Software Defined Radio (SDR) technology has provided researchers and academics with the necessary input to develop and test new or existing wireless communications technologies. One of the fields in which SDR has recently been used is in the development and application of different radar techniques. Ground Penetrating Radar (GPR) has diverse applications in the detection of a great variety of materials or objects found underground. The use of this tool stands out in fields such as mining, archaeology, glaciology, military applications and lately it has gained great importance as it has great potential for the development of low-cost anti-personnel mine detectors. This article evaluates the potential of the Nutaq Pico SDR 2x2 platform for possible use in a GPR, analyzing its behavior in terms of frequency response and other technical characteristics. The versatility of the platform was evaluated in terms of the configuration of parameters such as frequency change and gain. This evaluation was made applying two different types of sweeps, one where only the frequency was varied and another where the gains and frequency were varied. As a result of these two tests, the feasibility of calibrating the equipment to carry out future tests in a wide range of frequencies was evidenced.
