Description

Technical Field

[0001] The present invention relates to the technical field of underwater robot formation, and in particular to a method for underwater unmanned submersible vehicle cluster defense confrontation. Background Art

[0002] UUVs have good concealment and adaptability to harsh environments. Once a cluster confrontation network is formed in a large area of ​​water in the future, it will bring great challenges to the existing defense system in terms of underwater detection and coordinated attack.

[0003] Although acoustic and other non-acoustic sensing technologies have made great progress, detection accuracy and coverage are still limited in complex and changing marine environments, especially in deep sea areas. Underwater communications mainly rely on sound waves, which leads to high latency and low data transmission rates, affecting the real-time and flexibility of command and control systems. Long-term operation of UUVs requires continuous energy supply. Current technology is difficult to meet the needs of large-scale clusters for long-term operations. In addition, current defense systems are mostly designed based on preset rules and static models. It is difficult to respond quickly to the flexible and changeable tactics of enemy UUV clusters. Due to the long data collection, processing and analysis process, it is difficult for the defender to obtain the latest battlefield situation information in a timely manner.

[0004] Therefore, it is urgent to launch defense and confrontation against the threat of underwater unmanned submersible swarms that may appear in the marine environment and to propose effective defense and confrontation methods for underwater unmanned submersible swarms. Summary of the invention

[0005] In view of this, the present invention provides an underwater unmanned submersible cluster defense confrontation method, which can be used for underwater defense resistance, and can greatly increase the underwater reconnaissance search range, improve the response speed and confrontation effect.

[0006] To achieve the above object, the present invention provides a method for underwater unmanned submersible vehicle cluster defense confrontation, comprising the following steps:

[0007] Heterogeneous underwater equipment with different functions is assembled in a semi-autonomous or fully autonomous manner to initiate collaborative perception actions, collaborative jamming actions, collaborative deception actions, collaborative ambush actions and cluster confrontation actions to conduct defensive confrontation with enemy UUV clusters. Among them, underwater unmanned submersible cluster defense confrontation is considered from two perspectives: passive defense after early warning and active defense in advance detection.

[0008] Among them, the passive defense after early warning is specifically as follows: detect UUV groups in the water and obtain target information; according to the number of enemy UUVs found, dispatch one's own UUV group to fight against them, and seek assistance from large or super-large UUVs and ships if necessary;

[0009] Pre-detection active defense specifically involves establishing an active defense barrier at the boundary of the defense sea area.

[0010] Among them, the specific way to establish an active defense barrier at the border of the defense sea area is: to set up underwater fixed or mobile sensors at the border of the defense sea area to establish a persistent surveillance network for sensitive sea areas, or to send out UUV groups by ourselves to operate near ships or in sensitive sea areas. The UUVs carry detection equipment and build a communication network with the mother ship and underwater platforms to realize the sharing of detection information; when the enemy situation is discovered, on the basis of sharing detection information, the ship command and control system coordinates a variety of interception methods for coordinated interception; our dispatched unmanned system clusters carry out cluster coordinated task allocation, drive away or attack the enemy's unmanned system clusters, and adopt suicide attack methods when necessary; at the same time, the mother ship cooperates to assist the underwater unmanned cluster in interception. If the enemy's UUV group formation can be detected, a strategy of concentrated attack on the central area is adopted.

[0011] The defensive confrontation steps include detection, identification and interception, and the specific process is: (a) detecting the unmanned system cluster; (b) identifying the target as friend or foe and making response decisions; (c) intercepting and attacking the enemy target.

[0012] Among them, the optional detection methods include: sonar detection technology and ocean remote sensing technology represented by microwave remote sensing, infrared remote sensing, optical remote sensing, etc.

[0013] Among them, the interception options include: torpedoes, mines, depth charges, pre-placed weapons, attack UUVs, electronic jamming or electronic deception, deception, and cluster confrontation.

[0014] Among them, the heterogeneous underwater equipment includes: reconnaissance UUV, attack UUV, communication relay UUV, floating or submerged buoy, pre-placed weapons, underwater fixed or mobile sensor networks, underwater fixed charging equipment and underwater gliders.

