Adaptive Filtering of Signals from Noise. Revision 1.

Abstract

This is a primer on extracting signals from noise. Two situations are considered: (1) a reference signal is coming directly from the noise source itself (e.g., own ship noise generated by the machinery on a ship towing a sonar array); (2) a signal which has a correlation function in time, which falls off slowly in time compared to the correlation function of the noise. A new idea in adaptive correlation, called instantaneous correlation, is introduced. Originator supplied keywords: Signal processing; Adaptive correlation.
