In general, a track tracking torpedo is a weapon that shoots down a trap by detecting fine bubbles generated in a track at a high frequency of several hundred KHz bands, unlike conventional acoustic tracking torpedoes. That is, the track tracking torpedo tracks the trap by using a phenomenon in which the radio frequency radiates to the track and the emitted radio frequency is attenuated by the track. Therefore, there is a problem in that the survival rate of the ship can not be increased because the existing acoustic deception cannot deceive the track tracking torpedo.

As a related technique, a method of deceiving a track-tracking torpedo has been proposed by making the tracks produced by the trap similarly to deceive the track-tracking torpedo. However, this technique is a technique in which the deceit creates a drop of air to create a track similar to the ship's track, leading the track torpedo away from the ship (a friendly ship).

Is a block diagram illustrating the operation of the track tracking torpedo response system according to an embodiment of the present invention.

As shown in FIG. 1, the track tracking torpedo response system 1000 includes a first buoy 100 and a second buoy 200.

The first buoy 100 is maintained on the track of the ship and transmits the navigation information of the track tracking torpedo to the second buoy which will be described later. Here, the term "self-ship" refers to a friendly vessel, and the navigation information is a concept including the position, movement direction, and speed of the track tracking torpedo.

The first buoy 100 includes a track keeping apparatus 110, a posture maintaining apparatus 120, and a track tracking signal detecting sensor 130. The track holding device 110 prevents the tracks of the own box from disappearing so that the tracks of the own box are maintained. When the ship sails at sea, microscopic bubbles are generated along its path. The track tracking torpedo tracks the ship by detecting such tracks, and in the present invention, since the track tracking torpedoes correspond to the track tracking torpedoes as they are, the track keeping device does not disappear. 110 allows the wake of the ship to continue. A more detailed description of the track holding device 110 will be described later.

The posture maintaining device 120 is a device provided to prevent the first buoy 100 from being separated from the wake of the own box. The first buoy 100 should be located on the track while keeping the track of the own ship through the above-described track holding device 110.

The track tracking sensor unit 121 emits a high frequency wave of the magnetic box and receives a degree of scattering of the high frequency wave by the track. That is, the operation of the track tracking sensor 121 is similar to the track tracking torpedo detecting the track of the ship. The plurality of sensors provided in the track tracking sensor unit 121 are located in the water spaced apart from the first buoy 100 by a predetermined distance, and radiate high frequency waves to the sea level in these sensors, and the radiated high frequency waves are reflected by the sea level or the track. Receive echoes. At this time, when the high frequency reaches the fine bubbles of the wake, the received high frequency is attenuated by scattering. When the high frequency reaches the sea level off the wake, the received high frequency is attenuated by scattering. Therefore, it is determined whether the first buoy 100 deviates from the track by using the attenuation degree of the high frequency signal received by the plurality of sensors provided in the track tracking sensor unit 121.

The posture determination unit 122 analyzes the high frequency received by the track tracking sensor unit 121 to determine whether the first buoy is separated from the track of the own box. That is, it is detected whether the first buoy 100 is located on the track by detecting the degree to which the high frequency is attenuated by scattering by the microbubbles of the track.

The buoy driving unit 123 moves the first buoy 100 to be located on the wake of the own box according to the determination result of the posture determination unit 122.

The track tracking signal detection sensor 130 is a device for detecting a signal emitted from the track tracking torpedo to detect the track of the own ship. The track tracking signal detection sensor 130, for example, consists of two pairs to detect high frequency radiation emitted from the track tracking torpedo to detect navigation information of the track tracking torpedo. That is, as shown in Figure 3, the operation unit 140 of the first buoy 100 analyzes the signal emitted from the track tracking torpedo detected by the track tracking signal detection sensor 130 to navigate information of the track tracking torpedo Calculate The calculated information is transmitted to the reception antenna 230 of the second buoy 200 through the transmission antenna 150.

The second buoy 200 is provided to capture the track tracking torpedo by receiving the navigation information of the track tracking torpedo transmitted by the first buoy 100.

