Description
Technical field
The present invention relates to one kind to be mainly used for Space TT&C field, can be applied in Situation Awareness field complete
Airspace multi-beam collaboratively searching method.
Background technique
For increasingly developed more stars while observing and controlling demand, The present invention gives one kind to survey simultaneously for full airspace multi-beam
The array antenna target search technology of control.The reception of digital multiple beam antenna refers to TTC & DT Systems foundation beam position information,
Selection activation array element simultaneously controls its multiple weight progress Wave beam forming, completes to receive in the signal of predetermined direction, and has neither part nor lot in wave beam
The region of formation, then closing passage.Multiple beam signals form under the control of not coactivation array element and multiple weight and generate direction
The composite signal of different directions.If wave beam will appear effective hole with the reduction of scanning angle using planar array antenna
Diameter reduces, and causes Wave beam forming signal in degradation problem at low elevation angles, shows as beam broadening, gain decline, can not
Realize full airspace covering.At the same time, the TTC & DT Systems based on nonnumeric multibeam antenna need multiple base stations real
Now effective covering in full airspace, and multistation equipment and capital construction cost are higher, need more people on duty, should not realize automation.To adapt to
The regulatory requirement of full airspace navigation constellation, full airspace TT&C system must use the conformal antenna for covering full airspace, while generate more
A wave beam carries out effectively search and judgement to satellite within the scope of the full airspace of detection realization by carrying out to downlink signal.
For the comprehensive control business demand for guaranteeing extensive in-orbit spacecraft, Incorporate TT & C architecture necessarily future
The development trend of aerospace system comprehensive control net.In terms of ground observing and controlling net, it is based on conformal array antenna sum number word multi-beam shape
Have at the single step form ground observing and controlling system of technology while the observing and controlling of full airspace multiple target spacecraft and fortune pipe ability, is in the future
The mainstream development direction that face tracking and command network is established.Being switched fast for antenna beam direction may be implemented in full airspace Multi target TT&C antenna
With tenacious tracking, the control instruction passed down in conjunction with measurement and control center realizes the Multi target TT&C business singly stood.

According to the target information received, TTC & DT Systems are controlled to the mesh for newly entering target and tracking, and obtaining according to tracking target
Mark information, target information parameter of the real-time update target in dynamic object library module.
The target information parameter includes the azimuth for finding target, pitch angle and corresponding power, the band for receiving signal
The target informations such as width.
The search phase is initialized in full airspace, target search module is according to the track of TTC & DT Systems monitor area target
Highly, wave beam residence time needed for maximum flying speed, beam angle and target search module complete target detection calculates
Corresponding pitching angular coverage is scanned in wave beam number needed for full airspace scanning, single orientation omnidirectional under the conditions of not missing inspection,
Twice in succession the scanning of orientation omnidirectional pitching to overlapped scan area, and according to the state modulator multi-beam that is calculated
Collaboration is scanned, to realize the initialization search covered from high pitch angle to the full airspace of low pitch angle.
In low pitch angle monitoring phase, minimum monitoring pitch angle that target search module is provided according to TTC & DT Systems,
Wave beam residence time needed for target search module completes target detection, orientation division number, and combining target orbit altitude,
Maximum flying speed and beam angle information calculate and participate in searching for minimum wave beam number under the conditions of not drain sweep, and according to calculating
The state modulator multi-beam arrived, it is comprehensive to progress subregion collaboratively searching scanning, realization pair to low pitch angle ring-type monitor area
Monitoring of the low pitch angle 360 degrees omnidirection to airspace range, meanwhile, TTC & DT Systems with fresh target judgment module, wave beam with
The nothing that track module and dynamic object library module auxiliary complete full airspace is searched for generally and is monitored.
Refering to Fig. 2.With orbit altitude between 200 kilometers -2000 kilometers, low rail of the cycle of operation not less than 90 minutes is defended
Star, it is 3 degree, wave beam residence time t that system phased array, which provides beam angle α,0To be described in detail for 50ms.Since rail flies
Row device with low-orbit aircraft operation angular speed it is most fast, around the earth operation one circle the time required between 90 minutes with 120 minutes it
Between.Therefore, target is necessarily smaller than relative to earth centre of sphere operation angular speed equal to 0.067 °/s (4 °/min).Since the earth is average
Radius is about 6371 kilometers, this is far longer than minimum orbit altitude, therefore target is run for TTC & DT Systems

Wherein, h indicates orbit altitude, and r indicates earth radius.
Refering to Fig. 3.Full airspace initialize the search phase, target search module take from high pitch angle to low pitch angle according to
The secondary mode for carrying out the scanning of 360 ° of orientation omnidirectionals carries out full airspace initialization search, comprehensive to when scanning at the m+1 times, refers to
Fixed this time scanning is comprehensive to scanning with the m times, pitching to the overlapping equal with target maximum pitch angle variable quantity
Region, to avoid in adjacent twice sweep time interval due to movement lead to drain sweep target the case where appearance.
Refering to Fig. 4.It is comprehensive to during scanning search in single, target search module using unicast position effective coverage as
The starting point of multi-beam collaboratively searching, by K wave beam along pitching to linear array arrange, single row scanning effective coverage wave position 1,
Wave position 2, wave position 3 ... wave position N carry out 360 degree orientations and scan, according to 360 degree of orientations and pitching to the rectangular coordinate system of foundation
Spacing and adjacent wave of the pitching to adjacent beams central point is calculated with the geometrical relationship of the beam permutation matrix in wave position direction
