Abstract: An FMCW radar level meter has an RF signal processing module, an intermediate frequency (IF) signal processing module, and a computation and display module. A signal generator of the RF signal processing module generates a first RF signal, which is radiated by an antenna to a measured object. The antenna received a second RF signal reflected by the measured object. The IF signal processing module processes the second RF signal and compares the first RF signal with the second RF signal. The computation and display module calculates and displays a distance between the FMCW radar level meter and the measured object. Using the RF signal processing module and the IF signal processing module to process the second RF signal, the issues of noise and temperature coefficient shift can be resolved.
