| 摘 要： | 考虑频散介质的电磁波传播,采用Cole-Cole公式建立频散模型。只考虑介质的介电常数随外加电磁场频率的变化,采用高密度采样滤波算法,模拟层状介质的雷达响应,从中可以看出频散介质对雷达波的衰减影响。

| Abstract: | To study propagation characteristic of radar wave in adispersive medium,the dispersive is established by Cole-Cole formula.Only considering the permittivity varies with frequency,using high density sampling filter method,the GPR response of layered-medium is simulated.We can find that the dispersive medium make of GPR wave decrease. |

| Keywords: | GPR dispersive medium permittivity high density sampling filter |
