The imposition of a curved phase characteristic reduces the peak amplitude of the waveform . 曲线形相位特性减小了波形振幅峰值。
Peak to peak amplitude 峰峰振幅
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 分析了路面结构层材料介电常数实部和虚部对雷达电磁波反射信号的影响,并得出以下结论: ( 1 )介电常数的实部主要影响雷达反射波的时延,实部越大,时延越长; ( 2 )虚部主要影响除路表反射波幅之外的其它结构层界面的反射波波幅,虚部越大,反射波幅越小; ( 3 )当介质介电常数虚部较大时,忽略虚部将给分析结果带来明显的误差; 3
