RAPID v3

One Platform for all Sensors

The control and analyzing unit of the 24, 60 or 122 GHz radar sensor RAPID v3 is based on a micro controller from the Cortex M4 family. The RAPID v3 sensor offers much flexibility in hardware assembly. Using this approach, cost-efficient variants can be realized for applications which require moderate distance measurement accuracy. At the same time, high-precision measurements are also possible by changing certain components on the radar circuit board and using highly-sophisticated signal processing.
