摘要

多次覆盖技术作为一种增强信号、压制干扰的方法,广泛应用于地震勘探工作中,可以大大提高有用信号的信噪比。把多次覆盖技术引入探地雷达测量中,通过与剖面法作对比试验论证了多次覆盖技术应用于探地雷达探测堤防隐患的可行性及优缺点。根据试验资料总结了探地雷达工作中雷达波传播规律、工作参数、资料处理方法,这对丰富探地雷达勘探技术是一种有益的尝试。
Multi-fold technology is widely used in seismic survey as a method of enhancing signal and suppressing interference,therefore it can increase the ratio of Signal/Noise(S/N).The authors of this text bring it into use in GPR survey by comparing experiment to the profiling mode,and discuss the feasibility and the advantage and disadvantage in the GPR survey applied in the hidden danger detection in dam.Based on the experiment data,the authors summarize the GPR wave propagation discipline,the parameter of multi-fold survey and processing method.It may be a useful attempt to enrich the GPR survey technology.
