In this project a high accuracy distance measurement radar sensor is realized that allows a flexible integration into different machine tools. Based on the results from the first period of the project (2010 – 2013), the project is continued 2013 in a cooperation with the Fraunhofer FHR. With the realized radar sensor a record micrometer accuracy is achieved. Furthermore, the developed evaluation algorithms are implemented in an FPGA allowing real time measurements with measurement rates of up to 100 Hz. Successful measurements are carried out in the machine tools of various project partners.
