MATLAB Implementation of FMCW Signal Simulation

The FMCW simulation program serves as an essential educational tool that enables students to gain deeper insights into Frequency Modulated Continuous Wave radar technology. This implementation includes MATLAB code for generating linear chirp signals using the phased.LinearFMWaveform function, configuring key parameters such as bandwidth (e.g., 4 GHz), sweep time (typically 50 μs), and sampling frequency. Through this simulation, learners can explore FMCW operating principles including beat frequency calculation through mixing operations (transmit_signal.*conj(receive_signal)), range determination using the formula Range = (c*beat_freq*T_sweep)/(2*Bandwidth), and velocity measurement via Doppler processing. The program demonstrates practical scenarios with multiple target simulations and includes data parsing techniques using FFT-based frequency analysis with proper windowing functions. The simulation package provides annotated code examples showing how to implement dechirping algorithms, process intermediate frequency signals, and visualize results through range-Doppler maps using spectrogram functions. These hands-on examples help students master the complete simulation workflow from parameter configuration to result interpretation, making it highly recommended for anyone studying FMCW radar systems to strengthen both theoretical understanding and practical implementation skills.
