There are various types of UAV countermeasure equipment, each with its unique working principle and applicable scenarios, and they also have different advantages and disadvantages. The following is a detailed comparison:
|
Type of Countermeasure Equipment
|
Advantages
|
Disadvantages
|
|
Portable Electromagnetic Jamming Gun
|
Compact and lightweight, easy for individual soldiers to carry and operate; can respond quickly to sudden situations, and can swiftly handle illegal photography and close-range UAV threats
|
Short operating range, generally within a few hundred meters; limited jamming range, difficult to deal with long-distance targets
|
|
Vehicle-Mounted Electromagnetic Jamming System
|
High mobility, can be quickly deployed to different locations; long operating range, up to several kilometers, equipped with multiple antennas, covering a wide airspace
|
Relatively large in size, requires vehicle mounting, less flexible compared to portable devices, and has a relatively high cost
|
|
Fixed Electromagnetic Jamming Base Station
|
High power, wide jamming range, can monitor the airspace of specific areas 24 hours a day; can be integrated with other security systems to achieve automated defense
|
Fixed installation location, lack of mobility, suitable for specific important places, high upfront construction and maintenance costs
|
|
Laser Strike Type
|
Fast speed, high precision, strong anti-jamming ability, can effectively strike target UAVs instantly
|
The laser is easily affected by scattering and absorption during atmospheric propagation, resulting in reduced strike effectiveness due to energy attenuation; requires high power, needs a large power supply system, currently mostly in the experimental research and development stage, with high costs
|
|
UAV Capture Net Type
|
A gentle countermeasure method, does not cause serious damage to UAVs, convenient for subsequent investigation; suitable for densely populated areas or areas with important facilities
|
Limited operating range, high precision and timing requirements for launching the capture net, difficult to operate, and there is a risk of capture failure
|
|
Acoustic Jamming Type
|
Environmentally friendly, does not produce electromagnetic radiation pollution, suitable for places with high requirements for the electromagnetic environment
|
Short operating range, easily affected by environmental noise, unstable jamming effect, currently the technology is not yet mature, still in the research and improvement stage, not widely used
|
|
Navigation Deception Type
|
A "soft kill" method, does not cause physical damage to UAVs, has a good countermeasure effect on consumer-grade civilian UAVs that rely on satellite navigation
|
Complex technical implementation, requires precise simulation of satellite signals; easily affected by UAV anti-jamming measures, with the possibility of countermeasure failure
