2022-06-14
At present, UAV detection mainly adopts radar detection, which is combined with the mode of UAV anti-control equipment to realize protection. UAV is generally made of light wood and composite materials. This material has permeability, so it is not easy to be found. Only metal materials such as motors, engines, batteries and wires, coupled with its small size, greatly reduce the radar scattering area of the target itself and reduce the radar detection distance and detection probability, the ground reaction time is shortened.

At present, UAV detection mainly adopts radar detection, which is combined with the mode of UAV anti-control equipment to realize protection. UAV is generally made of light wood and composite materials. This material has permeability, so it is not easy to be found. Only metal materials such as motors, engines, batteries and wires, coupled with its small size, greatly reduce the radar scattering area of the target itself and reduce the radar detection distance and detection probability, the ground reaction time is shortened.
In terms of acoustic detection, the noise of the UAV target is mainly the engine noise and air disturbance noise generated during the flight, but a large part of the flight power of the UAV target is electric power, low noise, coupled with slow flight speed, making its noise level very low.
UAV detection radarIn terms of photoelectric detection, most of the artillery currently uses infrared fire control technology, and a considerable number of surface-to-air missiles and air-to-air missiles also use infrared detection and infrared guidance technology; laser rangefinders and laser target indicators have been widely used in short-range air defense weapons.
The motor or engine as the power of the UAV target, small size, high efficiency, low infrared radiation characteristics, so that in the anti-laser detection, the detection distance through infrared detection is greatly shortened, the UAV target is easier to use wave absorption, transmission and light guide and other materials, reduce laser reflection and stealth design, which increase the difficulty of photoelectric detection.
UAV detection radarManufacturers tell everyone that a single detection method cannot efficiently and accurately detect targets. A variety of cooperative detection methods will be the development trend of UAV target detection. Through the cooperation of various detection equipment, a detection system of "combination of one-point detection and multi-dimensional tracking" can be established, which can timely obtain various information such as target position, video image, radio frequency control, etc. and greatly improve the detection probability of UAV targets.
UAV detection radarManufacturers: What are the difficulties in the detection of drones?
Electromagnetic interference will reduce the detection ability of RF sensors. In urban environments, there are many potential sources of interference, including communication antennas, two-way radios, telemetry systems, and even wires and LED lights.
Some RF sensors, including some so-called "passive" sensing systems, may also emit RF signals that interfere with other communications, making them potentially hazardous in certain environments.
The camera system may confuse drones with birds or aircraft, may be affected by bad weather with low visibility, and may not be able to detect drones illuminated by strong light sources such as the sun.
Radar, some radio frequency sensors and EO/IR sensors, in order to detect targets, must maintain line-of-sight with the intruding drone, which is especially problematic in urban environments, because the drone may only appear in the sensor's line-of-sight for a few seconds and then disappear again.
