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.
