We provide services and consulting in all aspects of weather radar, with a focus on weather radar calibration. We can develop sophisticated microwave remote sensing instruments through our microwave engineering services. We combine custom-built HF front-ends with software defined radio (SDR) transmitter and/or receiver back-ends. Our service portfolio is completed by perfoming radiative transfer modeling in the microwave and infrared range in order to be able to develop complete microwave remote sensing applications.
