[0002] Electronic countermeasure is an action that uses professional technologies such as electromagnetism and directed energy to weaken, deceive, and destroy the opponent's electronic spectrum, communication links, electronic devices, and networks, reduce the opponent's electronic countermeasure effectiveness, and protect our electronic devices, systems, and networks from being damaged by the opponent. The sea has become one of the main scenarios for electronic countermeasures due to its vast electromagnetic emission space and strict communication requirements. Moreover, electronic countermeasures can achieve greater mission benefits at a relatively low cost. Therefore, the research on maritime electronic countermeasures is of great significance.

[0003] In modern maritime electronic countermeasure scenarios, it is difficult for a single electronic countermeasure entity to complete electronic countermeasure tasks. The distributed cooperation task mode is an important way to achieve high-demand maritime electronic countermeasure tasks.

In this scenario, our electromagnetic resources include a command mother ship, electromagnetic interference machines, electromagnetic interference unmanned aerial vehicles, electromagnetic interference ships, electromagnetic interference unmanned boats, etc. The mission is to interfere with the opponent's electronic reconnaissance equipment to protect the cruise missile to reach the designated location. Compared with all entities operating alone, the interaction between various nodes can improve the mission efficiency and reduce the difficulty of the task for a single electronic countermeasure entity. However, an important problem faced by distributed maritime electronic countermeasures is how to allocate and manage each electromagnetic node and the electromagnetic resources within the node. Currently, there is no unified distributed electromagnetic resource management framework or system for the maritime scenario. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of the present invention.

[0018] Please refer to Figure 1 , an electromagnetic resource management method for maritime distributed electronic countermeasure, comprising the following steps: S1. Determine the input and output content based on prior relevant knowledge and experience, the goals and purposes of the task, and determine the allocation of each electromagnetic node; S2. Establish a network communication module according to the input and output content, the actual scenario, and electromagnetic assets, and maintain and manage the communication inside the node and between the resource manager and each node; S3. Incorporate the OODA loop into the resource manager to achieve the operation allocation of each electromagnetic node.

[0019] The whole is composed of input and output, a network communication module, and a core resource manager. The resource manager is composed of a task parsing module, a comparison and analysis module, a decision-making analysis module, an execution module, and an evaluation and assessment module.

[0020] In the electronic countermeasure resource management system of this embodiment, the input is the purpose, goal, and prior knowledge. The output includes the allocation operation of the electronic countermeasure electromagnetic nodes. The backbone of the electronic countermeasure resource management system is the network communication module, which is responsible for helping each node transfer information between resource managers. The network communication module can be flexibly designed when the electronic countermeasure system is established and can be modified according to the scenario and electronic countermeasure electromagnetic assets. This module includes a physical layer, a media access control layer, and a network layer to achieve communication. The specific implementation depends on the application and scenario and needs to adapt to the environment. The network layer needs to solve the communication problems inside the node and between the resource manager and each node. The OODA loop highly condenses the modern confrontation process into four links: "observation, judgment, decision-making, and action". This division of the confrontation process has been widely recognized and has been widely applied in various fields. This embodiment incorporates the idea of the OODA loop into the design of the resource manager. The core of the electronic countermeasure resource management system is the resource manager, which is the system core to achieve the allocation from purpose to operation. According to the electronic countermeasure application field, the resource manager is successively composed of a task parsing module, a comparison and analysis module, a decision-making analysis module, an execution module, and an evaluation and assessment module, and each module is connected by the network communication module for communication.

[0021] The network communication module maintains and manages the communication between nodes according to the network allocation of the resource manager. As nodes and resources are temporarily added or removed, capabilities, nodes, and resources become available or are removed, and this module will backfill information to other modules. This backfill provides capabilities for modules such as the decision-making analysis module, enabling it to understand the feasibility of executing a certain waveform or algorithm based on the data reported by the nodes. The network communication module is directly connected to all modules in the resource manager. This ensures the provision and sharing of the latest information among all modules in the resource manager and the situation awareness database. The communication of each module will enable the system to make the most informed decisions when facing a constantly changing physical environment, radio frequency, and threat environment. At the same time, the communication link must be robust and adaptable to the changing environment.

[0022] The resource manager must manage electromagnetic resources according to the situation and available resources to meet mission requirements.

[0023] Mission parsing module: The mission parsing module converts mission goals and objectives into corresponding specific tasks and resource metrics. The mission parsing module is connected to the situation awareness database, observes and collects maritime information through nodes, and polls the database to obtain information such as the maritime environment, node status, our spectrum usage, and active threats, forming a perception and cognition of the external situation. Due to differences in mission requirements, expected results, maritime situation, and node hardware availability, the parsing results of the mission will vary. The main function of this module is to convert human-readable requests into machine-readable formats, provide the resource metrics to be considered in this confrontation, and provide a basis for constructing decision-making solutions for the comparison and analysis module by splitting the requests into comparable objects.

