Due to potential risks of invaded drones, there is demands on UAS control and management.

The core of UAS management is to detect and identify drones.

Here below list general means of drone detection for reference.

not commonly used, due to short distance, and affected by surroundings too much.

Radar is through the emission of electromagnetic waves to irradiate the target and receive its echo , after the relevant technical means of processing , to extract certain information about the target object (such as the distance between the target and the radar, the rate of change of distance or radial speed , bearing , height and other information).

Advantages: all-weather, all-day detection , not blocked by fog , clouds and rain.

D isadvantages: easy to miss the phenomenon , and the surrounding environment has electromagnetic pollution , affecting the surrounding normal radio and GPS signals , expensive.

Optical detection is to collect UAV images through visible imaging , infrared imaging , thermal imaging and other technologies , and to locate , track and identify the UAV . It is a multi-band precision detection and imaging equipment with high mobility , high automation , and the ability to work stably for a long time .

Advantages: accurate detection at close range , with intuitive image data.

Disadvantages: vulnerable to obscuration , close distance , subject to the influence of the weather,

Radio spectrum detection is the use of radio frequency characteristics, according to the frequency to capture the signal, belongs to a passive electromagnetic monitoring method, has a strong target, usually for the UAV communication band are 433M, 900M, 2.4G, 5.8G, etc..

Advantages: can be automated operations, equipment is relatively small.

Disadvantages: easy to miss, false alarm, false alarm phenomenon and detection of the short distance, can not distinguish between enemy and UAV.

Cognitive radio protocol analysis technology is a technology to accurately detect and identify UAVs through reverse analysis of UAV communication protocols.

Advantages: the detection effect has a long distance and wide range , can pre-alarm , accurately distinguish the enemy from us , and can realize the unattended function , and has no effect on the surrounding electromagnetic environment.

Disadvantages: involves radio communication , reverse analysis , security engineering and other multidisciplinary intersection , technical difficulties.
