Detailed description of the invention
A kind of space space electricity-feeding many bases continuous wave phased-array radar that the present invention proposes, including: space-based is sent outPenetrate front, ground multistatic radar transmitting-receiving main website, multiple receiving station and data transmission and control system.
Solar energy on geo-stationary orbit is converted into microwave energy and is sent to ground and feeds by space launch front,After ground multistatic radar transmitting-receiving main website receives microwave and it is carried out amplitude and phase controlling, then it is transmitted into certainlyBy space, institute's early warning spatial domain is carried out all direction searching, is dispersed in receiving station everywhere and the linkage of transmitting-receiving main website,Receive and follow the tracks of the scattered signal of the searched target of transmitting-receiving main website, carry out conduct monitoring at all levels, abolish targetStealthy function.
As it is shown in figure 1, the space launch front in present embodiment, by 50 2 × 2m2Submatrix composition,Each submatrix is made up of the row feedback of 256 transversely arranged row feedbacks and a longitudinal arrangement.Row feedback includes oneIndividual row feedback 1/256 power division network, input and the outfan of row feedback 1/256 power division network are respectively connected with relayingAmplifier module.Every row feedback all includes that a row presents 1/256 power division network, row feedback 1/256 power division networkInput connects the relaying amplifier module of row feedback 1/256 power division network outfan, row feedback 1/256 power division networkOutfan connect and have power amplifier assembly, antenna radiation unit to be integrated in the outfan of power amplifier assembly.Space launch front can provide 256*256 antenna, and feed scope is wide.
Space launch front is arranged in space, and from too airborne acquisition solar energy, collection efficiency is high, not by skyThe impact of the natural environment such as gas.Meanwhile, this space launch front simple in construction, be prone to processing, low cost；Power division network insertion loss is low, and the defeated framing of each port is mutually discrete little, and antenna element mutual coupling is little, complicated at spaceStable physicochemical property is had under environment.This space launch front belongs to the light-duty front of miniaturization, narrow beam, lowSecondary lobe, beam position are precisely stable, and normal service life is more than 30 years.
Power amplifier assembly in present embodiment can use GaN millimeter wave monolithic integrated circuit.GaN is because of itBroad stopband is so electrical breakdown strength is high, and therefore its reliability is the highest；Meanwhile, its saturated electron drift velocityHurry up, therefore power density is big, efficiency is high, has the features such as chemical stability and capability of resistance to radiation are strong；Its heatConductance is big, and operating temperature is up to more than 700 DEG C.When being embodied as, power amplifier assembly may be used without GaAs.
Ground multistatic radar transmitting-receiving main website includes microwave lens and reflective front.
As in figure 2 it is shown, microwave lens includes reception antenna front, multiple phase shifter and launching antenna array face,Receiving antenna array face includes that multiple reception antenna, launching antenna array face include multiple transmitting antenna, reception antenna,Phase shifter and launch antenna one_to_one corresponding, each reception antenna connects corresponding sending out by the corresponding phase shifterPenetrate antenna.Reception antenna is launched by transmitting antenna after receiving solar energy shifted device phase shift.
As it is shown on figure 3, reflective front includes that antenna element, phase shifter and metal that multiple antenna forms are anti-Penetrating plate, antenna and phase shifter one_to_one corresponding, each antenna connects metallic reflection plate by the corresponding phase shifter.Antenna element receives the electromagnetic energy on geo-stationary orbit, is reflected by metallic reflection plate after electromagnetic energy shifted device effectAfter launch from antenna element again.
Ground multistatic radar transmitting-receiving main website is directly used for thunder the microwave energy from space by Secondary EmissionReach radiation source, it is not necessary to the microwave energy reconvert being delivered to ground is become direct current energy, eliminates current space tooRectification in sun energy utilizing works receives program, improves energy conversion efficiency, reduces use cost.
Multiple receiving stations being positioned at remote districts, manufacturing cost is relatively low, and function is the most single, is used for receiving groundThe signal that face multistatic radar transmitting-receiving main website launches, with the linkage of transmitting-receiving main website, receives and follows the tracks of searched meshTarget scattered signal, monitors in all directions to target, abolishes stealthy function.
Data transmission and control system, the data transmission between each command centre, and control work, exampleAs arranged key monitoring region or target etc..
As shown in Figure 4, using plasma phase shifter phase shifter in present embodiment, by waveguide and glassStorehouse forms, and glass storehouse is arranged on waveguide inside and is tightly connected with waveguide sidewalls, fills indifferent gas in glass storehouseBody.Noble gas has normality and plasma state two states, is formed for plasma state when noble gas activatesIonized space, ionized space is revealed as metal boundary to electromagnetic wave, by controlling noble gas two statesSwitching can change waveguide metal boundary dimensions, controls phase shifter work.The activation of noble gas can be by accessingLow-voltage realizes.When being embodied as, the phase shifter may be used without other digital phase shifters.
Plasma phase shifter insertion loss is little, and its application band can contain microwave and millimeter wave, and precision is high；PhaseMoving control device only needs simple low-voltage to realize, and control circuit power consumption is little.The plasma phase shifter tiesStructure is simple, and low cost, reliability are high, can be mass.
Present embodiment provides microwave signal by space feed, and microwave signal is by microwave lens and reflective arrayAfter formula antenna receives, after the amplitude of received signal and phase place are adjusted and control by each reception antennaBeing transmitted into free space again, the continuous wave phased array multistatic radar of Special composition feed system launches main website,Receive and follow the tracks of the scattered signal of searched target by launching main website with linking of receiving station, carry out full sidePosition monitoring, abolishes the stealthy function of target.
The radar that present embodiment provides lays the foundation for the following high-tech information war of reply, makes radar haveAnti-stealthy, Anti-antiradiation missile, anti-interference, find the ability of target in advance, for NMDIn base radar one preferred version is provided.
In embodiment of above, the solar energy collected radiates earthward with the form of microwave, when being embodied as,Millimeter wave can also be used.
The above, the only present invention preferably detailed description of the invention, but protection scope of the present invention not officeBeing limited to this, any those familiar with the art is in the technical scope that the invention discloses, according to thisThe technical scheme of invention and inventive concept thereof in addition equivalent or change, all should contain the protection in the present inventionWithin the scope of.
