Abstract
A total power radiometer is presented for monitoring of the stratosphe ric ozone spectral line at 110 GHz. Special features such as a cooled planar Schottky mixer as the front end and efficient reduction of stan ding waves in the quasi-optics, are discussed in detail. The noise tem perature of the receiver is 530 K (SSB), and the total bandwidth of th e receiver is 1 GHz. A dual acousto-optical spectrometer is used for t he signal detection.
