The technique of inverting a single-ended lidar return to obtain range-dependent atmospheric extinction coefficients requires an assumption concerning the relationship between the volumetric backscatter and extinction coefficients. By comparing the p

Airborne measurements of mid and far infrared (IR) sea radiances were obtained using a calibrated dual-wavelength band thermal imaging system (AGEMA 900). The measurements were used to evaluate a sea radiance model which is based on the Cox-Munk wave

For the past twelve years, a coordinated tri-service effort has been underway in the United States Department of Defense to provide an atmospheric effects assessment capability for existing and planned electro-optical (E0) systems. This paper reviews

This Letter demonstrates that there is a link between the double ended inversion method and the forward or the reverse inversion method, with a known relationship between extinction and backscatter.

A solution of the single-scattering lidar equation requires a relationship between the coefficients of backscatter beta(r) and extinction sigma(r) to be of the form beta(r) = C2sigma(r)k, where C2 and k are parameters independent of range r. The sens
