Description

Sonar System for Submarine

The present invention relates to a sonar system of a submarine, in particular, the sonar of the submarine that can measure the angle and distance to the vertical component by operating the addition of a foldable manual sonar to the function manual sonar by switching the function of the PRS in the vertical direction It's about the system.

Sonar comes from sound navigation and ranging, which means narrowly the hydrophone and sound detector. Electromagnetic waves and radar waves, such as visible light, are not transmitted to the sea, so they are expressed using ultrasonic waves. The speed of the sound transmitted in the sea varies depending on the situation of the sea, but it is about 1,500 m / s.

There are two types of sonar: active or active sonar that makes an object by sounding itself, such as an acoustic detector type, and passive or passive sonar, which measures sound from a sound source and expresses it, such as a hydrophone type. The former includes an acoustic detector and an acoustic side detector, which emits ultrasonic waves as short intermittent sounds and measures the distance to the object by measuring the time it takes to hit the object and reflect it back. It also detects the direction by rotating the transmitter (送波器). It is actually the same as radar's PPI scope method, and the distance is measured on the CRT and the bearings are engraved on the circumference so that the scan line rotates with the rotation of the transmitter. Objects appear as light spots to detect distance and orientation. Acoustic side detectors, fish finders, submarines and mines for sonar detection, and side looking sonars that detect the structure of the seabed are a type of sonar in which the main body emits sound waves.

The sonar of these submarines is the most important means of identifying enemies, taking into account the nature of their navigation in the water. In addition, the sonar of the submarine has a passive sonar, an intercept sonar, a passive ranging sonar, a flank array sonar, and a line array in consideration of detection and operational characteristics. It can be classified into Towed Array Sonar, Active Sonar, or Mine Avoidance Sonar. These sonars can be used to derive the horizontal orientation and distance to the target from the submarine. The target's orientation is detected through a water bath, a waterproof station, a side array station, or an array of towing units, and the distance of the target is controlled by the PRS installed in the longitudinal direction of the submarine or by TMA (Target Motion Analysis). Can be identified. However, the sonar of a conventional submarine cannot be used to measure the vertical orientation and distance of a target.

The present invention has been conceived under the above-mentioned background, the submarine sonar to measure the angle and distance to the vertical component by operating by adding a folding manual sonar to the function manual sonar by switching the function of the PRS in the vertical direction The purpose is to provide a system.

The system according to an embodiment of the present invention for achieving the above object, as a sonar system of the submarine,

A function manual sonar for performing horizontal detection of the target;

A collapsible manual sonar installed under the submarine capable of receiving a target sound by reaching a predetermined depth in sea water;

A winch used to lower the foldable manual sonar to a predetermined depth of operation or to lift the foldable manual sonar at a target depth of underwater into the submarine;

A motor for unfolding the collapsible manual sonar in a folded state;

An anchor to keep the unfolded collapsible manual sonar central;

A sonar cabinet configured to perform signal processing on the target sound received from the function manual sonar and the collapsible manual sonar; And

It provides a sonar system of a submarine comprising a sonar pocket for storing the manual folding sonar.

According to the present invention, the vertical detection of the target is possible in the operation of the submarine, the horizontal detection of various depths is possible, and the effective operation is possible even in the depth operation of the submarine's water operation or periscope.

1 (a) and (b) show schematic side and front views of a submarine with a sonar system according to one embodiment of the invention.

Hereinafter, a sonar system of a submarine according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in the figure, the sonar system of the present invention has a function manual sonar 20 for performing horizontal detection of a target, and a collapsible manual installed under a submarine capable of receiving a target sound by reaching a predetermined depth in seawater. Sonar 60, a winch 40 used to lower the collapsible manual sonar 60 to a predetermined depth of operation or to lift the collapsible manual sonar 40 at a submerged target depth into the submarine. A sonar cabinet 100 which performs signal processing for a target sound received from a motor (not shown), a function manual sonar, or a foldable manual sonar that unfolds the folded folding sonar 60 'in a true state; Anchor 80 to maintain the unfolded folding manual sonar 60 and a sonar pocket 90 to hold the manual folding sonar.

In addition, the collapsible manual sonar 60 is connected by a winch cable 61 so that the collapsible manual sonar 60 is deployed in seawater of a predetermined depth. In addition, the winch 40, the sonar cabinet 100, the sonar cabinet 100 and the functional manual sonar 20 are connected by signal cables 41 and 101, the signal cable 41 is a sonar signal cable and winch for convenience Do not distinguish the control cable as one cable.

Next, the operation of the sonar system of the present invention configured as described above will be described.

A functional manual sonar 20 located at the top of the function performs horizontal detection of the target at the horizontal position of the submarine, and the target sound received from the function water sonar 20 is transmitted to the sonar cabinet 100 via the cable 101. Delivered to identify the target tone.

On the other hand, when the target target is at the vertical depth of the predetermined underwater position, the collapsible manual sonar 60 is deployed by the winch 40 to the target depth. Of course, the motor is used to unfold the folding manual sonar 60 at this time. And the anchor 80 allows the collapsible manual sonar 60 to be centered at the target position.

The deployed passive collapsible passive sonar 60 'receives target sounds from a target target and is delivered to the sonar cabinet 100 through a cable 61 to identify the target sounds through signal processing.

According to the present invention described above, the vertical detection of the target is possible in the operation of the submarine, the horizontal detection of various depths is possible, and the effective operation is possible even in the depth operation of the submarine's water operation or periscope. .

So far, a sonar system of a submarine according to an embodiment of the present invention has been described with reference to the drawings, but this description is for illustrative purposes, and it should be understood that the present invention is not intended to limit the present invention. Rather than as a detailed description, it is specified by the appended claims, which are intended to be included within the scope of the present invention all changes or modifications derived from the meaning and scope and equivalent concepts thereof.
