HORIZONTAL GRADIENT EFFECTS ON DIRECTIONAL ACOUSTICAL SENSORS.
Abstract
An investigation was made into the types of fixing error that would result when two passive directional sensors in one velocity medium was obtaining its fix on a target in another velocity medium. For typical velocity differences that could exist in the ocean off the U. S., this error was investigated for various values of sensor spacing and target/sensor relationships to a velocity discontinuity. Tabular and graphical results were obtained which revealed that errors could result under certain conditions and these results were predictable and could operationally be avoided. (Author)
