Direct detection radiometer, DDR
Omnisys Instruments has been awarded the ESA contract for a Direct Detection Radiometer.
Direct detection means that the 243GHz signal is not down-converted with a mixer and then detected. Instead we have a high frequency low noise amplifier, high frequency filters and high frequency detector diodes working direct on the 243GHz signal.
Omnisys is prime for the contract but the radiometer is designed and built in collaboration with Chalmers, IAF Fraunhofer and ACST Gmbh.
