Abstract: A system and method are provided for separating ocean surface reflected light, atmosphere and ocean scattered light, and anomalous objects in multispectral ocean imagery. The method begins with input image data including a plurality of pixels. The pixels are analyzed and exceptionally “red” pixels are eliminated from further processing. A processed image is produced by subtracting the estimated reflected and scattered light. The output image can then be provided for human analysis or further automated computer processing to locate anomalous objects on or below the ocean surface.

Abstract: A neutron detector is disclosed which uses the moderating material as the structural support for the neutron detector element. A thin metal liner is affixed to the inside of the plastic moderating material encasement for containing a neutron detecting gas. A high voltage supply is connected to an electrical conductor which extends between the ends of the encasement and serves to furnish output pulses to a pulse counter upon the occurrence of ionization of the counting gas in response to neutron flux through the volume of the detector.
