Embodiment 1

[0042] Embodiment 1 describes a lightweight torpedo acoustic guidance device.

[0043] Such as figure 1 and figure 2 As shown, the lightweight torpedo acoustic guidance device includes a seeker 1 and a transducer array.

[0044] Among them, the seeker 1 adopts a flat-top mine head structure, that is, the front end of the seeker 1 is a circular plane 2 with a relatively small diameter, and the rear end of the seeker 1 is the electronic cabin 3, and the electronic cabin 3 adopts a circular plane with a relatively small diameter. Larger cylindrical structures.

[0045] A transition section 4 is provided between the front end surface of the seeker 1 and the electronics compartment 3, wherein the transition section 4 adopts a streamlined arc section.

[0046] The transducer base array includes a front face planar array 5 and a side sparse circular array 6 .

[0047] Among them, the front-end plane array 5 includes a plurality of transducer array elements arranged on the front-...

Embodiment 2

[0065] Embodiment 2 describes a light-weight torpedo acoustic guidance device, except that the device has the following technical features that are different from the above-mentioned embodiment 1, and other technical features can refer to the above-mentioned embodiment 1.

[0066] Such as image 3 As shown, in order to avoid the impact of flow noise on the transducer base array as much as possible, this embodiment 2 changes the layout of the side sparse circular array 6, that is, each transducer array element 8 in the side sparse circular array 6 Arranged on the cylindrical section (that is, the electronic compartment 3 ) next to the streamlined arc transition section 4 .

[0067] In this case, the transducer array elements 8 are arranged at equal intervals in the circumferential direction, and the distance between the transducer array elements 8 in the circumferential direction is relatively large, and the direction of the transducer array elements 8 is the same as that of th...

Embodiment 3

[0069] Embodiment 3 describes a light-weight torpedo acoustic guidance method, which is based on the light-weight torpedo acoustic guidance device in the above-mentioned embodiment 1 or embodiment 2, so as to meet the guidance requirements of light-weight torpedoes in different mission stages.

[0070] Such as Figure 4 As shown, a light torpedo acoustic guidance method includes the following steps:

[0071] Step 1. The light torpedo enters the water stage, the light torpedo enters the water at a large angle, and the sparse circular array 6 on the side roughly senses the situation around the torpedo, and roughly determines the azimuth and distance of the target when the target is relatively close. The search results are consistent with those received before the torpedo launch The initial command of the target is through information fusion, and the integrated control system controls the torpedo to turn to the approximate spatial orientation of the target.

[0072] Step 2. In t...

Abstract

The invention belongs to the technical field of self-guided engineering of torpedo science, and discloses a light-duty torpedo acoustic guidance device, which comprises a seeker head and a transducer array; the front end surface of the seeker head is a circular plane; The rear end is an electronic warehouse and adopts a cylindrical structure; the diameter of the front end surface of the seeker is smaller than the diameter of the electronic warehouse; a transition section is set between the front end surface of the seeker head and the electronic warehouse; the transition section adopts a streamlined arc segment; the transducer The base array includes a front-end plane array and a side sparse circular array; the front-end plane array includes a plurality of transducer array elements arranged on the front end of the seeker and arranged according to the principle of symmetry; the side sparse circular array includes a transition element. A plurality of transducer array elements are arranged at equal intervals in the circumferential direction of the segment, and each transducer array element in the side sparse circular array faces forward. By optimizing the array and compact layout of the transducer base array, the invention is convenient to fully obtain the maximum space gain in the limited volume space of the small-diameter acoustic guiding device.

Description

technical field [0001] The invention belongs to the technical field of torpedo self-guidance engineering, in particular to a light torpedo acoustic guidance device and a light torpedo acoustic guidance method based on the light torpedo acoustic guidance device. Background technique [0002] When the torpedo is working, it mainly detects the target through the guidance device. After the signal is amplified and calculated, the relative position and speed relationship between the torpedo and the target is calculated. After the attack trajectory is calculated by the triangular principle, the control system transmits the signal to the The rudder surface controls the trajectory of the torpedo to attack the target. Therefore, the guidance device is the eyes and ears of the torpedo moving underwater, and the acoustic guidance device of the torpedo is a system that automatically forms guidance instructions through the acoustic energy of the target through the underwater acoustic tran...
