Measuring Depth Profiles of Scattering in the Ocean
LIDAR (laser radar) is used for oceanographic research, and emits a short light pulse whose return echoes are digitized and analyzed to determine the composition and location of underwater objects. This requires a digitizer with high sampling speed, wide bandwidth commensurate with the pulse width, and high dynamic range. What is needed in reality is a 14-16 bit, 1 Gsample/second (Gs/s) analog-to-digital converter (ADC), which does not yet exist. Currently the program is using a 100 MHz logarithmic amplifier and a COTS 8 bit, 1 Gs/s ADC PC plug-in board. This study will validate the feasibility of employing a novel array of 12- 14 bit COTS ADCs to achieve the desired 500 MHz bandwidth with 1 Gs/s, and define a specification and detailed technical approach to Phase 2 implementation as a computer plug-in board.
