【摘要】 为了研究结构物的不连续性,通过对相干数据体多道C2和多道C3算法的对比研究,将这两种算法应用于检测数据的成像来诊断结构裂隙的分布。模型数据和实际检测数据的计算结果表明:C2、C3相干算法用于裂隙检测具有较强的抗噪声性能和良好的分辨能力;特别是C3相干算法比C2相干算法在横向分辨方面更具有优越性,这也说明C2、C3相干算法是检测地质结构、公路和桥梁不连续性和缺陷的一种有效方法。更多还原

【Abstract】 In order to study the discontinuity of geological structure,the C3 coherence algorithm was compared with C2 algorithm.The detection data were analyzed by the two kinds of coherence algorithm to diagnose the crack distribution of geological structure.After the model and practical detecting data computation,the results show that C2 and C3 coherence algorithms have higher resolution power and better robust to noise,but the lateral resolution power of C3 coherence algorithm is higher than the resolution power of C2 algorithm,they are valid methods for detecting discontinuity and defect of geological structure,road and bridge.7 figs,6 refs.更多还原
