SIMULATION OF FREQUENCY-MODULATED CONTINUOUS-WAVE (FMCW) RADAR ANTENNAS USING MATLAB FOR ADAS APPLICATIONS

Abstract

Accurate object identification, distance estimation, and velocity measurement across diverse traffic and environmental scenarios are critical for the safe and reliable operation of Advanced Driver Assistance Systems (ADAS). Frequency-Modulated Continuous Wave (FMCW) radar has emerged as a key technology enabling these capabilities due to its robustness, precision, and adaptability in realworld driving conditions. This study presents a comprehensive MATLAB-based simulation framework for modeling and analyzing FMCW radar antennas, tailored to support ADAS applications such as Adaptive Cruise Control (ACC), Automatic Emergency Braking (AEB), and Blind Spot Detection (BSD). The proposed model incorporates antenna array topologies, beamforming techniques, and target response analysis to evaluate system-level performance under varying conditions. By simulating practical parameters such as carrier frequency, bandwidth, antenna gain, and beamwidth, the research assesses critical aspects including range detection, velocity estimation, angular resolution, and interference resistance. The results highlight how optimized antenna design and advanced signal processing strategies can significantly enhance detection accuracy and system reliability in dynamic traffic environments. Overall, this work underscores the potential of MATLAB simulations in guiding efficient FMCW radar design and development, contributing to the advancement of dependable radar solutions for next-generation autonomous systems.
