摘要
雷达波的传播速度随介质而变 ,这给准确定位探测目标带来了一些困难 ,因为目标深度取决于速度与讯号反射时间的乘积。但另一方面 ,利用速度变化与介质的关系 ,反过来可以推断介质的物质架构。作者结合实用例举了 7种求速度的方法 ,以供使用探地雷达的同行们选用。
The propagation speed of the radar wave varies with media. This causes some difficulties in the accurate locating of the detection object, because the object depth depends on the product of the speed and the signal reflection. On the other hand, however, therelationship between the speed variation and the media can be used to infer the material framework. With the application in mind, the author enumerates seven sorts of speed-calculating methods for colleagues reference.
