Abstract: The goal of the project is to build a low cost Doppler radar with coaxial microwave parts and to develop circular waveguide Cantenna construction. In this project 5.8GHz continuous wave (CW) signal is transmitted. The radar system is constructed by using hardware components such as Cantenna, voltage controlled oscillator, power amplifiers, splitter, mixer, and video amplifier. The entire system is powered using a 24V battery. The acquired data from the radar system is recorded by using audacity software and save as “.wav” file. This “.wav” file is processed in Matlab. The measurements are taken on the road inside the MAEU campus. The result of velocity can be viewed with personal computer (PC).
