与探空雷达相类似,地质雷达也是利用高频电磁脉冲波的反射实现探测的,只是它从地面或矿井下向地下发射电磁波来探测地质现象,故也称之为探地雷达。 雷达采用高频电磁波探测技术,波长短,指向性好,主要是利用传播时间的延迟精确地测量探 Similar to sounding radars, geologic radars use the reflections of high-frequency electromagnetic impulse waves to detect, except that it emits electromagnetic waves from the ground or underground to underground to detect geological phenomena, so it is also called ground penetrating radar. Radar using high-frequency electromagnetic wave detection technology, short wavelength, good directivity, mainly the use of propagation time delay to accurately measure the probe