As shown in FIG. 1, the second buoy 200 includes a track holding device 210, a posture maintaining device 220, a receiving antenna 230, and a catching net device 240. Here, the track holding device 210 and the posture maintaining device 220 perform the same functions as those provided in the first buoy 100, and thus the description thereof will be omitted, and the reception antenna 230 may be omitted. It is not necessary to use a reception antenna according to a known technique to be provided to receive the navigation information of the track tracking torpedo transmitted from one buoy 100, a separate description will be omitted.

The catch net device 240 is provided in the second buoy 200 as a means for catching the track tracking torpedo. The catch net device 240 is preferably located on the progress path of the track tracking torpedo. The second buoy 200 is provided with an adjusting means for adjusting the position of the capture netting device 240 based on the navigation information of the track tracking torpedo transmitted from the first buoy 100, and being captured by the adjusting means. Adjust the position of the device 240 (exactly at its depth).

4 is a diagram illustrating the overall operation of the track tracking torpedo response system according to an embodiment of the present invention.

As shown in FIG. 4, the magnetic box 300 sequentially drops the first buoy 100 and the second buoy 200 onto the track to correspond to the track tracking torpedo 500 that tracks its track. . As described above, the first buoy 100 allows the track tracking torpedo 500 to accurately track the track using the track holding device 110 in the state of maintaining the track of the ship as described above. At the same time, it detects the high frequency emitted by the track tracking torpedo 500 within the available detection range of the track tracking signal detection sensor 130 to generate navigation information of the track tracking torpedo 500 and transmits it to the second buoy 200. .

The second buoy 200 captures the catch net device 240 provided to capture and strike the track tracking torpedo 500 based on the navigation information of the track tracking torpedo 500 transmitted by the first buoy 100. Install and adjust. At this time, the second buoy 200 cooperates with the track tracking of the track tracking torpedo 500 by using the track holding device 210 as in the first buoy 100 and uses the posture maintaining device 220. To remain on the wake of the magnetic box 300.

Herein, a detailed description of the configuration of the track holding device provided in the first and second buoys and the trapping device provided in the second buoy are described.

5 is a view showing in detail to the track holding device used in the present invention.

As shown in FIG. 5, the track holding apparatus 110 includes a water pump 111, a bubble generator 112, a float feeder 113, and a combination thrower 114.

Pump 111 is supplied to the bubble generator 112 to the inflow of sea water. At the same time, the float feeder 113 supplies a float such as mud or earth and sand to the bubble generator 112. Here, the reason for supplying the suspended matter is that bubbles generated in the water are first extinguished within a relatively short time, but when the suspended matter is supplied to the microbubbles, the microbubbles and the suspended matter are combined to maintain the bubbles for a relatively long time. Another reason is that the float itself can induce high frequency scattering of the track tracking torpedo, thereby preventing the track tracking failure of the track tracking torpedo.

The bubble generator 112 generates bubbles by using a propeller rotating in response to the seawater and the floats supplied from the water pump 111 and the float feeder 113. The combination of bubbles and floats thus produced is thrown onto the wake of the ship via the combination thrower 114. Since the operation of the track holding device 110 has been described above, a description thereof will be omitted.

6 is a view illustrating in detail the capture net device used in the present invention.

As shown in FIG. 6, the catch net device 240 is a device for capturing the track tracking torpedo and further blasting the captured torpedo. The catch net device 240 includes a screw lanyard 242, a mesh 241, explosives 243, and a weight 245.

Screw hook 242 is a device for stopping the rotation of the screw to catch the screw propelling the track tracking torpedo. When the screw of the track tracking torpedo is caught by the screw catching strap 242, the tracking of the track tracking torpedo is restricted, and the track tracking torpedo is captured in the mesh 241. The weight 245 allows the catching net device 240 to be fixed at a certain depth and also to keep the mesh 241 unfolded without being folded by the current. The explosives 243 are disposed in the net 241 and are provided to cause a hard kill by detonating the captured track tracking torpedo. Here, it is preferable that the capture net device 240 separates the capture net device 240 from the second buoy before detonating the explosives 243.
