Abstract
In this work an innovative high speed continuous wave stepped frequency GPR has been designed and implemented with the aim of overcoming the low speed issue of wide bandwidth CW-SF GPRs. It is based on a structure combining a Digital Direct Synthesizer (DDS), a Phase Lock Loop (PLL) and a quadrature modulator (I/Q Modulator). The radar is an L-S band GPR able to scan a 1 GHz bandwidth (1500-2500 MHz) with 200 steps in 10 ms.
