ADAPTIVE MATCHED FILTER FOR RADAR SIGNAL DETECTOR IN THE PRESENCE OF COLORED NOISE

摘要

A system for electromagnetic signal detection having an adaptive circuit generating a time-varying matched filter characteristic whereby the statistical properties of additive noise appearing in a receiver output may be "tracked." The statistical behavior of "colored" noise is evaluated and the matched detection filter characteristics are modified accordingly, so that detector performance for signals in "colored" noise is comparable to that achieved by an optimum invariant matched filter for signal detection in "white" noise.
