A TAM-BP imaging algorithm in GPR application

In airborne SAR, the principle of BP algorithm is delay and sum. However, in GPR imaging, traditional BP algorithm is restricted by the air-soil interface and the conductivity property of the soil. To obtain precise objects location and reflection intension, BP algorithm must be modified in time-delay and amplitude calculation. In this paper, a TAM-BP algorithm is presented. Measurement data using the HRGPR system are provided to illustrate the performance of the TAM-BP imaging technique.
