  1. The conclusions from this research include : ( 1 ) the real part mainly effects the delay time between two peaks of gpr signal, the larger the real part, the longer the delay time. ( 2 ) the imaginary part mainly affects the peak amplitude of gpr waveform except that from pavement surface, the higher the imaginary part, the lower the peak amplitude. ( 3 ) the neglect of imaginary part of dielectric will increase the analyzing error obviously when it is higher

    分析了路面結構層材料介電常數實部和虛部對電磁信號的影響,並得出以下結論: ( 1 )介電常數的實部主要影響的時延,實部越大,時延越長; ( 2 )虛部主要影響除路表幅之外的其它結構層界面的幅,虛部越大,幅越小; ( 3 )當介質介電常數虛部較大時,忽略虛部將給分析結果來明顯的誤差; 3
  2. The reflected wave will be received by the receive antenna and transferred to digital data. we can analyze the data that saved by the computer of gpr to deduce the medium ' s property, situation, location and so on. being a kind of nondestructive, untouched method, it has many advantages such as nondestructive, rapidness, simpleness and high precision, so it will have wide applications in the ways of examination, control and maintenance to road quality, especially for highway
