不同中心频率天线探地雷达在古城墙病害体探测中的应用研究
摘要:探地雷达探测精度高,方便灵活,效率高,可以根据病害体类型、埋藏深度、探测精度等要求,选择不同的天线组合类型达到最优的探测效果,并且该方法在探测过程中,不会对探测目标体造成损伤,探测结果直观,是目前探测古城墙病害体最为适用的方法。通过采用100 MHz、270 MHz、400 MHz、900 MHz、1600 MHz天线在古城墙顶面、侧面进行试验,全方位探测古城墙病害体的位置、范围、深度、规模等情况,根据不同中心频率天线的探地雷达图谱,对比分析不同频率天线探测古城墙病害体的有效性、优缺点以及适用范围。
Abstract:It is high detection precision,convenient and flexible,high efficiency of ground penetrating radar;and according to the type of diseases,the depth of the burial and the detection precision,the different types of antenna combination can be selected to achieve the best detection effect.The method does not cause any damage to the detection target in the detection process,and the result is intuitive.It is the most suitable method to detect the diseases of the ancient wall at present.In this paper,100 MHz,270 MHz,400 MHz,900 MHz and 1600 MHz antennas are used to test the top and side surfaces of the ancient wall,and the locations,scopes,depths and scales of the diseaes are explored in an all-round way.According to the ground penetrating radar atlas of different central frequency antennas,the effectiveness,advantages and disadvantages,and application scope of different frequency antennas are compared and analyzed in detecting the ancient wall diseases.
