Abstract
In this study, the design of a low-cost frequency-modulated continuous wave (FMCW) radar system at C-band using commercial off-the-shelf (COTS) components is presented. The proposed radar system consists of low-cost surface-mounting devices and monolithic ICs on a multi-layer FR4 PCB for system integrity. The Tx/Rx antennas (Cantennas) were fabricated with commercial cans based on waveguide dominant mode analysis. The proposed radar system is connected to the Arduino UNO platform, which transfers the received analog backscattered RF signal to MATLAB to display a range versus time intensity (RTI) plot. The designed radar has a maximum detection range of 56.3 m.
