Point Target Linear Frequency Modulated Continuous Wave (FMCW) Beat Signal Simulation

In this article, we will discuss how to perform simulation of point target Linear Frequency Modulated Continuous Wave (FMCW) beat signals. FMCW radar is a widely used radar technology that provides high-resolution range and velocity information within relatively short time periods. To better understand FMCW radar technology, we will explore the concept of beat signals and demonstrate how to simulate these signals using computational methods. Specifically, we will introduce MATLAB-based implementation approaches for FMCW beat signal simulation, including key algorithmic components such as chirp signal generation, mixing operations, and Fourier analysis for frequency extraction. The discussion will cover critical parameter selections including signal frequency, modulation slope (chirp rate), and signal-to-noise ratio (SNR) considerations. Through detailed examination of these elements, we will gain deeper insights into FMCW radar technology and its practical applications across various domains such as automotive systems, UAVs, and robotics.
