Background technology
GPR is a kind of electromagnetic wave detection skill utilizing high-frequency impulse electromagnetic wave Underground geologic structure and feature
Art.It uses a pair antenna to be operated, and launches sky alignment underground medium and launches high frequency, broadband laser pulse electromagnetic wave, electromagnetic wave
Reflection and transmission is there is when running into electro permanent magnetic difference separating surface in underground medium communication process；The electromagnetic wave of reflection passes earth's surface back
Received by reception antenna；And then grind by analyzing the time lag of reflection electromagnetic wave, same to phasic property, similarity and wave character
Study carefully geologic body.
Suitably choosing the distance launched between antenna and reception antenna can make the echo-signal from target strengthen.Existing
Document shows, the selection of antenna distance S should make the deepest target relative to reception antenna and subtended angle is critical angle the 2 of transmitting antenna
Times, i.e. antenna distance S refers to formula (1) result of calculation and chooses.
In actual measurement, the inconvenience of work on the spot can be increased owing to strengthening antenna distance and resolution can be made to reduce, therefore
The antenna distance selected is usually less than this numerical value, often takes about 1/5th of depth capacity.Although but having theoretical formula
Computation and measurement parameter, but owing to the geological condition of each department varies, add the existence of other interference factors, so in reality
Border operating process is wanted the most rule of thumb data select several groups of different parameters to carry out comparison and detection, choose according to Detection results

The method of work of GPR generally has two kinds: the widest horn cupping and profile method.
Wide horn cupping has two kinds of different modes, and the first is to launch antenna to be fixed on a fixing point of survey line, receives
Antenna moves along survey line, and measuring point is the position of reception antenna.Second method is also called CMP method, keeps launching antenna
Motionless with the central point of reception antenna, it is gradually increased the spacing sending out, receiving antenna, measuring point is the midpoint sending out, receiving antenna, but corresponding
Different transmitting-receivings away from.Therefore, the spacing between dual-mode antenna can not keep optimum distance, so can inevitably produce bigger
Deviation.
Profile method be by transmitting antenna and reception antenna with constant spacing along the synchronization-moving a kind of metering system of survey line, send out
Penetrate antenna and reception antenna moves simultaneously and obtains once record the most afterwards.But the gap ratio generally, sending out receipts antenna is visited
Depth measurement degree is little many, and the distance between dual-mode antenna is frequently not optimum distance, so also can produce relatively large deviation.
