MATLAB Simulation of FMCW (Frequency Modulated Continuous Wave) Radar Range Measurement

FMCW (Frequency Modulated Continuous Wave) radar range measurement simulation using MATLAB is a technique for determining target distance. This method transmits continuously varying frequency signals and calculates target range by analyzing the returned echo signals. The core algorithm involves generating linear frequency modulation chirp signals, mixing transmitted and received signals to produce beat frequencies, and applying Fast Fourier Transform (FFT) for frequency analysis. Key MATLAB functions include chirp() for signal generation, fft() for spectral analysis, and range calculations based on the relationship between beat frequency and distance. This simulation approach is particularly valuable for understanding FMCW radar principles in applications such as traffic monitoring, UAV navigation, and object detection systems, enabling researchers to evaluate system performance and optimize parameters through programmable signal processing workflows.
