The two types of non-contact level radar, Pulse Level Radar and Frequency Module Continuous Wave (FMCW) Level Radar have been widley used throughout the process industry. Both non-contact “free space” techniques are low maintenance, easy to use, and effective, but FMCW is considered more ac...
FMCW激光雷达测量原理和毫米波雷达相同，都是通过频差和多普勒频移来计算距离和速度。不过FMCW激光雷达和毫...

Consider an automotive long range radar (LRR) used for adaptive cruise control (ACC). This kind of radar usually occupies the band around 77 GHz, as indicated in [1]. The radar system constantly estimates the distance between the vehicle it is mounted on and the vehicle in front of it, ...
In FMCW radar mode, nonlinear amplitude response can be corrected by precomputed code. In PD radar mode, the RX signals have been checked in the pulse width of 4 mu s with a compressed echo signal response. (C) 2012 Wiley Periodicals, Inc. Microwave Opt Technol Lett 54:474479, 2013; ...

For the sake of completeness, an up-chirp is not the only option an FMCW radar can utilize. A linearly decreasing frequency, known as a down-chirp is also possible, as drawn in the figure below. The actual signal and frequency vs time plot are shown on the left side....

This is known as the maximum unambiguous range and is related to the time required for the transmit pulse to be reflected and the meaningful radar data to be deduced. The maximum velocity an FMCW radar can detect is related to the wavelength and sweep time, as shown in Equation 2. Taking...
