一、引言随着国民经济的发展,日益迫切地需要一种能探测地下埋藏物和地层结构的设备.如市政建设需要查明地下管道(水管,煤气管,电缆等)的分布,建筑施工前对地层结构的了解,公路下的空洞的探测等.这类探测的深度不大,一般在10米以内,但要求有很高的分辨力. 利用辐射为手段能有效地探测地层中的物体或地层的结构.目前有四种已知的辐射能穿入地层,即中微子,宇宙射线,地震波和电磁波.前两种不易控制,
I. INTRODUCTION With the development of the national economy, there is an urgent need for a device that can detect underground burial objects and formation structures, such as municipal construction needs to identify the distribution of underground pipelines (pipes, gas pipes, cables, etc.) The understanding of the structure of the strata, the detection of the hollow under the road, etc. The depth of such detection is not large, generally within 10 meters, but requires high resolution.Using radiation as a means to effectively detect objects in the formation or The structure of the stratum There are currently four known types of radiation penetrating the formation, namely neutrinos, cosmic rays, seismic waves and electromagnetic waves.The first two are not easily controlled,
