Abstract :
The range estimation variance Cramer Rao lower bound (CRB) of the frequency modulated continuous wave (FMCW) level radar is derived first. The CRB does not only point out the best range estimation performance the FMCW radar can achieve, it also indicates that the best performance can only be achieved by means of measuring the phase of the beat-note signal. Then the range estimation accuracies of some FFT-based range estimators are studied through computer simulation and are compared with the CRB
