  In the incoming years, the low-aerial space will be crowded by unmanned
aerial vehicles (UAVs), which will be providing different services. In this
expected context, an emerging problem is to detect and track unauthorized or
malicious mini/micro UAVs. In contrast to current solutions mainly based on
fixed terrestrial radars, this article will put forth the idea of a dynamic
radar network (DRN) composed of UAVs able to smartly adapt their
formation-navigation control to best track malicious UAVs in real-time, with
high accuracy, and in a distributed fashion. To this end, some technological
solutions and the main methods for target detection and tracking will be
described. Further, an optimized navigation scheme will be developed according
to an information-seeking approach. Some examples of simulation results and
future directions of work will be finally presented highlighting the advantages
of dynamic and reconfigurable networks over static ones.
