Description

Technical Field

[0001] This invention belongs to the field of ship technology, and more specifically, relates to a ship cooperative protection system. Background Technology

[0002] Target ships, as conventional targets for missile firing, are basically decommissioned / retired vessels. Land tests often use high-power radar, electromagnetic interference and other equipment to interfere with missiles and cause them to deviate from their intended trajectory, thus achieving the effect of missing the target. However, there is currently no mature method to test the anti-interference performance of missiles in sea tests. During escort operations, the fleet sails near merchant ships and uses helicopters to patrol, completing the protection of the sea and airspace and protecting the personnel on the merchant ships from Somali pirate attacks. However, the protection cost is too high. (1) Target ships involve a large number of personnel and a huge amount of engineering work. Long-distance towing is difficult and the risk of maritime operations is high. At the same time, the characteristics of ship targets that target ships can simulate are limited. They cannot simulate speed and cannot be compatible with playing the role of larger ships. They have poor versatility and little significance for actual combat training. (2) During target firing training, conventional missile firing tests are carried out on single types of target ships, buoys and other single scenarios, which cannot reproduce the electromagnetic environment of the real sea battlefield. Unpowered target ships are often towed by large ships. After being towed to a designated sea area, they are separated from the mother ship and wait to be detected and destroyed by ship radar. (3) There are currently no advanced technical means to create a complex electromagnetic environment at sea, and it is impossible to detect the hit rate of missiles in a complex electromagnetic environment. (4) Protecting manned ships is extremely costly and risky. During the protection process, the attack and self-defense capabilities of the protected ships and the commander's combat command capabilities in a changing situation are put to the test.

[0003] In existing technologies, when facing dangerous situations such as missile attacks or penetration, and when the missile is far from the ship, the conventional operation is to first use passive jamming or other defensive weapons to release flammable, high-temperature, and high-brightness platinum bars to interfere with the missile's flight path and detonation time in advance. If the jamming measures still fail to stop the missile attack, and the missile gets closer to the ship, the conventional operation is to activate weapons such as the Type 1130 self-defense artillery to directly and continuously fire at the incoming missile, which is very likely to cause casualties to personnel on manned ships.

[0004] Among the existing technologies is a technology entitled "Path Planning Method and System for Unmanned Surface Vessels at Sea" with publication number "110244720A". The method of this technology includes: generating a grid map of the sea area to be patrolled; generating random patrol paths for multiple unmanned surface vessels in the grid map; acquiring historical patrol data of each unmanned surface vessel; predicting the estimated arrival time of each unmanned surface vessel when passing through each grid in the patrol path; determining whether the patrol path of each unmanned surface vessel has overlapping grids with the patrol paths of other unmanned surface vessels; if so, determining whether the difference between the estimated arrival times of multiple unmanned surface vessels passing through the same grid is greater than a first threshold; if the difference between the estimated arrival times of two unmanned surface vessels passing through the same grid is less than or equal to the first threshold, adjusting the patrol path of one unmanned surface vessel so that the patrol path of the unmanned surface vessel avoids the grid.

[0005] However, this technology does not address the technical issues and solutions of this application. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a ship cooperative protection system that is simple in structure and can effectively avoid being directly hit by anti-ship missiles and protect the navigation safety of manned ships by enabling them to sail in formation and cooperate with unmanned surface vessels and manned ships.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0008] This invention relates to a ship cooperative protection system, comprising an unmanned surface vessel (USV) and a manned ship. The USV is equipped with an electromagnetic wave reflection enhancer and a radiation load and an angle reflection carrier load. The USV is wirelessly connected to the ship's deck command terminal and simultaneously wirelessly connected to a land-based command terminal.

[0009] The electromagnetic wave reflection enhancer is installed on the top of the superstructure of the unmanned surface vessel.

[0010] The formation navigation modes of the unmanned surface vessels and manned ships include the two-ship formation navigation mode, the three-ship formation navigation mode in a triangular pattern, the three-ship formation navigation mode in a crisscross pattern, the four-ship diamond formation navigation mode, the four-ship square formation navigation mode, and the six-ship square formation navigation mode.

[0011] The unmanned surface vessel and manned ship formation sail synchronously, and when they sail synchronously, a formation center is formed between them.

