Description
Technical field
The present invention relates to waveguide slotted array field of antenna, and in particular to waveguide Cylindrical Conformal slot array antenna radiates row between battle array
Wave phase control method.
Technical background
Crack array antenna is usually planar array, including coupling battle array and radiation battle array, and energy is coupled to spoke by coupling array
Battle array is penetrated, is radiate energy by radiating slot, coupling battle array and radiation battle array are all made of resonant mode design, guarantee each radiating slot
Same Xiang Yaoqiu.More and more to require to need antenna and platform carrier conformal, this proposes higher want with regard to counterincision Slot array
It asks.Cylindrical Conformal slot array antenna requires antenna and Cylindrical Conformal, so that constituting more radiation linear arrays of radiating curtain along cylinder
Arrangement, every radiation linear array is no longer in the same plane.In the beam pattern in conformal face, due to conformal array antenna
Conformal face is curved surface, and each radiation line source thereon is not on the same plane in space, every radiation linear array to the flat mouth imagined
Space of planes distance is different, and spatial path difference causes nonlinear phase poor on flat mouth face, if do not compensated to phase difference,
Antenna pattern performance will reduce, and gently then minor lobe is deteriorated, and seriously then will lead to main lobe division.For example diameter is the cylinder of 30 λ
On, front path length difference maximum caused by equivalent flat mouth face of wide about 10 λ of arc is differed up to 260 °, by calculation shows that, if not mending
It repays, antenna main lobe can split head, it is therefore necessary to this is designed, its phase difference is compensated.
The design key of Cylindrical Conformal Waveguide slot array antenna is exactly the compensation for solving space quadrature between radiation linear array
Problem, existing solution is: mode presented using end to radiation linear array, i.e., is fed from one end of radiation linear array, by adjusting
The distance that initial radiation is sewn to feeding point in every radiation linear array can change the excitation phase of every radiation linear array, thus to sky
Between phase difference compensate.End feedback specific implementation can be the direct feed of waveguide power division network or coupling lap gating system feedback
Electricity, coupling gap feeding classification can couple energy and phase by adjusting the structure of each coupling slot to control, in document " circle
The conformal lap gating system of column " in be exactly using end present plus couple gap by the way of control radiation linear array current feed phase, realization space phase
Displacement error compensation.But haveed the shortcomings that using above-mentioned end feedback mode obvious: bandwidth is very narrow, and radiation linear array is longer, radiates linear array
The upper more bandwidth of radiating slot number are narrower, because the bandwidth of lap gating system is inversely proportional with the gap number in every linear array.For this purpose,
Single radiation linear array is generally divided into several submatrixs in the design of conventional radiation battle array, each submatrix is coupled from submatrix center and presented
Electricity, Subarray partition is more, and bandwidth is wider.But the Cylindrical Conformal lap gating system based on end feedback principle compensation space phase difference is obviously difficult
Bandwidth is expanded with the mode for dividing submatrix, which limits antenna performance promotions, are not suitable for engineer application.
Summary of the invention
The purpose of the present invention is in view of the above problems, providing one kind to improve antenna radiation pattern, it is more suitable for work
The current feed phase method of linear array is radiated in the control Cylindrical Conformal waveguide slotted array of Cheng Yingyong.
To achieve the above object, traveling-wave phase controls between the present invention provides a kind of Conformal Waveguide slot array antenna radiation battle array
Method has following technical characteristic: according to bandwidth needs are expanded, the radiation linear array in Cylindrical Conformal waveguide slotted array being divided into
Any number of radiation submatrixs, using coupling slot from the apex drive of each radiation a period of time battle array, in each radiation submatrix waveguide
The diaphragm with waveguide grade height thickness is added above the coupling slot of central area, controls each radiation submatrix both ends Waveguide slot traveling wave
Power.
Further, deviate the distance at radiation submatrix center and the width of diaphragm by adjusting diaphragm, realize power
Distribution and standing wave matching.
Further, two radiating slots adjacent with coupling slot in each radiation submatrix are adjusted to coupling slot distance d1
To control the traveling-wave phase at radiating slot, realization space quadrature compensation.If the difference that need to be compensated is ΔΦ, and guarantees each spoke

It is easy to Project Realization, is able to achieve high performance Cylindrical Conformal slotted waveguide antenna.The present invention splits Cylindrical Conformal waveguide
Radiation linear array in seam battle array is divided into any number of radiation submatrixs, above the central area coupling slot of each radiation submatrix waveguide
The diaphragm with waveguide grade height thickness is added, can effectively expand the beamwidth of antenna, compensate for since cylinder lap gating system ray path is long
The not equal caused phase difference of degree, realizes that the face Q is conformal, can flexibly control the row of radiating curtain in Cylindrical Conformal Waveguide slot battle array
Wave current feed phase can compensate space quadrature perfection, not only improve the radiance of array, and significantly improve cylinder
The directional diagram of Conformal Waveguide lap gating system, greatly improves antenna performance.
The present invention radiates at a distance from two radiating slots to coupling slot adjacent with coupling slot in submatrix using adjustment is each
d1To control the traveling-wave phase of excitation radiation seam, realization space quadrature compensation, using the traveling wave feedback of slot-coupled apex drive
