多次覆盖技术在探地雷达勘探中的应用(英文)
|
摘要
多次覆盖技术作为一种增强信号、压制干扰的方法,广泛用于地震勘探工作中,可以大大提高有用信号的信噪比。本文作者把多次覆盖技术引入探地雷达测量工作中,通过与剖面法作对比试验来论证多次覆盖技术在探地雷达勘探中应用的可行性及优缺点。作者根据试验资料总结探地雷达工作中雷达波传播规律、工作参数、资料处理方法,对丰富探地雷达勘探技术作了一次有益的尝试。
Multi-fold technology is widely applied in seismic exploration as a method of enhancing useful signals and suppressing noise interference to greatly increase the signal to noise ratio (S/N). The authors introduce it to ground-penetrating radar (GPR) surveys and compare the experimental results to the conventional profiling method to demonstrate the feasibility and advantages of the technique for GPR exploration. Based on the experimental data, the authors summarize the GPR wave propagation rules and the parameters of multi- fold acquisition and processing. It is proven to be a useful attempt to enrich the GPR survey technology.
