Baseline Issues in an Airborne 650 GHz Radiometer
نویسندگان
چکیده
We describe the effects of baseline ripple in an airborne submillimeter wave radiometer, which are caused by standing waves in the quasi-optical path. These baselines can be reduced with an improvement of the calibration loads and with a pathlength modulator. We have modelled the impact of the baseline on the retrieval of the volume mixing ratio profiles of the atmospheric constituents and we will discuss a method for the baseline removal during the inversion process.

Comparison Of Imagery From A Scanning And A Pushbroom Microwave Radiometer
The pushbroom radiometer principle has been conceived in order to avoid the mechanical scanning traditionally used in imaging microwave radiometer systems. But does a real life pushbroom radiometer actually work as predicted, producing imagery as we are used to see it from a scanner? To answer this question a 21 channel, 36.5 GHz pushbroom radiometer intended for airborne use has been designed ...
