Large Aperture Multi-Dimensional Laser Radar Testbed

Abstract

A 39 cm aperture multi-dimensional laser radar has been built and made operational. This sensor acquires pixel registered range, Doppler, 3-5 micrometer passive, and visible passive data. Range is digitized at 200 MHz for .75 m range resolution. Doppler is resolved to .5 mph with a SAW spectrum analyzer. Multi-dimensional images can be taken with an angular resolution of from 33 microrad to 1 millirad. Image size and data flow are controlled by a minicomputer. The technical details of this laser radar testbed are the subject of this report. Keywords: Laser radar; Range measurements; SAW spectrum analyzer; Doppler measurement; Passive detectors; Surface acoustic wave devices.
