However, the formula for the range resolution is derived to be c/2B in the literature, even from Infineon itself : Infineon FMCW RADAR Digital Signal Processing Where does the formula applied in the Development Kit arise and where does the additional factor of 2 in the denominator come from ...

TheradarTransceiveruses a rectangular waveform by default, but FMCW waveforms are more common in automotive radars. Attach an FMCW waveform to theradarTransceiverwith its waveform parameters set to achieve the same range resolution as was used by the default rectangular waveform designed for ...

The transmitting signal of Linear Frequency Modulation Continuous Wave (LFMCW) radar has two nonideal parameters: sweep nonlinearity and power undulation. They make the practical range precision and range resolution of LFMCW radar decrease. This paper an
advantages such as enhanced distance resolution, direct velocity detection via the Doppler effect, and imperviousness to sunlight glare and interference. But the technical complexity of precisely controlling narrow-linewidth frequency-agile lasers has so far prevented the successful parallelization of FMCW ...
