Counter UAS – C-SUAS
C-UAS Technology C-UAS can employ several methods to detect the presence of hostile or unauthorized UAS.
- The first is using electro-optical, infrared, or acoustic sensors to detect a target by its visual, heat, or sound signatures, respectively.
- A second method is to use radar systems. However, these methods are not always capable of detecting small UAS due to the limited signatures and size of such UAS.
- A third method is identifying the wireless signals used to control the UAS, commonly using radio frequency sensors.
These methods can be—and often are—combined to provide a more effective, layered detection capability. Once detected, the UAS may be engaged or disabled. Electronic warfare “jamming” can interfere with a UAS’s communications link to its operator. Jamming devices can be as light as 5 to 10 pounds and therefore man-portable (see Figure 1), or as heavy as several hundred pounds and in fixed locations or mounted on vehicles. UAS can also be neutralized or destroyed using guns, nets, directed energy, traditional air defense systems, or even trained animals such as eagles. DOD is developing and procuring several different C-UAS technologies to try to ensure a robust defensive capability.
