Investigation of errors of acoustic goniometer information-measurement systems on rocking base
Abstract
The accuracy of azimuth information measurement systems which determine the direction of arrival of an acoustic wave front is limited severely by the angular errors which occur when the device is operated on an unstable base, such as a rocking ship. The conversion equation of such a device subjected to rocking type destabilizing factors is examined and the resulting errors are estimated.
