【摘要】 针对煤矿开采过程中的安全问题以及煤矿开采超前探测的研究,设计了一种应用于煤层超前探测的探地雷达系统。通过对SDR技术与FMCW的分析与研究,将两者相结合,设计实现了一种SDR探地雷达,采集天线数据后,利用软件对其回波完成处理。测试结果表明,其可分辨多个目标物体,并具有较好的分辨能力,可应用于煤矿开采中。同时也为探地雷达功能单一化、结构大、造价昂贵的问题提供了解决方案,确保了煤矿开采安全性的同时也提高了探测效率。更多还原

【Abstract】 Aiming at the safety issues in the coal mining process and the research on advanced detection of coal mining,a ground penetrating radar system for advanced detection of coal seam is designed.Through the analysis and research of SDR technology and FMCW,combining the two,a SDR ground penetrating radar is designed and implemented. After the antenna data is collected,the echo is processed by software. The test results show that it can distinguish multiple target objects and has a good resolution ability,which can be used in coal mining. At the same time,it also provides a solution to solve the problems of single function,large structure,and high cost of ground penetrating radar,which ensures the safety of coal mining and improves detection efficiency.更多还原
