In general, the IR-UWB radars offer a slightly better accuracy and higher SNR in comparison to FMCW radar. However, each radar system has its own unique advantages, with IR-UWB exhibiting fewer harmonics and a higher SNR, while FMCW can combine the results from each channel.

Frequency-modulated continuous-wave (FMCW) synthetic aperture imaging sensor (SAIS) combines FMCW technology and SAIS techniques which makes a lightweight, high-resolution, and cost-effective imaging sensor. FMCW SAIS systems are going to play an important role in airborne and spaceborne earth observation fields. However, the stop-and-go approximation used in conventional pulsed SAIR (e.g ...
Thus, an FMCW radar system has the advantage of having lower transmitting power and cost than a traditional pulse radar system. The FMCW radar for an automobile is allocated both 77 GHz and 79 GHz bands, and their maximum allowed bandwidths are 1 GHz and 4 GHz, respectively.

yInternational Research Centre for Telecommunications-transmission and Radar, Delft University of Technology, The Netherlands AbstractŠOne of the advantage of Frequency Modulated Continuous Wave (FMCW) radars is the relative low required sampling frequency even when transmitting high bandwidths. Non-Contacting Radar. NCR transmitters use either pulse radar or frequency modulated continuous wave (FMCW) techniques to perform measurements. Pulse radar sends one microwave pulse at a time and waits for the return signal, timing it to determine the distance to the surface where it was reflected.
Thus, in FMCW radar, range is proportional to beat frequency2. Hence, by measuring the spectrum of the beat signal, a 1-D down-range map of target radar reflectivity vs. range, called the range profile, can be obtained. The block diagram of a FMCW transceiver in Figure 5 shows how this is implemented. The beat signal is generated using a 3mixer ... The proposed radar system has the capability to obtain both absolute ranges and tiny motions of targets by switching between the FMCW mode and the Doppler mode through an onboard microcontroller. The cost and hardware complexity of the proposed radar system have been reduced by utilizing the audio card of a laptop to sample the baseband signals.
An FMCW radar system, with its continuous measuring signals, is capable of good range resolution, often as fine as 0.5 m. A pulsed radar system, on the other hand, is not quite as good on range resolution. It typically suffers a large "blind spot" in front of the radar of 50 m or more, resulting in poor range resolution. ...May 29, 2020 · Since FMCW constantly builds up radar return energy (vs. a single “main bang” pulse), this system provides target detection superior to pulse radars while transmitting at far lower energy levels.
