Background technology
In recent years, rapid as principal mode low-altitude low-velocity small targets Development of UAV using multi-rotor aerocraft, it takes the photograph in the air
As, it is high up in the air fly to, the ability such as figure is passed, transport is launched in real time, bring new challenge to work such as secrecy, security protection and anti-terrorisms.
With the rapid growth in unmanned plane market, risk of stealing secret information that unmanned plane " black fly " is brought, security protection risk, risk is feared cruelly
Also it is further prominent.Shooting, recording and some special equipment of the stealing secret information passenger that will constitute a serious infringement that unmanned plane provides carrying are hidden
The information security of the sensitive regions such as private and airport, military base.Unmanned plane invasion airport, important place etc., tracking and shooting occupy
The whereabouts of the people, seriously hinder individual privacy, it is also possible to cause trade secret to reveal；Unmanned plane invades military applications, can track
With the action of shooting military hardware, the core region such as military base and airport is surveyed and drawn etc., these can all cause military secret
Close leakage.Criminal also launches ability using the transport of unmanned plane, to dispensing prohibited items in prison or in densely populated place
Dangerous material are launched in place, and huge trouble has been manufactured to the safety of jails and anti-terrorism work.
Following defect be present in existing anti-unmanned air vehicle technique：1st, direct destruction is biased toward, directly destroys and easily causes nobody
Machine air crash and unexpected personal property injury；2nd, due to unmanned plane target very little, therefore radar can be found at a distance, but be difficult
Accurate tracking.Optical detection can be detected using visible ray to target, or be detected using the thermal infrared reflection of target,
This make it that optical detection is much more clear than radar；3rd, present anti-unmanned plane is mainly fixedly installed, and lacks mobility；4th, nobody
Machine detection and identification device type is single, can not detect most unmanned plane；5th, the conflicting mode used is relatively simple, can not
Disturb multiple different types of unmanned planes simultaneously；6th, do not linked between the existing each system of anti-unmanned plane, nothing can not be realized
Man-machine automatic defense.
The content of the invention
The goal of the invention of the present invention is：For above-mentioned problem, there is provided a kind of unmanned plane low-altitude defence system, adopt

Not and track；The optictracking device uses 37 times of continuous vari-focus high-definition television video cameras；The infrared tracking system
Using high-resolution infrared thermography.
Further, the photoelectric follow-up also includes active vibration and shock isolating apparatus, for keeping photoelectricity
Tracking system normal use on the move.
The interference counter system includes electromagnetism compact system, and the electromagnetism compact system includes orientation multi-jamming sources interference
Counter system.
The interference counter system launches the interference signal of certain angle, and other equipment will not be interfered；The hair
The angle penetrated is 0-15 degree, and transmission power is no more than 6 watts, and 300 watts of other equipment transmission power, can influence health, make
Adult body leucocyte straight line is reduced.
The course of work：Round-the-clock fan sweeping detection is carried out using radar, when finding flying object, carries out radar admission tracking point
Analysis, if being judged as doubtful unmanned plane, carry out vision algorithm analysis；If not unmanned plane, returns to radar detection；According to vision algorithm
After analysis, unmanned plane is locked after confirming as unmanned plane, obtains the azimuthal coordinates of unmanned plane；And interference counter system is called, carry out
Electromagnetism is suppressed, and compacting reset is carried out after suppressing successfully；If compacting is unsuccessful, locking unmanned plane is returned, re-starts electromagnetism compacting.
In summary, by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
1st, using electromagnetic interference, directly destruction is avoided to easily cause unmanned plane air crash and unexpected personal property injury.
2nd, photodetection and the combination of radar, the unmanned plane of detection can be tracked.Using air target identification
Vision algorithm processing, tracking effect are more preferable.
3rd, using fusion front end multisensor, different types of unmanned plane can be found in time, while fusion front end passes more
Sensor can obtain more comprehensive unmanned machine information, be advantageous to the interference in later stage.
4th, between each system can automatic linkage, cooperating, formed automatic defense.
