摘要：Ground Penetrating Radar (GPR) is a method for estimation of underground structures by sending andreceiving electromagnetic. With Ultra Wideband (UWB) signal, GPR is expected to improve resolution for detection ofobjects in underground. But there are problems that attenuation of waves from deep objects and confusion of wavesfrom different objects. We propose a signal processing for UWB GPR to improve detectionaccuracy by applyinginterference cancellation technique for wireless communication. To obtain gains, we use a long transmitting signal withPN codes remain in low instantaneous power. Then estimating and cancelling reflect waves from received signals, wedetect objects recursively. Position estimation of medical implanted devices can be also improved by using thetechnique. With comparing GPR and medical devices, we study a signal processing for position estimation for objectsin dielectric substances.
