Summary/Abstract: This study explores the role of signal processing in FMCW (Frequency Modulated Continuous Wave) radar systems for determining parameters such as distance and velocity. The paper discusses the algorithms used for these measurements, emphasizing both the technology's principles and its applications. The primary objective is to identify and implement the necessary algorithms to calculate distance and velocity with FMCW radar, focusing on signal processing techniques. FMCW radar emits continuous waves that travel through space and are reflected by objects encountered in their path. Operating in high-frequency bands, typically in the GHz range, this radar type requires a minimum frequency to detect small, slow-moving, and low radar cross-section (LSS) targets, such as those in the X band. The proposed radar system is designed with a block diagram, which is analysed and simulated using Simulink and MATLAB environments. The paper concludes with the presentation of the simulation results and identifies the optimal version derived from the simulations.
