UAV detection (including once flying in the silence mode), by standard method of radiolocation.
With the development of modern technologies on creation and use of unmanned aerial vehicles (UAVs), protection of the airspace of various facilities against unauthorized entry of foreign drones is becoming more and more important. Visually unobtrusive quadcopters are small in weight and size, meanwhile they may carry photo and video equipment for covert shooting, explosive devices, flyers, etc. Various methods are used to detect UAVs, in particular active radar-location.
“AIR SHIELD DDR-4” radar ensures detection of UAVs penetrating the secured facilities, including those operating in radio silence mode, by an active radar. Such UAV detection system can be successfully used to protect industrial facilities, hydroelectric power stations, airports, stadiums and other places with a massive presence of people.
The principle of operation of “antidrone” type radar is based on reflection of ultra-high-frequency radio waves from the quadrocopter’s parts, emitted and received by the device’s circular antenna. Thus, a protected air hemisphere is created over the secured facility with a radius of action of up to 3000 meters and viewing angles of 90° horizontally and 90° vertically, continuously monitored by UAV monitoring system.
When a UAV appears in the secured airspace, radio signals are detected and identified. If any unauthorized interference is detected, an alarm is generated, drone’s current location, speed and direction of its flight are established. This information can be automatically transmitted to control channels suppression systems and data transmission of the UAV for its interception and neutralization.
New methods and materials are constantly being developed, in particular special coatings, changing UAV geometry, etc., to protect drones against detection by means of radar-location. Therefore, it is desirable to use integrated security systems using various methods of detecting and neutralizing UAVs to ensure effective protection of the facilities.