[0015] Beneficial effects:

[0016] 1. The method of the present invention utilizes underwater unmanned clusters to make up for the lack of functions of a single platform with the advantage of quantity, and aggregates underwater platforms with different functions to form a community that can complete a given task together; it replaces traditional expensive large manned platforms with large numbers, small sizes, and low costs of distributed unmanned platforms, which have the characteristics of high efficiency, low cost, reconfigurability, and the ability to perform multiple tasks. It is used for underwater defense and resistance, and can greatly increase the underwater reconnaissance and search range, improve response speed and confrontation effect.

[0017] 2. In the method of the present invention, by deploying a large number of small UUVs, comprehensive coverage of vast sea areas can be achieved, and the monitoring density and frequency of enemy activities can be improved; small UUVs can penetrate deeper into more complex seabed terrain for detailed detection, making up for blind spots that large platforms cannot reach.

[0018] 3. In the present invention, small UUVs are easy to carry and quickly deployed, and their layout can be quickly adjusted according to battlefield needs. When some UUVs fail or need to be evacuated, other members can immediately fill in the gaps to maintain the overall effectiveness of the cluster.

[0019] 4. The method of the present invention uses a small UUV produced in a standardized manner, which can significantly reduce the cost of a single platform. Unmanned operation reduces the risk of casualties and reduces long-term operating costs.

[0020] 5. In the method of the present invention, different UUVs in the cluster can undertake different types of tasks according to their own characteristics, such as reconnaissance, communication relay, interference with enemy equipment, etc. Through efficient internal communication and coordination mechanisms, multiple UUVs can jointly complete complex tasks, such as coordinated attack or joint defense.

[0021] 6. In the method of the present invention, even if part of the UUVs are damaged, the entire cluster can still maintain basic functions, thereby enhancing the reliability and survivability of the system. The cluster has the ability to self-repair and reconfigure, and can quickly restore combat effectiveness after being attacked. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figure 1 It is a schematic diagram of the process of defending against an enemy UUV cluster in an embodiment of the method of the present invention. DETAILED DESCRIPTION

[0023] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0024] The present invention provides an underwater unmanned submersible vehicle cluster defense confrontation method, comprising the following steps:

[0025] Heterogeneous underwater equipment with different functions is formed in a semi-autonomous or fully autonomous manner to carry out coordinated perception actions, coordinated jamming actions, coordinated deception actions, coordinated ambush actions and cluster confrontation actions, etc., to conduct defensive confrontation with enemy UUV clusters.

[0026] Among them, the underwater unmanned submersible swarm defense confrontation is considered from two perspectives: passive defense after early warning and active defense in advance detection.

[0027] Passive defense after early warning is as follows: Passive defense requires timely detection of threat targets to leave enough time for subsequent interception measures. Detection of UUV groups in the water is mainly based on sonar detection, supplemented by ocean remote sensing technologies represented by microwave remote sensing, infrared remote sensing, and optical remote sensing, to obtain target information in a timely manner. According to the number of enemy UUVs found, dispatch your own UUV group to fight against them, and seek assistance from your own large or super-large UUVs and ships if necessary (such as launching torpedoes to attack the enemy).

[0028] Pre-detection active defense is specifically: to ensure the safety of our side, we adopt active defense strategies and establish active defense barriers at the border of the defense sea area. Underwater fixed or mobile sensors are set up at the border of the defense sea area to establish a persistent surveillance network for sensitive sea areas, or UUV groups are dispatched by our side to operate near ships or in sensitive sea areas. UUVs carry sonar and other detection equipment, and build a communication network with the mother ship and underwater platforms to realize the sharing of detection information. The deployment of reconnaissance UUV clusters will greatly increase the detection range of the defense system and effectively improve the overall defense capability. When the enemy is discovered, the ship command and control system coordinates multiple interception methods for coordinated interception based on the shared detection information. Our dispatched unmanned system clusters carry out cluster coordinated task allocation, drive away or attack the enemy unmanned system clusters, and take suicide attack methods when necessary; at the same time, the mother ship should cooperate, launch torpedoes underwater, etc., to assist the underwater unmanned clusters in interception. If the enemy UUV group formation can be detected, a strategy of concentrated attack on the central area can be adopted. During this process, the command and control system needs to focus on how the aforementioned multiple interception methods share and utilize detection information, and how to allocate tasks for coordinated interception.

