Under straight line multi-beam mode, for each primitive in every linear array in 5 and 6 " ten " word array intersection regions
Form M tap independent, 1 independent tap of several primitives of crossing center connects No. 1 transmitter, be used to form compared with
The launching beam of big angle of release, irradiates biggish waters.M tap is connected to M receiver, by the conditioning to signal, forms M
A independent narrow beam, so as to measure shoal of fish multiple directions scatter echo.
Under the integrated mode of split beam and straight line multi-beam, which is to be completed at the same time detection and assessment function
Can, four quadrant primitives are connected to transmitter all the way, form the phased simple beam transmitting of vertical normal orientation, and four quadrants pass through
4 tunnels receive to form four individual receptions, realize the reception of split beam；Meanwhile as needed, vertically and horizontally wave beam independently connects
It receives or receives simultaneously, M tap connects the road M receiver, forms M narrow beam after improving received signal, realizes water
The reception of M wave beam of gentle vertical direction.Optionally, M tap can also be connected with each other with M transmitter, be realized phased
Emit narrow beam, is formed with the launching beam of directive property.
The present invention provide a kind of multiphase control planar array transducer array and phased method, simultaneously using a planar array
Realize split beam, the transmitting and reception of straight line multi-beam various modes or integrated mode.
Planar phased array of the invention is divided into 4 quadrant areas, 2 line array regions of " ten " word battle array of 1 intersection,
Each quadrant is divided into transverse and longitudinal bidimensional, is made of on every dimension direction N number of primitive, wherein N is by beam angle, transfer efficiency and secondary lobe
Grade determines.
When split beam, all primitives of four quadrants emit simultaneously without phased, can form normal side in space
To simple beam occur, each primitive is connected respectively in 4 taps in 1~4 four quadrants, and individual reception can be in space shape
It is received at split beam.
Each line array in " ten " word intersection region arranges primitive according to required beam angle and numbers of beams
Quantity structures the formation between each primitive according to half-wavelength, meets spatial sampling theorem.When selecting line array length, simultaneous
Care for the size of four quadrant primitives of split beam.
Under straight line multi-beam mode, for each primitive in every linear array in 5 and 6 " ten " word array intersection regions
Form M tap independent, 1 independent tap of several primitives of crossing center connects No. 1 transmitter, be used to form compared with
The launching beam of big angle of release, irradiates biggish waters.M tap is connected to M receiver, by the conditioning to signal, forms M
A independent narrow beam, so as to measure shoal of fish multiple directions scatter echo.
It mixes under split beam and straight line multi-beam mode, which is to be completed at the same time detection and assessment function
Can, four quadrant primitives are connected to transmitter all the way, form the phased simple beam transmitting of vertical normal orientation, and four quadrants pass through
4 tunnels receive to form four individual receptions, realize the reception of split beam；Meanwhile as needed, vertically and horizontally wave beam independently connects
It receives or receives simultaneously, M tap connects the road M receiver, forms M narrow beam after improving received signal, realizes water
The reception of M wave beam of gentle vertical direction.
In addition, optional, M tap of every line array of " ten " intersection region can also be connected with M transmitter
Connect, form the narrow beam of phase control emission, realize directional transmissions, to realize the monitoring to the region of specific direction, certainly this
The monitoring range of sample is smaller.
Planar transducer array according to the present invention, by 4 split beam taps, 1 publicly tap, M are a vertical
Wave beam tap, M horizontal beam tap, 1 " ten " word battle array center emit tap, the entire total 2M+6 pumping of plane array transducer
Head, wherein M forms beam angle by line array and determines.
Example 1:
In conjunction with the schematic diagram of Fig. 1 planar array, the tap for defining 1st quadrant is Z1, and the tap of the 2nd quadrant is Z2, third quadrant
Tap be Z3, the tap of fourth quadrant is Z4, and the tap in the 5th area of horizontal linear battle array is X1, X2 ... XM-1, XM, such as Fig. 2 (a)
It is shown；The tap in the 6th area of vertical line battle array is Y1, Y2 ..., YM-1, YM, as shown in Fig. 2 (b).1 tap altogether, in 1
Centre transmitting tap；Total 2M+6 tap, wherein M forms beam angle by line array and determines.Assuming that line array forms beam angle
It is 5 °, the beam angle perpendicular to rectilinear direction is 50 °, then M=20, and the primitive number perpendicular to rectilinear direction is 2, connects 1 altogether
A tap, then the total tap number of planar array is then 46, the transmitting that 4 primitives that center transmitting primitive is 2 × 2 form is taken out
Head, launching beam width are 50 ° × 50 °.According between the half-wavelength of center between the corresponding primitive of " ten " cross linear battle array tap
Every structuring the formation, meet spatial sampling theorem.
Under split beam mode, need No. 1 transmitter 1, be connected with Z1~Z4, No. 4 receivers, be separately connected Z1~
Z4, transmitter 1 is for emitting single wave beam, and the transducer signal received by 1~4 four circuit receiver to four quadrants in water
It is handled after conditioning amplification, forms split beam.
Under multi-beam mode, No. 1 transmitter is needed to be connected to center transmitting tap, transmitter emits normal direction into water
Broad beam, irradiate a wider form waters.No. 20 receivers are connected to 20 taps of the horizontal linear battle array in 5 regions,
20 5 ° of narrow-band beam of horizontal direction can be formed, control jetting domain forms the dispersion image of the fan-shaped shoal of fish, realization pair
The monitoring of the shoal of fish and stock assessment.Similarly No. 20 receivers are connected to 20 taps of the vertical line battle array in 6 regions, can be formed
20 5 ° of narrow-band beam of vertical direction.If horizontal and vertical line array receives simultaneously, the shoal of fish of irradiation area is dissipated
It penetrates signal and realizes accurately measurement.Such as the schematic diagram that Fig. 3 is Wave beam forming.
Under mixed-beam mode, according to the actual needs broad beam transmitting of monitoring region or narrow beams transmission, it can be used
Center tap connects transmitter and emits broad beam, can also emit narrow wave using the transmitter that the launching beam of split beam connects
Beam is handled after the transducer signal conditioning amplification that four quadrants receive by the receiver of Z1~Z4 connection, is formed division
Wave beam.By the receiver of horizontal and vertical linear array 20 taps connection, after carrying out conditioning amplification to the signal for receiving energy converter
20 narrow-band beams are respectively formed, the acoustic picture in the monitoring waters of right-angled intersection is eventually formed.
Optionally, 20 taps of every line array of " ten " intersection region can also be connected with 20 transmitters, shape
At the narrow beam of phase control emission, directional transmissions are realized, thus realize the monitoring to the region of specific direction, certainly such prison
It is smaller to survey range.
It should be noted last that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting.Although ginseng
It is described the invention in detail according to embodiment, those skilled in the art should understand that, to technical side of the invention
Case is modified or replaced equivalently, and without departure from the spirit and scope of technical solution of the present invention, should all be covered in the present invention
Scope of the claims in.
