The aim of this article is to show the concept of the close vehicle warning based on Frequency Modulated Continuous Wave (FMCW) radar. The radar works at frequency 24.1 GHz with 180 MHz bandwidth and it is intended to detect cars behind a bicyclist. The implementation of the signal processing is tested in the simulation and it is realized in Field Programmable Gate Array System On Chip and with low-cost FMCW radar. The system is installed on the bicycle.
