Research on Improving LFMCW Radar Level Measurement Accuracy

Abstract:

Article Preview

LFMCW radar have a high range measuring accuracy in theory. But in practice, the picket fence effect of the FFT transform, making the range resolution and range accuracy in the same order of magnitude, can not meet the accuracy requirements for the near range measuring . Cascade FFT method is adopted to reduce frequency space of the main lobe of echo range spectrum on the FFT with increasing the less operation .The method can greatly improve the range precision of LFMCW Radar.