[0012] The aforementioned two-ship formation navigation mode includes one unmanned surface vessel and one manned ship; the three-ship triangular formation navigation mode includes two unmanned surface vessels and one manned ship; and the three-ship zigzag formation navigation mode includes two unmanned surface vessels and one manned ship.

[0013] The four-ship diamond formation navigation mode includes three unmanned surface vessels and one manned ship; the four-ship square formation navigation mode includes three unmanned surface vessels and one manned ship; and the six-ship square formation navigation mode includes five unmanned surface vessels and one manned ship.

[0014] When unmanned surface vessels (USVs) and manned ships sail in a synchronized formation, in a two-ship formation, one manned ship sails in front and one USV sails behind; in a three-ship formation, one manned ship sails in front and two USVs sail behind; in a three-ship formation, one USV sails to the left of the manned ship and the other USV sails to the right of the manned ship.

[0015] When unmanned surface vessels (USVs) and manned ships sail in a synchronized formation, in a four-ship diamond formation, the manned ship sails in front, two USVs sail in the center (one on the left and one on the right), and one USV sails behind. In a four-ship square formation, one USV and one manned ship sail in the left (one in front and one behind), and two USVs sail in the right. In a six-ship square formation, one manned ship and one USV sail in the center (one in front and one behind), two USVs sail in the left (one in front and one behind), and two USVs sail in the right (one in front and one behind).

[0016] In a two-ship formation, the formation center is the geometric center of the straight-line distance between the unmanned surface vessel and the manned vessel. In a three-ship formation (three ships in a triangular shape), the formation center is the geometric center of the triangle formed by the three ships. In a three-ship formation (three ships in a zigzag shape), the formation center is the geometric center of the straight-line distance between two adjacent ships. In a four-ship diamond formation, the formation center is the geometric center of the diamond formed by the four ships. In a four-ship square formation, the formation center is the geometric center of the square formed by the four ships. In a six-ship square formation, the formation center is the geometric center of the square formed by the six ships.

[0017] This invention also relates to a simple method for coordinated ship protection, which effectively avoids direct hits by anti-ship missiles and protects the navigation safety of manned ships through coordinated navigation of unmanned surface vessels and manned vessels in formation. The protection steps of the method are as follows:

[0018] S1. The unmanned surface vessel (USV) and manned ship are used for formation navigation. The USV is equipped with an electromagnetic wave reflector 3 and a radiation load and a corner reflection carrier load. The USV is wirelessly connected to the ship's deck command terminal and simultaneously wirelessly connected to the land command terminal.

[0019] S2. When unmanned surface vessels and manned ships are sailing in formation, they shall sail in one of the following formation modes: two ships ahead and behind, three ships ahead and behind in a triangular formation, three ships in a zigzag formation, four ships in a diamond formation, four ships in a square formation, and six ships in a square formation.

[0020] The working principle and beneficial effects of the technical solution adopted in this invention are as follows:

[0021] The ship-to-ship cooperative protection system described in this invention features an electromagnetic wave reflector amplified on the unmanned surface vessel (USV). By enhancing the measured RCS (Radar Cross Section), the USV is misidentified by enemy radar as a large manned vessel, thus deceiving the enemy and protecting the manned vessel. The USV's electromagnetic wave reflector amplification is mounted on the top of the superstructure, maximizing its coverage and creating a virtual vessel with the largest possible range, thus maximizing the amplification's effectiveness. The enemy, mistaking the USV for a large manned surface vessel, launches a fire attack. Once the USV is attacked, the enemy surface vessel's position is exposed, providing crucial clues for subsequent defense and attack. The USV can be commanded and operated via the ship's deck command terminal or remotely controlled via a land-based command terminal. Supporting both command and control methods avoids problems such as loss of signal and inability to control the USV at long distances. When the USV is far from the coastline, operation via the ship's deck command terminal is more suitable, allowing the crew to directly observe and operate the USV's status. Figure 2As shown, the unmanned boat carrying a corner reflector payload will degrade the stealth performance of the unmanned boat and increase the RCS value of the small unmanned boat to that of a large surface ship, which can greatly increase the probability of being detected by the enemy's radar. When the unmanned boat carries a radiation payload, a complex electromagnetic environment will be formed around the formation of the unmanned boat and manned ship, interfering with the flight direction and trajectory of the missile and ultimately inducing the missile to change the target point. If a manned ship in front of an unmanned boat is not detected, or is detected by radar as the same ship as the unmanned boat, or the unmanned boat maneuvers to block the manned ship to prevent the manned ship from being directly irradiated by the radar, the enemy's anti-ship missile will directly attack the unmanned boat. Therefore, it can effectively protect the safety of the manned ship and prevent the manned ship from being directly hit by the anti-ship missile. In this way, the large manned ship can be camouflaged by the low-cost unmanned boat. By forming a formation with the low-cost unmanned boat and the manned ship, and the unmanned boat and the manned ship form a formation through different numbers and configurations, all-round protection of the manned ship can be achieved. The unmanned boat has its own power and does not need to be matched with a tow rope or towing device. The navigation process no longer depends on the towing operation of the manned ship, which improves the navigation speed. The unmanned boat has its own formation communication device and can quickly change the formation shape under the unified command of the manned ship according to the actual situation to adapt to the ever-changing sea battlefield environment. At the same time, the unmanned boat 1 can be used as a target boat, carrying a radiation payload, etc., so as to create a complex offshore electromagnetic environment to help the actual test of the missile performance.

