Automotive radar is an emerging field of research and development. Technological advancements in this field will improve safety for vehicles, pedestrians, and bicyclists, and enable the development of autonomous vehicles. Usage of the Automotive radar is expanding in car and road areas to reduce collisions and accident. Automotive radar developers face a problem to test their radar sensor in the street since there are a lot of interferences signals, noise and unpredicted situations. This thesis provides a part of the solution for this problem by designing a device can demonstrate a different speeds value. This device will help the developer to test their radar sensor inside an anechoic chamber room that provides accurate control of the environmental conditions. This report shows how to build the measuring setup device, step by step to demonstrate the people and vehicle’s speed in the street by a Doppler emulator using the wheel for millimetre FWMC radar. Linear speed system needs a large space for testing, but using the rotational wheel allow the developer to test the radar sensor in a small area. It begins with the wheel design specifications and the relation between the rotational speed (RPM) of the wheel and the Doppler frequency. The Doppler frequency is changed by varying the speed of the wheel. Control and power circuit was carefully designed to control the wheel speed accurately. All the measuring setup device parts were assembled in one box. Also, signal processing was done by MATLAB to measure the Doppler frequency using millimetre FMCW radar sensor. The measuring setup device was tested in the anechoic chamber room for different speeds. the manual and automatic tests show good results to measure the different wheel speeds with high accuracy. / Combined Radar-Based Communication and Interference Mitigation for Automotive Applications / EMC Hammer
