摘要：
Accuracy and efficiency are two important objectives of modeling ground penetrating radar (GPR) signal. Achieving both together is a driving factor for advanced research in the state of art for GPR community. Full wave model (FWM) promises great accuracy to detect layered media. However time efficiency of FWM is poor compared to other simplified models. This work presents a new plane wave model (PWM) based on simplified expression of an FWM. The proposed model is capable of detecting layered media in far field condition with great accuracy and efficiency. Based on this scheme a monostatic frequency domain GPR system is realized in laboratory environment. The model is validated by testing water layer and comparing accuracy and efficiency with an existing FWM scheme.