Detailed implementation manners

[0036] The following further describes in detail the specific implementation manners of the present invention, such as the shapes, structures of the components involved, the mutual positions and connection relationships between the parts, the functions and working principles of the parts, etc., by describing the embodiments in conjunction with the drawings:

[0037] As shown in the attached Figure 1 and attached Figure 2 figures, the present invention is a ship cooperative protection system, including an unmanned boat 1 and a manned ship 2. An electromagnetic wave reflection enhancer 3 is installed on the unmanned boat 1. A radiation payload 4 and a corner reflector carrier payload 5 are simultaneously installed on the unmanned boat 1. The unmanned boat 1 is wirelessly connected to the shipboard command terminal 6 of the manned ship 2, and the unmanned boat 1 is simultaneously wirelessly connected to the land command terminal 7. The electromagnetic wave reflection enhancer 3 is installed at the top position of the superstructure 8 of the unmanned boat 1. With the above structure, in view of the deficiencies in the prior art, an improved technical solution is proposed. An electromagnetic wave reflection enhancer is installed on the unmanned boat. By enhancing the measured value of the RCS (radar cross section), the unmanned boat 1 is judged by the enemy's radar as a large manned ship, so as to deceive the enemy and protect the manned ship. As Figure 1As shown, the dashed line represents the image of the unmanned surface vessel (USV) after radar detection, i.e., the coverage area of ​​the virtual vessel 10, while the solid line represents the actual small USV 1. The USV's electromagnetic wave reflector is installed on the top of the superstructure, maximizing its coverage area and creating the largest possible virtual vessel 10, thus best utilizing the reflector's effectiveness. Figure 1 As shown, the dashed line represents the virtual ship size detected and identified by enemy radar for the unmanned surface vessel (USV). The enemy mistakes USV 1 for a large manned surface vessel (USV 2) and launches a fire attack on USV 1. Once USV 1 is attacked, it means that the position of the enemy surface vessel is exposed, providing important clues for our subsequent organization of defense and attack. Figure 2 As shown, the unmanned surface vessel (USV) 1 can be commanded and operated via the shipboard command terminal 6 of the manned vessel 2, or remotely controlled via the land-based command terminal 7. Supporting both command and remote control methods avoids problems such as loss of signal and inability to control USV 1 at long distances. When USV 1 is far from the coastline, operation via the shipboard command terminal of the manned vessel is more suitable, allowing the crew to directly observe and operate the USV's status visually. Figure 2 As shown, the unmanned surface vessel (USV) carrying a corner reflector payload 5 will reduce the stealth performance of USV 1, increasing its RCS value from that of a small surface vessel to that of a large surface ship, significantly increasing the probability of detection by enemy radar. USV 1 also carries a radiation payload 4, creating a complex electromagnetic environment around the USV 1 and manned vessel 2 formation, interfering with missile flight direction and trajectory, and ultimately inducing the missile to change its target point. For example... Figure 3As shown, the dashed line represents the size of the ship detected and identified by enemy radar as unmanned surface vessel 1 (USV1). If a manned ship 2 ahead of USV1 is not detected, or is detected by radar as USV1 and manned ship 2 being the same vessel, or if USV1 maneuvers to shield manned ship 2 from direct radar illumination, then enemy anti-ship missiles will directly attack USV1. Therefore, it effectively protects the safety of manned ship 2, preventing it from being directly hit by anti-ship missiles. In this way, a large manned ship 2 can be camouflaged using a low-cost USV1. By forming formations with manned ships using low-cost USV1 and different numbers and configurations of USVs and manned ships, all-around protection for manned ship 2 can be achieved. USV1 is self-powered and does not require tow ropes or towing devices, eliminating the need for towing by manned ship 2 during navigation, thus increasing its speed. The unmanned surface vessel (USV) 1 is equipped with a formation communication device, enabling it to rapidly change formation under the unified command of the manned vessel 2, adapting to the ever-changing maritime battlefield environment and ensuring the safety of the manned vessel 2. Simultaneously, USV 1 can serve as a target vessel, carrying radiation payloads 4, thereby creating a complex maritime electromagnetic environment to aid in the practical testing of missile performance. The ship-to-ship cooperative protection system described in this invention has a simple structure and can effectively avoid direct hits by anti-ship missiles by coordinating the formation navigation of USVs and manned vessels, thus protecting the safety of manned vessels.

