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.
