Waveform-resolved, bathymetric lidar applications demand high performance analog-to-digital converters (ADCs) to meet the demands of the high bandwidth, large dynamic range signals which are typical for coastal mapping applications. In this paper, the Agilent M9703A digitizer is evaluated with this criteria in mind and found to be an excellent candidate. Furthermore, the customizable FPGA firmware...
Airborne bathymetric lidar (Light Detection and Ranging) systems measure the optical path (range and angle) between the sea surface and the seafloor. Lidar achieves this measurement by firing a laser from an aircraft and calculating the range based on the speed of light and the time it takes for the laser pulse to return. Measurements of photoelectrons at the photocathode of a returned laser pulse...
