Abstract:
1. A remote sensing system comprising: a transmitter that transmits an online signal and first and second offline signals toward a target, a receiver that receives a returned online signal and first and second returned offline signals from the target, a processor configured to determine (a) a first CPL (concentration path length) value based on the returned online signal and only the first offline signal, and (b) a second CPL value based on the returned online signal and only the second offline signal, and the processor configured to determine a first CPL mean and a first CPL standard deviation, based on a predetermined number of first CPL values, the processor configured to determine a second CPL mean and a second CPL standard deviation, based on a predetermined number of second CPL values, a filter that correlates the first CPL value and the second CPL value with (a) the first CPL mean and the first CPL standard deviation and (b) the second CPL mean and the second CPL standard deviation, respectively, for determining whether the first and second CPL values are useable.
