摘要
线性调频连续波雷达通过周期性的发射扫频信号来探测地下的异常体。但是,由于经典FFT方法固有的局限性,限制了其分辨率的进一步提高。文中介绍了MUSIC方法,通过计算机模拟表明,该方法相比FFT有更好的分辨率和较精确的结果。
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.
