Abstract

A coherent laser radar has been constructed, using an injection locked TEA-CO2 laser transmitter which is grating tunable from 9-11 μm, to measure tropospheric aerosol backscatter coefficients as a function of altitude and wavelength. A standard hard target is desired to aid in the calibration of the responsivity of the coherent lidar system and to allow quantitative comparison of our backscatter data with data taken by others. An ideal target would be easy to fabricate, reproducible, durable, and have a well-known bidirectional reflectance-distribution function (BRDF)1,2 at all wavelengths in the spectral region of interest.
