Abstract

We report the integration of an open-source software-defined radio (SDR) receiver to detect and track in realtime harmonic radar echoes produced by a non-linear device (transponder) mounted on a very small target. We describe a series of experimental measurements that were conducted to validate the sensitivity of the receiver system. In addition, we describe the implementation of a high-speed digital signal processing and a target detection algorithm. Finally, the experimental data and the results after the signal processing for detection are presented. In particular, it is demonstrated that the platform is a cost-effective receiver solution for the detection of transponders in Harmonic radar applications, relatively simple to program and implement.
