N. Gopalsami et al., MILLIMETER-WAVE MEASUREMENTS OF MOLECULAR-SPECTRA WITH APPLICATION TOENVIRONMENTAL MONITORING, IEEE transactions on instrumentation and measurement, 45(1), 1996, pp. 225-230
This paper presents results of mm-wave spectral properties of chemical
s in the 225-315 GHz frequency range at ambient atmospheric pressure.
The effect of pressure broadening of the spectral lines is determined
by both experiments and theoretical simulation, Subsequent to the labo
ratory measurements, the proof of the principle of the open-path monit
oring of airborne chemicals was tested by using a monostatic swept-fre
quency radar system.