[0038] The unmanned surface vessel (USV) 1 and manned vessel 2 can form formations including a two-ship formation, a three-ship triangular formation, a three-ship zigzag formation, a four-ship diamond formation, a four-ship square formation, and a six-ship square formation. This structure allows for low-cost formation between the USV 1 and manned vessels, with varying numbers and configurations of USVs and manned vessels achieving formation coverage and providing comprehensive protection for the manned vessel 2. The USV 1 is self-powered and requires no tow ropes or towing devices, eliminating reliance on towing by the manned vessel 2 and increasing its speed.

[0039] The unmanned surface vessel 1 and the manned ship 2 sail in formation and synchronize. When the unmanned surface vessel 1 and the manned ship 2 sail in formation and synchronize, a formation center 9 is formed between the unmanned surface vessel 1 and the manned ship 2.

[0040] The aforementioned two-ship formation navigation mode includes one unmanned surface vessel 1 and one manned ship 2; the three-ship triangular formation navigation mode includes two unmanned surface vessels 1 and one manned ship 2; and the three-ship zigzag formation navigation mode includes two unmanned surface vessels 1 and one manned ship 2.

[0041] The four-ship diamond formation navigation mode includes three unmanned surface vessels 1 and one manned ship 2; the four-ship square formation navigation mode includes three unmanned surface vessels 1 and one manned ship 2; and the six-ship square formation navigation mode includes five unmanned surface vessels 1 and one manned ship 2.

[0042] Unmanned surface vessel 1 and manned ship 2 sail in formation. In the two-ship formation mode, one manned ship 2 sails in front and one unmanned surface vessel 1 sails behind. In the three-ship formation mode, one manned ship 2 sails in front and two unmanned surface vessels 1 sail behind. In the three-ship formation mode, one unmanned surface vessel 1 sails to the left of manned ship 2 and the other unmanned surface vessel 1 sails to the right of manned ship 2.

[0043] When the unmanned surface vessel 1 and the manned ship 2 are sailing in a formation, the manned ship 2 is in front, the two unmanned surface vessels 1 are on the left and right sides in the center, and the unmanned surface vessel 1 is behind. When the four ships are in a square formation, the unmanned surface vessel 1 and the manned ship 2 are in front and behind each other on the left, and the two unmanned surface vessels 1 are on the right. When the six ships are in a square formation, the manned ship 2 and the unmanned surface vessel 1 are in front and behind each other in the center and front and behind each other, the two unmanned surface vessels 1 are in front and behind each other on the left, and the two unmanned surface vessels 1 are in front and behind each other on the right.

