Precipitation measuring device e.g. for weather-based control of systems in motor vehicle or building

摘要

The device uses a radar sensor (1) with a transmitter and a receiver operating in the microwave or radar wave ranges. An evaluation device performs frequency analysis. The Doppler shift between the transmission and reception frequencies maybe analyzed. The evaluation device may evaluate the received signals with respect to the signal shape of individual signals. An Independent claim is included for a device or electrical or electronic systems in vehicles, buildings, etc.
