Abstract
Millimeter-wave radiometers are being used in remote sensing of stratospheric trace gases. For constituents with relatively strong spectral lines (several K), for example, ozone and water vapor, a total power radiometer with a simple load-switch calibration technique may be sufficient. If the spectral lines are weaker, and the signal to noise ratio is smaller than 10-4, a balanced calibration technique should be applied. Unfortunately, this can not easily be realized in the millimeter-wave region. Therefore, a quasi-balanced noise source in the atmosphere itself is planned.