[0044] In the two-ship formation navigation mode, the formation center 9 is the geometric center of the straight-line distance between the unmanned surface vessel 1 and the manned ship 2. In the three-ship triangular formation navigation mode, the formation center 9 is the geometric center of the triangle formed by the three ships. In the three-ship zigzag formation navigation mode, the formation center 9 is the geometric center of the straight-line distance between two adjacent ships. In the four-ship diamond formation navigation mode, the formation center 9 is the geometric center of the diamond formed by the four ships. In the four-ship square formation navigation mode, the formation center 9 is the geometric center of the square formed by the four ships. In the six-ship square formation navigation mode, the formation center 9 is the geometric center of the square formed by the six ships.

[0045] The ship cooperative protection system described in this invention has the following different navigation modes:

[0046] like Figure 4 As shown, an unmanned surface vessel (USV) and a manned ship are sailing in a two-ship formation, one in front of the other. The dotted line represents the size of the ship detected and identified by enemy radar. The manned ship in front of the USV is also detected by the enemy. The enemy's anti-ship missile target, originally the USV, has now shifted to the geometric center of the straight-line distance between the USV's and the manned ship's geometry. This effectively protects the manned ship from direct hits by the anti-ship missile.

[0047] Two unmanned surface vessels (USVs) and one manned ship sailed in a triangular formation, synchronized. If only one USV was detected by the enemy, then... Figure 3 As shown, enemy anti-ship missiles are directly attacking a single unmanned surface vessel. If all manned ships and two unmanned surface vessels are detected by enemy radar, then... Figure 5 As shown, the enemy's anti-ship missiles are positioned at the geometric center of the triangle formed by the three ships, thus effectively protecting the manned ships and preventing them from being directly hit by the anti-ship missiles.

[0048] Two unmanned surface vessels (USVs) and one manned ship sailed in a V-formation, synchronized. If only one USV was detected by the enemy, then... Figure 6 As shown, enemy anti-ship missiles are directly attacking a single unmanned surface vessel. If only one unmanned surface vessel and one manned vessel are detected by the enemy, such as... Figure 7 , Figure 8 As shown, the enemy's anti-ship missile's attack position is located at the geometric center of the straight-line distance between the two ships, thus effectively protecting the safety of manned ships and preventing them from being directly hit by anti-ship missiles.

[0049] Three unmanned surface vessels and one manned ship sailed in synchronized formations, forming diamonds, squares, etc. For example... Figure 9 , Figure 10 As shown, if both manned ships and two unmanned boats are detected by enemy radar, then... Figure 4 As shown, the anti-ship missile's attack position is located at the geometric center of the diamond-shaped formation formed by the four ships, which can effectively protect the safety of manned ships and prevent them from being directly hit by the anti-ship missile.

[0050] Three unmanned surface vessels and one manned ship sailed in synchronized formations, forming diamonds, squares, etc. For example... Figure 11 As shown, if both manned ships and two unmanned boats are detected by enemy radar, then... Figure 5 As shown, the anti-ship missile's attack position is located at the geometric center of the square formed by the four ships, thus effectively protecting the safety of manned ships and preventing them from being directly hit by the anti-ship missile.

[0051] This invention also relates to a simple method for coordinated ship protection, which effectively avoids direct hits by anti-ship missiles and protects the navigation safety of manned ships through coordinated navigation of unmanned surface vessels and manned vessels in formation. The protection steps of the method are as follows:

[0052] S1. An unmanned surface vessel (USV) 1 and a manned ship 2 are arranged in formation. USV 1 is equipped with an electromagnetic wave reflector booster 3, a radiation payload 4, and a corner reflector carrier payload 5. USV 1 is wirelessly connected to the deck command terminal 6 of manned ship 2 and simultaneously wirelessly connected to a land-based command terminal 7. S2. When USV 1 and manned ship 2 are arranged in formation, they will follow one of the following formation modes: a two-ship formation ahead and behind, a three-ship triangular formation, a three-ship zigzag formation, a four-ship diamond formation, a four-ship square formation, or a six-ship square formation. In this way, the electromagnetic wave reflector booster on the USV enhances the measured RCS (Radar Cross Section), making USV 1 appear as a large manned ship to enemy radar, thus deceiving the enemy and protecting the manned ship. Different formation modes are adopted according to the actual protection needs of the manned ship. During the navigation process, the USV protects the manned fleet. The enemy mistook unmanned surface vessel 1 for a large manned surface vessel 2 and launched a fire attack on it. Once unmanned surface vessel 1 was attacked, it meant the location of the enemy surface vessel was exposed, providing crucial clues for our subsequent defense and attack operations. For example... Figure 2 As shown, the unmanned surface vessel (USV) 1 can be commanded and operated via the shipboard command terminal 6 of the manned vessel 2, or remotely controlled via the land-based command terminal 7. Supporting both command and remote control methods avoids problems such as loss of signal and inability to control USV 1 at long distances. When USV 1 is far from the coastline, operation via the shipboard command terminal of the manned vessel is more suitable, allowing the crew to directly observe and operate the USV's status visually. Figure 2 As shown, the corner reflector payload 5 carried by the unmanned surface vessel (USV) will reduce the stealth performance of USV 1, increasing its RCS value from that of a small surface vessel to that of a large surface ship, thus significantly increasing the probability of being detected by enemy radar. The radiation payload 4 carried by USV 1 creates a complex electromagnetic environment around the USV 1 and manned vessel 2 formation, interfering with the missile's flight direction and trajectory, ultimately inducing the missile to change its target point.

