Abstract :
Summary form only given. The results of two-tone frequency-modulated (FM) laser light scattered off a target to look at atmospheric absorptions are presented. The results are a first-time demonstration of the two-tone FM measuring technique used for monostatic (single-ended) applications involving diffusely scattering targets.
