A SPECTRAL INVERSION ALGORITHM FOR GPR SIGNALS OF THIN LAYERS
探地雷达薄层信号的谱反演算法

In order to extract information including thin layer's position and thickness,from reflected wave data of Ground Penetrating Radar(GPR) in multi-layered situation,a spectral inversion algorithm realized in frequency domain is presented.Through analysis of electromagnetic wave propagation in multi-layer media,generalized reflection coefficients are derived.After dividing the coefficients into pairs followed by decomposing the pairs into even and odd components,a cost function is established to connect reflec...