[0029] Furthermore, the heterogeneous underwater equipment includes: reconnaissance UUV, attack UUV, communication relay UUV, floating or submerged buoys, pre-placed weapons, large or super-large UUV, underwater fixed or mobile sensor networks, underwater fixed charging equipment and underwater gliders, etc.

[0030] The defensive confrontation steps include detection, identification and interception, and the specific process is: (a) detecting the unmanned system cluster; (b) identifying the target as friend or foe and making response decisions; (c) intercepting and attacking the enemy target.

[0031] Among them, the optional detection methods include: sonar detection technology (the main technical means to detect, classify, locate and track targets to meet the needs of underwater communication and navigation) and marine remote sensing technology represented by microwave remote sensing, infrared remote sensing, optical remote sensing, etc. (supplementary technical means).

[0032] The optional interception methods include: traditional weapons (torpedoes, mines, depth charges), new weapons (pre-positioned weapons, attack UUVs), soft kill methods (electronic jamming or electronic deception, deception) and cluster confrontation (with the ability to coordinate, detect and share detection information, coordinate interception and confrontation, situation assessment and autonomous decision-making).

[0033] The method of the present invention is described by taking a specific UUV arrangement as an example. The UUV arrangement of this embodiment is as follows:

[0034] Determine the marine defense area, define the alert level of different areas, determine the defense confrontation tactical plan according to the confrontation situation and equipment functions, adopt a radial strategic layout centered on the ship command and control system, and adopt an offensive and defensive tactic of active defense as the main and passive defense as the auxiliary. The defense area is divided into three layers. The outermost layer is the reconnaissance layer, where a large number of underwater fixed or mobile sensor networks and reconnaissance UUVs are deployed to conduct persistent monitoring at the border of the defense area. At the same time, pre-positioned weapons and attack UUVs are deployed at fixed points in the border area to form a distributed agile response system to build an active defense barrier; the middle layer deploys reconnaissance UUVs, attack UUVs, and communication relay UUVs to ensure the connection between the inner and outer platforms, and conduct regular inspections to check for enemy targets that have broken through the first line of defense; the innermost layer is large or super-large attack and defense integrated UUVs, which have super-long self-sustaining and endurance, and powerful functions of reconnaissance and attack. They are not only the last powerful firepower line to protect the command center, but also a sharp sword that the command center can send to sneak into the opponent's cluster camp to carry out sneak attacks and breakthroughs.

[0035] According to the tactical plan, underwater fixed charging equipment, fixed or mobile communication nodes, floating or submerged buoys, etc. are deployed in the water or on the seabed to create a good survival and information transmission environment for the UUV cluster and lay the foundation for cluster coordinated confrontation.

[0036] In this embodiment, the process of defending against the enemy UUV cluster is as follows: Figure 1 As shown, the specific steps are as follows:

[0037] 1) Each UUV forms a formation according to the command and performs the planned route reconnaissance mission after taking position;

[0038] 2) The underwater fixed or mobile sensors or reconnaissance UUVs of the first line of defense detect suspicious targets and feed back the target characteristics and location information to the command center. If the command center determines that it is not an enemy target threat, it orders the reconnaissance UUV to execute the expulsion order; if the command center determines that it is an enemy target threat, it makes combat decisions based on the target characteristics and number, and conducts interception and strikes. The strike plans include electronic warfare, pre-positioned weapons, attack UUVs (single or clustered), and multi-functional large or super-large UUVs.

[0039] 3) If a suspicious target breaks through the first line of defense and is detected by the middle-layer reconnaissance UUV, the target characteristics and location information will be fed back to the command center. If the command center determines that it is not an enemy target threat, the reconnaissance UUV will be ordered to execute the expulsion order; if the command center determines that it is an enemy target threat, attack UUVs (single or cluster), multifunctional large or super-large UUVs will be selected for interception based on the target characteristics and quantity, and the activity will be adjusted in real time according to the confrontation situation to intercept enemy targets outside the central layer.

[0040] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
