A method and system for countering drones

Abstract

The invention relates to a method for anti-UAV, which includes preset safe areas, and arranges antennas according to the range of the area; simulates the scene, forms the anti-navigation signal received by the UAV by generating the simulated position information of the safe area; When driving to the edge of the safe area, the real satellite signal received by the UAV is replaced by the anti-navigation signal, so that the UAV is located outside the safe area. It also provides anti-UAV system, including simulation control computer and anti-navigation signal simulation subsystem, timing subsystem, antenna feedback subsystem, simulation control computer sends operation instructions to anti-navigation signal simulation subsystem, anti-navigation signal simulation subsystem Based on the clock reference provided by the timing subsystem, the anti-navigation signal of the safe area is simulated, and the anti-navigation signal is transmitted to the UAV through the antenna feeder subsystem. The invention simulates satellite signals based on a high-precision time synchronization system, is suitable for static / dynamic areas, and quickly builds an accurate anti-UAV system.

Description

technical field [0001] The present invention relates to the technology in the field of anti-drone, in particular to a method and system for anti-drone. Background technique [0002] As the UAV open source project continues to mature, the manufacturing cost and use cost of UAVs continue to decrease; a large number of UAV R&D, manufacturing, and application companies have also boosted the popularity of civilian UAVs, but at the same time People have brought a series of troubles. UAVs can be used to peep at will, steal private information in the area, or have major hidden dangers such as putting dangerous items. [0003] At present, domestic anti-UAVs mainly focus on capturing and destroying UAVs. The means of realization mainly include the use of microwave weapons to shoot down and destroy UAVs and low-altitude interception. For example, low-altitude interception uses fixed or mobile launchers. When the "cannonball" flies near the target UAV, it casts a large net to entangle ...

AI Technical Summary

Problems solved by technology

However, the cost of these two systems is very high, the application range is narrow, and the hit rate is not high. Therefore, it is an urgent problem to be solved to suppress the "black flight" and countermeasures of UAVs economically and safely.
