor configured to substantially reduce or eliminate radio frequency interfering signals from the received signal utilizing the point target response and the estimation of the interfering signals; and a method to substantially reduce or eliminate radio frequency interfering signals from for image data.
