1 October 1991A 625 - 650 GHz heterodyne receiver for airborne operation
A heterodyne receiver has been developed for operation in the frequency range 625-650 GHz. The goal of the ongoing project is to provide an effective tool to study upper atmospheric trace gases. The receiver is designed to operate on the research aircraft FALCON at flight altitudes of 10-12 km. Receiver performance and tuning capability were tested during a first flight campaign in April '91, with measurements of stratospheric ozone (647.8 GHz) and HCl (625.9 GHz).
