Abstract :
For the purpose of accurately and quickly level tracing of bulk solid material, a new 24GHz FMCW radar measurement system with fast frequency Improved Phase-Differential estimation algorithm on platform of TI DSP 28335 and the low cost multiplier frequency VCO and mixer is realized, Three kinds of the fast tracing algorithm, Improved CZT algorithm, Improved ZFFT algorithm and the new Improved phased-difference algorithm(IPDA) is compared for the real time and accuracy. The results show that the IPDA is more suitable for the measurement of bulk solid material, and can be higher accuracy and faster speed.
