Abstract

An all fiber linear frequency modulated continuous wave (FMCW) coherent laser radar system is under development with a goal to aide NASA's new Space Exploration initiative for manned and robotic missions to the Moon and Mars. Linear FMCW lidar has the capability of high resolution range measurements, and when configured into a multi-channel receiver system it has the capability of obtaining high precision vector velocity measurements. Precision range and vector velocity data are beneficial to navigating planetary landing pods to the pre-selected site and achieving autonomous, safe soft-landing. This paper discusses the design of a second generation prototype system under development at NASA Langley Research Center and presents preliminary performance data obtained from field experiments.
