dc.description.abstract | The times in fast variety, people work to always hope fast and then valid, had better can also save expense in addition, deeply the land mine attain a method opposite open to dig in the clear ditch, ground-penetrating radar to explore, obvious since quick and again save expense, in the civil engineering in carry on in the city underground open to dig to usually concern the problem of underground pipeline, if can not control a pipeline to lay position correctly in times before, will cause to construct in the engineering in the days to come last inconvenience and risk, and if adopt traditional clear ditch to open the way for digging to bring about greater influence on transportation easily, and not agree with to match an economic benefit.High Pin ground-penetrating radar deeply the land mine attain to have a high resolution, the signal repetition is high, and tests a fast advantage. So adoption fast, the economy is high of nondestructive evaluation way concert the related data take in to judge, is already the trend of future development, in order to being easily subjected to direct wave rather great influence when the time area measurement’’s analysis reflect a signal, often cause shallow layer signal easily with direct wave mutual interference and hard discretion.This research mainly experiments through the school and now experiment, understand the signal characteristic of radar wave, again through behind handle of way, improve deeply land mine to attain of signal. According to the analytical result manifestation of the experimenting of school and scene, behind handle program ability will direct wave signal with keep on the existent background noise clean, having further control to the analysis that need to be measured a thing signal and the judgment. | en_US |
