Chirp Waveforms and Range-Doppler in Radar Simulations

WebJun 10, 2024 · The principle behind FMCW is that you transmit a chirped signal and receive a time delayed version of it after reflecting from a target. After mixing and filtering, the resulting signal is a sinusoid at a frequency that is a function of the target's range. This frequency is known as the "beat" frequency f b. WebAn FMCW radar system transmits a chirp signal and captures the signals reflected by objects in its path. Figure 3 represents a simplified block diagram of the main RF … WebCompared to the pulsed time-of-flight method, frequency-modulated continuous-wave (FMCW) LiDAR has been proven effective in providing high-resolution distance and velocity measurements without requiring fast electronics, and is intrinsically immune to interference from ambient light and other LiDAR transmitters.
