| 摘 要： | 与时域无载频脉冲体制的探地雷达技术相比，频率步进探地雷达（stepped frequency ground penetrating radar, SFGPR）具有较多优越性，但由于其工作频率是以阶梯方式步进，导致成像速度较慢。提出了一种基于压缩感知(compressive sensing, CS)的频率步进探地雷达成像算法。实验结果表明，基于CS理论构建的CS SFGPR系统具有数据采集时间短、成像速度快等特点。〖JP〗

| Abstract: | Compared to a traditional no-carrier pulse ground penetrating radar,the stepped-frequency ground penetrating radar(SFGPR) has many advantages on detection performance.Since its work frequencies increase in stepped mode,the SFGPR system has low imaging speed.A novel imaging algorithm of the CS-SFGPR system based on compressive sensing(CS) theory is introduced.The experimental results show that the CS-SFGPR system reduces the data collection time and improves imaging speed. |
