Variable modulating method is used to solve the antinomy between the measuring range and accuracy. Frequency mixing is adopted to reduce the frequency of the signal  which can lower the requirement for hardware. The high ranging accuracy is achieved by way of Fast Fourior Transform (FFT) using digital signal processor and error correcting factor. Experiment results indicate that using digital signal processing method can reduce the influence of surroundings and hardware system  and obtain high ranging accuracy. 2010 IEEE.
