Design and implementation of a 24 GHz FMCW radar system for automotive applications

In this paper, we designed and implemented a 24 GHz FMCW radar system based on FPGA and DSP. We also developed a 24 GHz FMCW radar RF module composed of a single transmitter and a single transmitting antenna array of five elements to measure distances at a high degree of accuracy for 24 GHz FMCW radar. To verify the developed radar system, a test bed was fabricated to measure the distance for every 1 mm. The experimental results show that the system is accurate to a distance of approximately 3 cm between 0.5 m and 3.4 m.