[0024] Comparison and analysis module: It will make judgments based on the tasks and metrics provided by the mission parsing module and generate solution plans. The comparison and analysis module understands the internal methods (available waveforms, algorithms, and functions) of the system through the situation awareness database, so it can compare the available capabilities with the required resources, thereby providing all solution plans that can complete the mission. However, at this time, the comparison and analysis module does not understand the node information in the current network communication. The comparison and analysis module needs to weigh the tasks of the mission parsing module against the internal methods. This implementation method can be a weighted mathematical approach or an intelligent algorithm. The input from the situation awareness database will determine the feasibility of using each potential confrontation plan, and the metrics of the mission parsing module can be used to evaluate the plan effects. The intelligent algorithm refers to: using a lightweight trained deep learning network, reinforcement learning method, or heuristic algorithm for calculation, comparing with the input of the situation awareness database, considering the mission goals and objectives, and the situation, and sorting and outputting the executable plans according to the success probability, complexity, and resource requirements of the potential solution plans. The output of the comparison and analysis module is different solution plans, and the solution plans are arranged according to different resource requirements and possible confrontation effects. This output will be passed to the decision analysis module.

[0025] Decision analysis module: Receives the solution plans generated by the comparison and analysis module and determines the best method based on the available resources. The typical electromagnetic resources of this module include instantaneous bandwidth, processing power, frequency band, energy, power, computing resources, and system memory. In addition, the number and location of jammers or different nodes should also be considered to achieve geospatial advantages. The decision analysis module determines the status, capabilities, and locations of nodes on the network by regularly polling the situation awareness database, thereby tracking the current total resource usage. It clearly understands the information and status of the currently available nodes. Based on the availability and capabilities of the nodes, the decision analysis module decides the best method to achieve the mission goals or objectives, makes decisions, and sends specific commands to the corresponding nodes.

[0026] Execution module: After receiving a decision, it first considers the association logic of each node and executes the specific commands given by the decision analysis module according to the action logic. The execution module includes four main parts: (1) Reception: Responsible for receiving any radio frequency transmission; (2) Transmission: Responsible for transmitting any radio frequency radiation; (3) Processing: Responsible for executing any algorithm or generating the required waveforms; (4) Movement: Responsible for controlling and maintaining the movement of any node.

[0027] The output of the execution module is directly connected to the hardware of the node, which helps with tasks such as determining which waveform to output, which power amplifier and antenna to use, etc.

[0028] The evaluation and assessment module receives the actual confrontation information returned by the node through the network communication module, evaluates the effect of the implemented plan, compares the expected effect with the actual effect, updates the perception and cognition parameters in the situation awareness database, enhances the perception and cognition ability of the situation awareness database in the current situation, makes the situation awareness database more adaptable to the current maritime situation, has a deeper understanding of its own electromagnetic resources, and makes more scientific and practical judgments. At the same time, it also forms a management optimization closed-loop for the system to meet the requirements of confrontation effect assessment.

[0029] Example: Such as Figure 2 , the mission objective of the scenario is to interfere with the target early warning network so that our cruise missiles can attack the target without being detected by the other party. In this scenario, the command mother aircraft has obtained mission information from our airborne early warning and control system (non-page) and is aware of the other party's early warning network. After entering the designated area, the pilot chooses to start disrupting the early warning network. In this case, the command mother aircraft has no anti-radar electronic countermeasure measures and can only rely on one electromagnetic interference aircraft and three electromagnetic interference unmanned aerial vehicles to provide cover for the missile to fly over.

[0030] Previously, the perception and cognition ability of the situation awareness database has been supplemented with the knowledge in the current scenario. The host system (the command mother aircraft in this embodiment) first calls the electronic countermeasure resource management system of this embodiment according to the commander's request. The electronic countermeasure resource management system will poll the situation awareness database to check the status for authorization verification, and then identify the commander's order as: interfering with the other party's electromagnetic network. As Figure 3 shown, it shows the instantiated resource manager for the task of interfering with the other party's electromagnetic network in this instance, showing the instantiated content, input, and output of each module. The network communication module is hidden in the figure, but all data and information need to be transmitted through the network communication module.

[0031] The task analysis module first receives the commander's command to "interfere with the other party's electromagnetic network", calls the node to observe and collect maritime information, perceives and recognizes the maritime situation, integrates the maritime situation to analyze the command, decomposes it into a machine-readable format, and determines the indicators required for the task from the situation awareness database as RAPDT (transmitting and receiving resource consumption, algorithm consumption, transmission power, transmission duty cycle, and effect time). This result is transmitted to the comparison and analysis module through the network communication module.

