Abstract : This report describes the past year's research efforts (October 1993-September 1994) in the design, development and construction of an optical processing system to directly digitize and transport shipboard antenna signals to below deck. The electro-optical guided wave analog-to-digital converter directly digitizes the antenna signals and is based on preprocessing the signals with a symmetrical number system (SNS) to achieve both an 8-bit design and a 14-bit design. The status of the hardware construction is described (8bit expected completion - March 1995, 14-bit expected completion - July 1995). Using time division multiplexing (TDM) techniques, an optical digital link transports the bits over fiber to the receiver below deck.
