Xiong Zhangliang, Shan Ning, Shi Xiang-quan, Lei Bian, Wei Wang · 2006
In view of the advantages of the Sine plus Noise FMCW radar over short range, in this paper, we presented a novel liquid height measuring system based on it. The principle of this system is analyzed in detail. Considering the liquid to be measured usually with high volatility, temperature, pressure, causticity or toxicity, we utilize trihedral corner reflector floating on the liquid to enhance the accuracy of the measurement. The numerical simulation and the results of on-the-spot survey both validate the affectivity of this kind of liquid height measuring system. Key words: Random noise radar, liquid height measuring 1.
