|Abstract:||Radar systems are widely employed for surveillance of wide and remote areas, more generally, for remote sensing purposes. The recent advent of drones, together with their spreading across multiple fields, gives the opportunity to exploit the radar sensor on board of these unmanned aerial platforms. Nevertheless, whereas drone radars are currently available for military applications, their employment in the civilian domain is still limited. The present research focuses on design, prototyping and testing of an agile, low-cost, mini-radar system, to be carried on board of Remotely Piloted Aircrafts (RPAs) or tethered aerostats. In particular, the paper faces the challenge to integrate the in house developed radar sensor with a low-cost navigation board, which is used to estimate attitude and positioning data. In fact, a suitable synchronization between radar and navigation data is essential to properly reconstruct the radar picture whenever the platform is moving or the radar is scanning different azimuthal sectors. The integrated radar system is presented in terms of the adopted solutions for its design, manufacturing and implemented processing. The approach identified for the integration of radar and navigation unit is presented. Preliminary results, relative to tests conducted in pre-operational conditions, are provided and exploited to assert the suitable consistency of the obtained radar pictures. From the results, an high consistency between the radar images and the picture of the current environment emerges; finally the comparison of radar images obtained in different scans shows the stability of the platform.|
