Radar sensor UAV altitude / auxiliary landing perimeter security monitoring

      2022-06-14 1012

      Radar sensors are used for perimeter security monitoring of drones' altitude setting/assistance landing. In order to complete diversified operations such as patrol inspection, security, commercial flight, agricultural insurance and fertilization, radar sensors can be installed in different locations to help various drones to achieve settings. Fixed height and obstacle avoidance functions. The radar sensor is a low-power, high-frequency, small-volume ranging radar module. It is installed under the drone, and can detect the distance information from the lightning strike to the ground in real time and feed it back to the drone, so that the drone can be In the process of descending or hovering, the descending speed or flight height can be adjusted in time. Widely used in logistics drones, surveying and mapping drones, formation performance drones, etc.

      Radar sensor UAV altitude / auxiliary landing perimeter security monitoring

      Ardupilot and PX4 supporting flight control hardware:

      1. Pixhawk1

      2. Pixhawk Cube Series

      3. Pixhawk Flight Controllers from Holybro

      4. CUAV Series

      5. Beagle Bone Blue

      6. Drotek Pixhawk3


      Program advantages:

      1. The radar sensor is small in size, highly flexible in installation, and small in blind area.

      2. Detection frequency, data stability, high precision, to solve the problems of missing GPS signal and poor low-altitude accuracy. Signal strength information assists the flight control to filter the data; the beam angle is small, and the pointing accuracy in complex environments is better than millimeter waves.

      3. Radar sensors are cost-effective.

      4. Support flight control system, such as Pixhawk, plug and play.

      5. US FAA certification (TF03) support


      At present, some screens or obstacles are set up around traditional buildings, and personnel are arranged to strengthen patrols, which cannot meet the current security needs of perimeter security. Therefore, based on the length single-point radar sensor of the perimeter security plan, a high-performance single-point length radar sensor is used. Build invisible electronic fences with cameras or alarms. The program can monitor intruders in real time and alert them, triggering relevant security efforts. Radar sensors serve application environments such as factories, banks, and prisons, and are not easily affected by outdoor environments.


      Everyone's safety awareness is gradually improving. In order to solve the problem of asset loss and staff safety caused by personal behaviors such as intrusion, theft, and destruction, the perimeter security requirements of various manufacturing industries are gradually increasing. Perimeter security precautions can be divided into two categories: tangible and intangible. Because physical electronic fences are not immediately alarmable and are very easily destroyed, they are now slowly being replaced by invisible perimeter security precautions. Launched a perimeter security protection plan based on long-distance single-point radar sensors, using high-performance single-point radar sensors to cooperate with cameras or sirens to build invisible electronic fences. The scheme can monitor intruders in all directions at all times and carry out alarms, triggering relevant security work.


      1. Radar sensor composed of perimeter security system

      1. Intrusion long-distance monitoring

      All-weather uninterrupted radar at any point for real-time monitoring throughout the whole process

      2. Locating Intrusion

      According to the ranging information of the radar sensor, the system can locate the occurrence point of the intrusion behavior in real time when judging the occurrence of the threat intrusion behavior, so that the security personnel can take effective measures to the target in time to prevent the occurrence of subsequent intrusion behaviors.

      3. Can work with other monitoring systems (sound, photoelectric alarm).


      2. Customer benefits

      Radar sensors have obvious technical advantages over traditional electrical sensors in sensor network sensors:

      1. It has good reliability and stability, small size and light weight;

      2. Measuring distance up to 50m;

      3. The measurement speed is fast, the feedback is timely, and the response time is the fastest 1ms;

      4. The distance error is within 10cm, accurate and reliable;

      5. Low energy dependence, which can greatly save the cost of power supply equipment and lines;

      6. It is resistant to electromagnetic interference and corrosion, and can work in harsh chemical environments, field environments, etc.;

      7. No radiation, no flammable and explosive materials, waterproof, environmental protection, etc.;


      3. Application scenarios

      Arrange multiple radar sensors around the area to be detected to form a closed shape, and connect the background data transmission equipment to realize perimeter detection. It is used in important places such as airports, high-end villas, private islands, fish farms, power plants, nuclear power plants, prisons and so on.
