Abstract
A remote sensing system includes a transmitter for transmitting an online signal and first and second offline signals toward a target. A receiver receives a returned online signal and first and second returned offline signals from the target. A processor is provided for determining (a) a first ratio based on the returned online signal and first offline signal, and (b) a second ratio based on the returned online signal and second offline signal. A filter is also provided for correlating the first ratio with the second ratio for determining whether the returned online, first offline and/or second offline signals are useable. The returned online, first offline and second offline signals are used to compute first and second concentration path lengths (CPLs) of a column of air between a target and the remote sensing platform.
