Abstract

ATLID is a spaceborne backscatter LIDAR using a solid-state Nd-YAG laser (1.06 micrometers wavelength) and a 0.6 m diameter telescope. It is intended to fly on-board a polar platform satellite. The selected concept consists in a lightweight scanning telescope associated to a contra-rotative flywheel. A linear scanning (+/- 23 degree(s)) is used in order to achieve the required swathwidth (700 Km). The detector is a silicon Avalanche Photodiode. The instrument has been compacted to a similar volume as for currently developed ENVISAT-1 instruments. The thermal control is designed to be independent of the neighbor instruments, thus allowing ATLID to be mounted on a multi-instrument payload. A breadboarding program has been initiated for critical parts of the instrument. This paper describes the overall instrument architecture, as well as first breadboard results.
