As the usage of drones increases, so does the need for protection against unwanted aerial intrusion or careless operators. Because of the danger posed by the misuse of uav's, new technology is required that mitigates potential drone threats. Drones (uav's) have been around for many years, the wide acceptance, low prices and implementation is beginning to cause new conflicts. What is required is heightened awareness of the potential threat that this technology can pose to physical security and critical infrastructure.
To combat intrusion and threat, couple of detection technologies are explored, like Thermal Cameras, Radio sensors: - OR Radio sniffers, Compact Surveillance Radar (CSR). While these acoustics, radar and radio are also able to detect and potentially classify the detection as a drone, but they have multiple limitations.
