数据采集速度是步进频率连续波（SFCW）雷达固有的问题，这可能会阻碍该技术的进一步使用和发展。我们提出了一个新兴的范例称为压缩传感（CS）来克服这个问题。在CS中，可以仅基于低于奈奎斯特速率的几个样本精确地重构信号。因此，可以显著地提高数据采集速度。提出了一种具有高捕获速度的SFCW探地雷达的设计方案。通过单周期波形仿真和矢量网络分析仪在某探地雷达靶场的实测，验证了该系统的实用性。
Data acquisition speed is an inherent problem of stepped-frequency continuous-wave (SFCW) radars, which may discourage further usage and development of this technology. We propose an emerging paradigm called compressed sensing (CS) to overcome this problem. In CS, a signal can be reconstructed exactly based on only a few samples below the Nyquist rate. Accordingly, the data acquisition speed can be increased significantly. A novel design of an SFCW ground-penetrating radar (GPR) with high acquisition speed is proposed and evaluated. Simulation by a monocycle waveform and actual measurement by a vector network analyzer at a GPR test range indicate the applicability of the proposed system.
