Channel correcting, the transmitting channel correction that can also be used for array antenna.In military aspect, it can be used as broadband radar system array day
The passage calibrator of line.At civilian aspect, passage calibrator of base station array antenna of wide spatial domain communication etc. can be used as.
The present invention is described in detail below in conjunction with accompanying drawing.
Embodiment 1
Fig. 1 is a kind of structural representation of the single ridge wideband waveguide coupling calibrator of eight coupling apertures 4 in the embodiment of the present invention
Figure.
As shown in figure 1, single ridge wideband waveguide coupling calibrator mainly includes：Rectangular waveguide 1, square ridge 2, impedance matching
Section 3, coupling aperture 4 and coaxial connector 5.
Coaxial connector 5 has two, is separately positioned on the two ends of rectangular waveguide 1, input or output for signal.
Single ridge wideband waveguide coupling calibrator profile is a rectangular parallelepiped structure, in the relatively square ridge 2 of rectangular waveguide 1
Eight coupling apertures 4 are provided with broadside, square ridge 2 is connected with coaxial connector 5 by impedance matching section 3, and signal is by therein
One coaxial connector 5 (another connects 50 ohm loads) input is exported, and completes the channel correcting of array antenna.
As shown in Fig. 2 the equidistant side broadside bottom for being opened in rectangular waveguide 1 of eight coupling apertures 4, due to the school of the present invention
Coupling aperture 4 is non-directional, the input/output terminal reciprocity of signal in quasi- device.
Square ridge 2 is arranged on the inside of rectangular waveguide 1, on rectangular waveguide 1 broadside relative with coupling aperture 4, and
Both center lines are overlapped.Impedance matching section 3 is connected between square ridge 2 and coaxial connector 5, for impedance conversion, with reality
The characteristic impedance that existing coaxial connector 5 is exported is 50 ohm of standard, left and right each one.
As shown in figure 4, square ridge 2 is the cuboid that a lateral section is rectangle, at the same with impedance matching section 3, coaxial connect
Connect device 5 and constitute the feed structure that single ridge wideband waveguide couples calibrator together, by adjusting the physical dimension of square ridge 2, together
When correspondingly change the length of transition matching section 3, thus it is possible to vary single ridge wideband waveguide couples the characteristic impedance of calibrator, makes it
Characteristic impedance changes to 50 ohms of standard, that is, realizes impedance matching, so as to be also 50 ohm coaxial with characteristic impedance
Connector 5 is smoothly connected.Array antenna for launching or receiving is connected by coupling aperture 4, and coupling aperture 4 is coupled out array day
The amplitude-phase value of signal in beta radiation unit, couples calibrator by single ridge wideband waveguide and is transferred to the signal being followed by generation
Device or signal correction receiver, complete the processing and antenna channels correction of signal.Because coupling aperture 4 is in the calibrator of the present invention
Non-directional, the input/output terminal reciprocity of signal.
Further, rectangular waveguide 1 using square ridge 2, coaxial connector 5 and between the two impedance matching section 3 one
The inside electric resonance structure that the single ridge wideband waveguide of composition couples calibrator is played, similar single ridged waveguides form is formed, so that single
Ridge wideband waveguide coupling calibrator has broadband character.Size can be obviously reduced in the cavity electric size of rectangular waveguide 1, weight
Amount effectively reduction, while having reliability high and compact conformation advantage.
When carrying out array antenna received channel correcting, by (another connects 50 ohm and born with one of coaxial connector 5
Carrying) connected signal generator is to single ridge wideband waveguide coupling calibrator injection correction signal, and coupling aperture 4 is correction signal coupling
Close in coupled radiating element, subsequent signal enters the receiving channel being connected with radiating element, finally enters respective
Receiver processing, so that the array antenna channel correcting under completing reception state.
When carrying out array antenna transmitting channel correction, signal is entered the radiating element of array antenna by transmission channel,
Single ridge wideband waveguide is coupled into by coupling aperture 4 again to couple in calibrator, it is then coaxially connected by one of those
Device 5 (another connects 50 ohm loads) is transferred to the processing of signal correction receiver, completes the array antenna passage under emission state
Correction work.
Embodiment 2
In airborne and spaceborne environment, due to the limitation in space, there are strict requirements to dimension volume, using ridge waveguide
It is one of preferred scheme to couple calibrator to be used for array antenna channel correcting.Waveguide couples calibrator because the waveguide form of use can
To be divided into rectangular waveguide coupling calibrator and ridge waveguide-coupled calibrator, wherein ridge waveguide-coupled calibrator is again with single ridged waveguides coupling
Close calibrator and double ridged waveguide coupling calibrator is common.Latter two form is all to couple calibrator in cavity by rectangular waveguide in fact
Inside loads the single ridge of feed or double ridges are developed, and advantage is to couple calibrator to double ridged waveguide coupling calibrator from rectangular waveguide
Bandwidth be gradually incremental, cavity size and volume are successively decreased step by step, have the disadvantage that complexity gradually strengthens.Therefore we want reality
When now carrying out signal calibration for frequency band very wide Wide band array antenna passage, ridge waveguide-coupled calibrator is a universal choosing
Select.It can bring broadband up to ultra wide band, and size and volume are obviously reduced, increased although implementing complexity, phase
It is also worth for the benefit that it brings.
In a word, for the calibration of amplitude and phase in terms of current array antenna passage, rectangular waveguide coupling calibrator, single ridged waveguides
Couple calibrator and double ridged waveguide coupling calibrator application it is all relatively common, but just realize bandwidth and reduce volume size side
Face, ridge waveguide-coupled calibrator has more obvious advantage, and this is to realizing that wide band array antenna channel signal is calibrated, undoubtedly
It is only selection.Because the size of the array antenna with constituting calibration system is limited, through choosing comprehensively, the present invention successfully have developed one
Plant the single ridged waveguides coupling calibrator for including eight coupling apertures 4.But at this it should be noted that in actual application,
The number of coupling aperture can select extension as needed, but not influence the realization of calibrator function.
For example often through the quantity of equidistant increase coupling aperture 4, single ridge including varying number coupling aperture 4 can be built
Wideband waveguide couples calibrator, can bring and be applied even more extensively and good economic benefit.
As shown in figure 5, just increasing to 52 the quantity of coupling aperture 4 is equidistant in the present embodiment, constituting has five
Single ridge wideband waveguide coupling calibrator of 12 coupling apertures 4.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
Any modifications, equivalent substitutions and improvements made within refreshing and principle etc., should be included in the scope of the protection.
