Abstract

A PC-based data acquisition, analysis, and display system has been developed for use with continuous wave (cw) lidar at NASA’s Marshall Space Flight Center (MSFC). The data system was designed around a 386SX computer with lidar data collection and spectrum estimation occurring via a high speed transient capture peripheral board slaved to a digital signal processor (DSP) peripheral board. This system was developed for use during the second survey mission of NASA’s GLObal Backscatter Experiment¹ (GLOBE II). MSFC supported two separate CO₂ cw lidars² for the experiment, one operating at 10.6μm and the other at 9.11μm.
