Passive sonar ML estimator for ship propeller speed

Lourens J.G. (1997)

Conference Paper

The optimal estimator in the maximum likelihood sense for the propeller speed of a ship, using underwater radiated cavitation noise generated by the propeller blades, is derived. From the result the amount of blades on the propeller can also be derived. Results obtained for real sonar data using a digital implementation of the estimator will be presented.
