HYDROCON ACOUSTIC IMAGING SYSTEM.
Abstract
The Litton HYDROCON system for producing a visual representation of a distribution of acoustical energy is described, and its successful performance as an image converter in an acoustical imaging system is demonstrated. Separation of targets in range (range resolution) by range gating, an important feature of HYDROCON, is also demonstrated. It is shown that the limiting factors in image definition for the configuration currently in use are the ratio of image size to grain size of the receiving mosaic, and the ratio of objective diameter to wavelength. The effective grain size has been reduced by montage techniques, but the aperture limitation requires larger 'optical' elements or shorter acoustical wavelengths. The effects of spherical diffraction pattern are shown to produce no sensible changes in the image produced by the present system.
