dc.description.abstractIn today’s society, the rate of development of sensory units in vehicles is increasing rapidly. This is a result of the autonomation of vehicles becoming increasingly more common. RADAR sensors are used in these autonomous vehicles, and due to safety, the RADAR sensor needs to be able to detect multiple different objects in front of the vehicle while driving. This paper presents a method to detect and approximate the distance of objects in a controlled environment using FMCW RADAR technology. FMCW has multiple advantages to pulsed radar including being able to detect closer objects and not needing to be turned off during ranging. The ranging of targets was done with a frequency difference of the echoed signal and the direct signal between one transmitter and receiver module. It was found that multiple objects could be detected and the distance of them could be approximated in a single measure ment. The accuracy of the approximation was 10.1 meters of the measured distance due to the limited sample rate, which impedes resolution. The method presented in this paper works as a proof of concept that an FMCW RADAR system is possible by using the ADALM Pluto SDR module. However, for this system to be implemented in any real-life scenarios the sample rate needs to be increased which would lead to a better resolution and therefore a better approximation of the distance to a target.
