众所周知,雷达一般用于探测空中、地面和海面目标,经过几十年的发展,上述雷达技术已经非常成熟,但雷达应用于探测地(水)下却是一项新科技。然而在经济建设和军事上非常需要能方便地探测地面下情况的技术手段。前一时期探地技术和手段主要有“多光谱”和“红外线”两种,但它们有严重缺陷,一是只能探测浅层地下情况;二是只能获得地下目标某一平面资料,无法获得立体资料。为解决这些难题,人们开发了用电磁波探地。
As we all know, radar is generally used to detect air, ground and sea targets. After decades of development, the above-mentioned radar technology has been very mature. However, the application of radar to the ground (water) is a new technology. However, there is a great need in the economic construction and military fields for the technical means to easily detect the situation under the ground. In the previous period, there were mainly two kinds of exploration techniques and methods: “multi-spectrum” and “infrared”, but they had serious flaws. One was that they could only detect shallow underground conditions and the other was that they could only obtain some underground targets Flat data, unable to obtain three-dimensional information. To solve these problems, people have developed the use of electromagnetic wave exploration.
