Drones and UAVs flying in the proximity of an airport or airfield is a current concern. Drone and UAV operators or pilots should not fly near the airports or airfields because the flying aircraft have difficulty in seeing them. In addition, some drones and UAVs fly into these critical areas for hostile objective including create safety hazards to the airport and airfield environments. This paper discusses the modern radar design techniques used in anti-drone solutions and counter unmanned aerial vehicles system (CUAS) to detect and tracking them so that counter measures can be executed to prevent damages, in terms of lives lost or financial suffers. The paper development will commence with problems and technology progression in terms of drones and UAV advancement, the design features desired are then discussed and last but not least, a design case will be evaluated to conclude the present anti-drone and UAV radar design.