[0053] The ship cooperative protection system described in this invention involves installing an electromagnetic wave reflection enhancer on the unmanned surface vessel (USV). By amplifying the measured RCS (Radar Cross Section), the USV is misidentified by enemy radar as a large manned vessel, thus deceiving the enemy and protecting the manned vessel. For example... Figure 1 As shown, the dashed line represents the image of the unmanned surface vessel (USV) after radar detection, i.e., the coverage area of ​​the virtual vessel 10, while the solid line represents the actual small USV 1. The USV's electromagnetic wave reflector is installed on the top of the superstructure, maximizing its coverage area and creating the largest possible virtual vessel 10, thus best utilizing the reflector's effectiveness. Figure 1As shown, the dashed line represents the virtual ship size detected and identified by enemy radar for the unmanned surface vessel (USV). The enemy mistakes USV 1 for a large manned surface vessel (USV 2) and launches a fire attack on USV 1. Once USV 1 is attacked, it means that the position of the enemy surface vessel is exposed, providing important clues for our subsequent organization of defense and attack. Figure 2 As shown, the unmanned surface vessel (USV) 1 can be commanded and operated via the shipboard command terminal 6 of the manned vessel 2, or remotely controlled via the land-based command terminal 7. Supporting both command and remote control methods avoids problems such as loss of signal and inability to control USV 1 at long distances. When USV 1 is far from the coastline, operation via the shipboard command terminal of the manned vessel is more suitable, allowing the crew to directly observe and operate the USV's status visually. Figure 2 As shown, the unmanned surface vessel (USV) carrying a corner reflector payload 5 will reduce the stealth performance of USV 1, increasing its RCS value from that of a small surface vessel to that of a large surface ship, significantly increasing the probability of detection by enemy radar. USV 1 also carries a radiation payload 4, creating a complex electromagnetic environment around the USV 1 and manned vessel 2 formation, interfering with missile flight direction and trajectory, and ultimately inducing the missile to change its target point. For example... Figure 3 As shown, the dashed line represents the size of the ship detected and identified by enemy radar as unmanned surface vessel 1 (USV1). If a manned ship 2 ahead of USV1 is not detected, or is detected by radar as USV1 and manned ship 2 being the same vessel, or if USV1 uses maneuvering to shield manned ship 2 from direct radar illumination, then enemy anti-ship missiles will directly attack USV1. Therefore, it effectively protects the safety of manned ship 2, preventing it from being directly hit by anti-ship missiles. In this way, a large manned ship 2 can be camouflaged using a low-cost USV1. By forming formations with manned ships using low-cost USV1, and by using different numbers and configurations of USVs and manned ships in different formations and employing different navigation modes, the enemy can be effectively confused, achieving all-round protection for manned ships. USV1 is self-powered and does not require tow ropes or towing devices, eliminating the need for towing by manned ships 2 during navigation, thus increasing its speed. The unmanned surface vessel 1 is equipped with a formation communication device, enabling it to rapidly change formation under the unified command of the manned ship 2, adapting to the ever-changing maritime battlefield environment and ensuring the safety of the manned ship 2. Simultaneously, the unmanned surface vessel 1 can serve as a target vessel, carrying radiation payloads 4, thereby creating a complex maritime electromagnetic environment to aid in the practical testing of missile performance.
