Description
Technical field
The present invention relates to field of aerospace technology, and in particular to a kind of multipath false target detection method, system and sky
Pipe automated system.
Background technique
Blank pipe and field prison automated system are that Civil Aviation ATM Sector is implemented to pass through core system that is empty and commanding over the ground
The monitoring data such as radar signal, ADS-B/ADS-C, MLAT, that is, SMR are handled, provide airflight situation and scene mesh for controller
Target is shown and various flight collisions and various abnormal alarms, by processing flight plan and dynamic telegram, mentions for controller
For flight plan and flight dynamical correlation information and management means, ensuring Civil Aviation ATM to the security implementation of empty commander's task
In play an important role.
Implementing to monitor that the processing of data source plays central role in commander to sky and over the ground using automated system, it is empty
The generation of decoy not only results in the abnormality alarmings such as unnecessary conflict and generates, and also results in controller's distraction, will answer
The time of the processing normal target is wasted in the processing of false target.
The false target that blank pipe secondary radar generates is broadly divided into following a few classes:
(a) multipath transmisstion (reflection)
The phenomenon that " multipath transmisstion ", i.e., there are one or more paths between transmitting radar antenna, target and receiving antenna.
Usual radar emission and reception use the same antenna, and the straight line path between antenna and target is known as directapath, and in radar
It is known as indirect path by the path that the reflection of the barriers such as ground or building reaches between antenna and target.It is different types of more
Path also generates Studies of Radar Detection performance different influences.In general, multipath transmisstion causes secondary radar decoy to generate
Main reason.
(b) asynchronous interference
Asynchronous interference refers to that secondary radar is received and is drawn within its effective coverage range by the inquiry of an other secondary radar
The answer of answering machine is played, this answer is asynchronous with the radar emission, so referred to as asynchronous interference.When aircraft be in radar A with
When the radar operating distance overlapping region B, radar A and radar B can be inquired to aircraft, and aircraft also can be to radar A and radar B
Carry out response.But radar B may will receive response of the aircraft to radar A sometimes, if radar B handles this response,
False target will be generated.
(c) around toroidal effect
When the transmitter of secondary radar is launched outward by antenna, there are two basic wave beams, i.e. inquiry wave beam and control
Wave beam.Inquire that wave beam has high-gain, narrow horizontal lobe and low sidelobe.Controlling wave beam has low gain, its gain is big
In gain of the inquiry wave beam in addition to main lobe on all directions.The effect of control wave beam is exactly for preventing aircraft from answering inquiry wave
The secondary lobe of beam is inquired, has the function that Sidelobe Suppression.
But under certain extreme cases, occur " secondary lobe breakdown ", the secondary lobe of control wave cover inquiry wave beam cannot be real
It is existing, the secondary lobe for being asked wave beam is triggered in the answering machine of the aircraft close to ground photo in this way, in antenna scanning process
In, the answering machine most of the time is within the power range of the secondary lobe of inquiry wave beam, and answering machine may continue or discontinuously answer
It answers, generates many decoys, occur " around toroidal effect ".
Air traffic control automation system usually requires to find from radar source when receiving the spurious signal of secondary radar appearance
Spurious signal suppressing method, and the false target processing scheme majority often used in automated system be to try to present it is original
Signal is not filtered or inhibits to original signal.Judgement or inhibition of the spurious signal in automated system generally require to lead to
It crosses artificial setting decoy shielding area or artificially decoy is confirmed to inhibit to false target.Department of Automation
The false target filtering generallyd use in system needs to meet following condition:
(1) the monitoring source of false target is detected in the monitoring source list of setting filtration zone；
(2) height of false target is detected in the altitude range of setting filtration zone；
(3) position of false target is detected within the scope of setting filtration zone；
If conditions above all meets, which can be false target by automated system, and be inhibited.
Although this kind monitoring data source false target filter method can accomplish the filtering of false target, filtered using this method
Some true targets can be frequently resulted in be filtered, or even when only the monitoring source can scan target, the filtering of target
It frequently can lead to the abnormal disappearance of aims of systems track；In addition use this kind of false target filter method for passive filter method,
After only having false target to be confirmed by control, false target can just be found and take the mode of setting false target shielding area
It is filtered, often " post ", still " remedying " effect may not be ideal.It is this that falseness is filtered using shielding area
It is not accomplish to find in advance due to failing to be designed on the characteristics of generating from false target that the drawbacks of target, which traces it to its cause,
It is prompted in advance.
