Design of A CW-SF Ground Penetrating Radar

Most of Ground Penetrating Radars (GPR) are pulsed system, nevertheless there are a number of applications for which Continuous Wave Step Frequency (CWSF) radar can be advantageous. Generally speaking, CWSF systems are more complex then pulse radar, but they can manage larger bandwidth, have larger time efficiency and better control of the band. Furthermore, power, integration time and step of each single frequency can be controlled. In this paper the authors, that work in the CWSF field since several years, are aimed to give some guidelines and a practical example of CWSF designing.
