Abstract:

A gain modulated, Dicke switched Infrared Heterodyne Radiometer IHR has been designed, developed, and tested which is capable of measuring the atmospheric absorption characteristics within a 200 MHz bandwidth about selected hyrdogen fluoride HF laser transistions between 2.7 and 3.1 micrometers. The IHR has been installed in a KC-135 test aircraft. Provisions for remote control and remote calibration were incorporated into the radiometer. The heterodyne receiver sensitivity NEP of the IHR is 1.3 times 10 to the -19th power WHz and the calculated temperature resolution delta T sub ST sub S is given for a variety of source temperatures and total transmittances alpha.
