Construction of Anti-UAV Radio Active Defense System
1. Project requirements
The development and illegal abuse of drone technology have brought security risks and threats to important targets such as airports, prisons, troops, and nuclear power plants, such as the abuse of small drones, illegal intrusions, and terrorist attacks. UAVs belong to the category of "low, small and slow" targets. They generally have the characteristics of low-altitude and ultra-low-altitude flight, low flight speed, and are not easy to be detected, which brings great challenges to target detection. The need for prevention and control is urgent, and it is of great significance to build a UAV defense system that includes radio detection, radar detection, UAV interception systems, and UAV management and control platforms.
2. System overview
The UAV defense system drone jammer consists of a radio detection system, a radar detection system, and an interception system. Create an early warning circle with a radius of 3 kilometers and a disposal circle with a radius of 1.5 kilometers.
Through the rapid detection and identification of drones and drone remote controllers in flight status, the connection between the drone and the remote controller is cut off from a long distance, and the drone can be controlled for forced landing or return to flight. , to ensure the safety of low-altitude airspace or restricted airspace.
3. Introduction of front-end products
The function parameters of the drone inspection and punching machine:
1. Passive detection: It only receives and does not transmit any electromagnetic signals, and does not interfere with other communications.
2. Realize unattended: Open the UAV defense strategy, can formulate defense strategies such as monthly plan, weekly plan, daily plan for detection and interception, with unattended, fully automatic detection and interception.
3. Advance warning: In the designated control area, the remote control of the drone can be detected and identified in advance when it is turned on, and manual or automatic interception can be taken in advance before the drone takes off, so that the drone cannot take off.
4. Self-contained data storage function;
5. Model identification: It can identify the same model and the same type of UAV, identify the UAV model and unique electronic fingerprint
6. Multiple detection function: In the designated control area, multiple drones can be detected at the same time.
