WebDownload scientific diagram The basic principle of the FMCW radar with the sawtooth shape modulation: (a) the transmitted and received signal, (b) the corresponding beat … 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.
