Detection of Implanted Devices In Underground By Using UWB Penetrating Radar with Support of PN Code

Abstract

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