Abstract :
This paper describes the design steps in producing a GPR for deep, mainly geological and environmental investigations. A phase coded spread spectrum pulse is used with high power transmitters to an antenna array. The receiver has a real time data converter with a correlator giving 125dB dynamic range. Initial results are shown.
