Paper Abstract

Measurement of infrared radiation for the detection of air turbulence such as Low Altitude Wind Shear (LAWS) and high altitude Clear Air Turbulence (CAT) is pursued. CO2 infrared absorption and re-emission in the 13p to 16p region is exploited. A laboratory sensor instrument is being developed with cryogenically cooled mercury cadmium telluride linear array in the scanning mode with multiple spectral filters to cover the 8p to 12p transmission band as well as the 13p to 16p CO2 absorption band. A future option of utilizing an uncooled planar pyroelectric array in the staring mode is contemplated. Current effort is concentrated on developing the instrument as well as analysis and simulation. It is anticipated that a field demonstration unit will be available in the summer of 1991.
