The frequency f T (t) and phase F(t) of the linear FMCW transmit chirp are expressed as linear and quadratic functions of time, as shown in Figure 1. In a typical FMCW radar implementation (Figure 2
Lidar can take on several different modalities, which can be classified by their dependence on incoherence or coherence of the laser source which is used. Each of these methods uses the optical path of the target reflector to effectively modulate the envelope intensity of the detected signal.

In the latter case, the data are collected by an FMCW radar with MIMO functionality that has been designed and realized in cooperation with TNO, the Netherlands. Published in: IET International Conference on Radar Systems (Radar 2012) Article #: WebFeb 5, 2024 · Optical frequency-modulated continuous-wave (FMCW) reflectometry is a ranging technique that allows for high-resolution distance measurements over long ranges. Similarly, swept-source optical coherence tomography (SS-OCT) provides high-resolution depth imaging over typically shorter distances and hi …
WebFMCW relies on window-based sidelobe rejection to address self-interference (clutter) that is far less robust than ToF, which has no sidelobes to begin with. To provide context, a 10μs FMCW pulse spreads light radially across 1.5km range. Any objects within this range extent will be caught in the FFT (time) sidelobes.
