Abstract

In recent years, the drone market has had a significant expansion, with applications in various fields (surveillance, rescue operations, intelligent logistics, environmental monitoring, precision agriculture, inspection and measuring in the construction industry). Given their increasing use, the issues related to safety, security and privacy must be taken into consideration. Accordingly, the development of new concepts for countermeasures systems, able to identify and neutralize a single (or multiples) malicious drone(s) (i.e., classified as a threat), has become of primary importance. For this purpose, the paper evaluates the concept of a multiplatform counter-UAS system (CUS), based mainly on a team of mini drones acting as a cooperative defensive system. In order to provide the basis for implementing such a system, we present a review of the available technologies for sensing, mitigation and command and control systems that generally comprise a CUS, focusing on their applicability and suitability in the case of mini drones.

Highlights

  • In recent years, the drone market has had a significant expansion, especially in the consumer sector

  • We refer to drones that communicate with the remote pilot through communication standards such as IEEE 802.11 (Wi-Fi), a case that covers a large part of commercial drones

  • The size, weight, required power and cost of the cameras is such that their use on drones does not find particular impediments and certainly makes it possible to use them as a sensing system for C-unmanned aerial systems (UAS) for all operations of detection, identification and tracking

Summary

Introduction

The drone market has had a significant expansion, especially in the consumer sector. Improper use in the vicinity of an airport can represent a serious threat to public safety and a source of discomfort, as evidenced by the hundreds of flights canceled at London Gatwick airport in a few months of 2018 [2] For this reason, the development of technologies for the detection, identification and mitigation of malicious drones has become of primary importance. Mini drones represent an effective solution for the implementation of a CUS, being the ideal platforms for the proximal sensing and tracking of moving targets (e.g., intruder drones) in high-mobility scenarios. In order to provide the basis for the future implementation activities of a cooperative drone-based CUS, this work presents a review of the available technologies for sensing, mitigation and C2 systems by means of mini drones. We provide the main definitions and the basic concepts about cooperative drone-based CUSs
