Laser Radar Cross-Section and Reflectivity Measurements at .48, .63, and 10.6 microns

摘要

The effect of target surface and shape, on the power reflected from it, as a function of aspect angle theta, has been investigated at 0.48, 0.63, and 10.6 micrometer in a laboratory environment. In particular, at 0.48 micrometer the reflected wave amplitude was measured relative to a standard cross section target, a Lambertian Reflector. This enabled the determination of actual Laser Radar Cross Section (LRCS) values for these targets. Further, the experimental results obtained were found to agree closely with analytical predictions based on specular scattering theory. (Author)
