Remotely piloted vehicles have become more and more popular in recent years due to their increased availability on the market. In general, drones can represent a threat for public safety due to their potential misuse. This motivation gives rise to the need of devising specific methods and techniques to monitor sensitive areas, in order to deploy effective drone surveillance systems. These systems are designed to detect nearby undesired targets, and to neutralize impending threats. One of the main tasks involved in this scenarios is target localization, which can be performed with different approaches. In particular, in this article we carry out a study on the main literature works related to the framework of wireless target localization based on RF and WiFi techniques, providing a thorough analysis on the perspective of their deployment in drone surveillance applications.
