Paper Abstract

The MR-CATSI combines the latest ABB Bomem MR spectro-radiometer technology and software with the concepts used in the design of the ABB and DRDC CATSI instrument twelve years ago. This instrument is a Fourier transform spectro-radiometer with dual input beams. It is a passive, stand-off sensor. One input port can be directed to the area to be interrogated while the other input beam can be pointed at the background. The instrument automatically measures the difference of spectral radiance between the target and the background, hence achieving a suppression of the background signal. The resulting measurement is the unique spectral signature of the target. The system includes a software module to control the instrument and the acquisition parameters, a module for the radiometric calibration and a module to perform the identification and quantification, in real time, of various gases. Overview of the design and results from field trials will be presented. This includes recent measurements of a number of gas plumes.
