Counter-drone technology comprises of a system that is capable of detecting and intercepting drone. A large number of incidents pertaining to use of drones for illegal and criminal purposes have come to light. Drones are available commercially-off-the-shelf (COTS) and criminals are using it to deliver weapons and contrabands. The sophisticated drones are equipped with latest stealth and evade technologies that have further raised new concerns for the security forces and Law Enforcing Agencies (LEAs). In order to check drone related security and unlawful activities, there is a need to place suitable Counter-drone technology. This article reviews the existing Counter-drone underlying technologies, associated legal and regulatory issues, and proposes a conceptual model of Counter-drone system that takes into account the improvements required in the existing design.
