Actually multiple (at least three) hydrophones are combined the basic matrix to be formed to be packed into a component, the acoustics transponder with setting
Together for measuring the relative bearing and distance of submarine target, and according to the received location information of GPS device and electricity sieve on ship
The course data of warp is calculated the geodetic coordinates of underwater hiding-machine (or towed body) by software in real time.This system can be widely used for various
The geodetic location of underwater equipment measures, can provide in real time measured target relative position and absolute geodetic coordinates, and show, export
With storage location data data.
Acoustic measurement apparatus includes acoustics transponder, transmitting transducer, receives acoustic array and electronic signal process part
Composition.It wherein receives acoustic array and generallys use long leg hydrophone array composition, is i.e. receiving hydrophone passes through connecting rod and electronic compartment portion
Point connection, far from electronic compartment bottom plate, hydrophone can it is contour also can high-low staggered-floor arrangement.
It is traditional when the acoustics of certain underwater hiding-machine is stealthy more demanding, i.e., all charging appliances need to be conformal with latent device
Long leg battle array can not be used since its structure is uneven on such latent device.The locating and tracking of latent device will be unable to realize.
Summary of the invention
The purpose of the present invention is to provide a kind of small sizes to receive acoustic array, to reach ultra-short baseline equipment positioning function,
The function of carrying acoustic array is not influenced simultaneously, meets the stealthy requirement of latent device.
In order to solve the above technical problems, the present invention provides a kind of small size reception acoustic array, comprising:
Mounting base, female battle array vibration member is arranged on the mounting base, and mother's battle array vibration member forms female on the mounting base
Battle array acoustic array；Wherein, the mounting base is equipped with multiple reserved locations；
Submatrix hydrophone is embedded in the reserved location.
Optionally, suspension installation and decoupling slot are equipped in the submatrix hydrophone
Optionally, the minimum number of the reserved location is 3.
Optionally, the quantity of the reserved location is no more than the 20% of female first quantity of battle array vibration.
Optionally, the reserved location circumferentially rotational symmetry.
Optionally, the mounting base is circle.
A kind of small size reception acoustic array, including mounting base are provided in the present invention, are arranged on the mounting base
There is female battle array vibration member, mother's battle array vibration member forms female battle array acoustic array on the mounting base；Wherein, the mounting base is equipped with
Multiple reserved locations；Submatrix hydrophone is embedded in each reserved location.By the reserved location in female battle array acoustic array and inlay
Embedding submatrix hydrophone, realizing female, son, battle array, technical process are simple altogether；The ultra-short baseline reception sound for being not take up exceptional space can be achieved
Basic matrix installation；The stealthy requirement for meeting latent device realizes ultra-short baseline positioning device on stealthy more demanding latent device
Using；Under the premise of not influencing primary sound basic matrix electroacoustic performance, the appropriate submatrix hydrophone for increasing ultra-short baseline positioning device is superfluous
The service life of ultra-short baseline positioning device can be improved in remainder amount.

Specific embodiment
It is further detailed to a kind of small size reception acoustic array work proposed by the present invention below in conjunction with the drawings and specific embodiments
It describes in detail bright.According to following explanation and claims, advantages and features of the invention will be become apparent from.It should be noted that attached drawing is equal
Using very simplified form and using non-accurate ratio, only to facilitate, lucidly aid in illustrating the embodiment of the present invention
Purpose.
Embodiment one
The present invention provides a kind of small sizes to receive acoustic array.Referring to Fig. 1, it includes installation bottom that the small size, which receives acoustic array,
Plate 1, the mounting base 1 are circle, female battle array vibration member 2 are arranged on the mounting base 1, mother's battle array vibration member 2 is in the peace
It fills and forms female battle array acoustic array on bottom plate 1.Wherein, the mounting base 1 is equipped with multiple reserved locations 3, top view such as Fig. 2 institute
Show.It is embedded with submatrix hydrophone 4 in each reserved location 3, such as Fig. 3.Wherein, as shown in figure 4, in the submatrix hydrophone 4
Equipped with suspension installation 41 and decoupling slot 42, reinforce decoupling and vibration isolation, and mutual between submatrix and female battle array to reduce by this method
Interference.Further, the minimum number of the reserved location is 3, and is no more than the 20% of female first quantity of battle array vibration；It is preferred that
, the reserved location circumferentially rotational symmetry.
In actual use, for female battle array acoustic array in order to guarantee certain operating distance, acoustic array aperture is larger, female a burst of
The quantity of member is usually more than 1000 or more, in the present embodiment one, chooses 8 female battle arrays on some diameter circumference in its plane
Reserved location of the position of array element as submatrix hydrophone, as shown in Fig. 2, relative populations are only less than 1%, and circle rotation pair
Position is claimed to lay, to original female battle array acoustic array electroacoustic performance, such as directive property, impedance, sound source level Index Influence can be ignored not
Meter, sound source level, which reduces, is no more than 0.1dB, is much smaller than underwater acoustic measurement error, and then will not influence original operating distance and precision.
By effectively designing, satisfactory submatrix hydrophone is realized in the volume of reserved location, is installed and is decoupled by suspension
The effective measures such as slot, are directly installed on reserved location.Preferably, the radiating surface of submatrix hydrophone need to be with former female battle array acoustic array
Radiating surface same shape, to realize that primary and secondary battle array is conformal.
Appropriate on female battle array acoustic array several positions mostly can be reserved, when the quantity of reserved location is no more than the mother
On battle array acoustic array female battle array shake the 20% of first quantity when, the influence to female battle array acoustic array is no more than 0.2dB.But for ultra-short baseline
For positioning device receiving hydrophone device, it is 3 that reserved location, which at least uses number,.20 submatrix hydrophones are such as used, it can be into
Combination of the row more than 1000 kinds or more can theoretically realize that ultra-short baseline receives the work of acoustic array life-cycle.
The present invention designs the external form of ultra-short baseline positioning device submatrix hydrophone using the vacant space on female battle array acoustic array,
And it is embedded into reserved location, reach ultra-short baseline equipment positioning function, while not influencing the function of female battle array acoustic array, meets latent
The stealthy requirement of device.Ensure that submatrix hydrophone reaches certain receiving sensitivity requirement in fixed space by trial-production, while again
It is able to satisfy great direction.This method is simple, reliable and effect is obvious.
Foregoing description is only the description to present pre-ferred embodiments, not to any restriction of the scope of the invention, this hair
Any change, the modification that the those of ordinary skill in bright field does according to the disclosure above content, belong to the protection of claims
Range.
