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.
