| Abstract: | LFMCW radar is capable of detecting subsurface anomalies by using linear sweep frequency transmission of a periodically repetitive continuous FM signal. However, limitation of traditional FFT algorithm confined the precision. In this paper, the MUSIC algorithm is given to improve the resolution and get more precise result, which has been proved by computer simulation. A comparison is made with experimental data. |