[0032] The comparative analysis module weighs the machine-readable tasks and indicators with the internally available methods (combined waveforms, algorithms) to make judgments and determine all the combined interference waveforms that can meet the mission objectives. Figure 3 The comparative analysis module shows an intelligent algorithm that takes into account the complexity of generating a given combination of waveforms and running the algorithm, uses previous data to generate a lightweight deep learning network, learns all weighted parameters and outputs parameters for the current situation, and generates combined interference waveforms A, B, C, D, and E that can complete the task. These five waveforms are optional solutions that can solve the commander's purpose. Although all five combined waveforms are available, they will produce different effects, and these five combined waveforms are different, with different requirements for hardware and resources: (1) Combined waveform A (burn-through): It can directly burn the opponent's early warning network. It requires the consumption of R1's transceiver resources, a large amount of processing resources required to execute algorithm A1, and a maximum transmission power P1 with a low transmission duty cycle D1 at frequency F1 and extremely small bandwidth B1. The effective time T1 is 0.

[0033] (2) Combined waveform B (exceeds the interference threshold and has a short duration): It can interfere with the opponent's entire early warning network. It requires R2's transmit and receive resource consumption and medium processing resources to execute algorithm A2, but requires a large transmit power P2 with a medium transmit duty cycle D2 at a frequency of F1 and a bandwidth of B2. The effective duration T2 is short.

[0034] (3) Combined waveform C (reaching the interference threshold, moderate time): It can interfere with the opponent's entire early warning network, requiring R3's transceiver resource consumption and appropriate processing resources to execute algorithm A3, but requires a moderate transmit power P3 with a moderate transmit duty cycle D3 at a frequency of F1 and a bandwidth of B3, and the effect time T3 is moderate.

[0035] (4) Combined waveform D (may not meet the threshold, slightly longer time): may interfere with the opponent's partial early warning network, requiring R4's transmit and receive resource consumption and a small amount of processing resources to execute algorithm A4, but requiring a small transmit power P4 with a high transmit duty cycle D4 of frequency F1 and bandwidth B4, and the effect time T4 is slightly longer.

[0036] (5) Composite waveform E (can only generate shielding area, long duration): It can only generate one shielding area, allowing our side to pass through. It requires the transceiver resources of R5 and a small amount of processing resources for executing algorithm A5. However, it requires a small transmission power P5 with a high transmission duty cycle D5 at a frequency of F1 and a bandwidth of B5, and the effective time T5 is long.

[0037] Figure 4 It shows the resource usage of RAPDT (transceiver resource consumption, algorithm processing, transmission power, transmission duty cycle, and effective time), which can be considered when weighing various resources. Next, the comparison and analysis module compares and analyzes each composite interference waveform with the input and indicators of the situation awareness database, sorts each composite interference waveform, and transmits it to the decision-making analysis module. Since the decision-making analysis module knows the status, capabilities, and locations of the nodes in the network, it will discover four local nodes in the network, namely three electromagnetic interference UAVs and one electromagnetic interference aircraft. By analyzing the available resources, it is found that the system has available resources to execute composite waveforms B, C, D, and E, but does not meet the required resources of composite waveform A. Subsequently, the decision-making analysis module calculates the efficiency of transmitting each composite waveform, and collaboratively considers the situation of each node and the current situation, and believes that in the current situation, composite waveform C is the best solution that can meet the requirements of the commander, and issues a decision to execute composite waveform C. The decision-making analysis module will send the specific action plan to the execution module to implement composite waveform C (i.e., configure sensing, processing, and transmission resources).

[0038] In this embodiment, if the resources required to generate composite waveform C have recently left the network (such as the electromagnetic interference machine is not in the operation area), the network communication module will report this situation to the comparison and analysis module, and then the comparison and analysis module will use this information to weight the tasks differently, which may produce another result.

[0039] Finally, the execution module outputs commands to each node to execute composite waveform C. The target nodes respond, considering the associated logic of each node, turn the antenna to a given area in space (such as an early warning network), tune to frequency F1 to receive radio frequency, process the digital radio frequency (such as data) using algorithm A3, generate composite waveform C using the result, and transmit composite waveform C at power P3 on frequency F1. After that, each target node will report the status and task execution effect to the evaluation and assessment module.

[0040] The evaluation and assessment module receives the feedback of countermeasure information from each node through the network communication module, understands the status of each node, evaluates the countermeasure effect, and returns the effect evaluation of the task to the situation awareness database, enhancing the perception and cognition ability of the situation awareness database, and forming a closed loop of the countermeasure process.

[0041] Therefore, the present invention adopts the above-mentioned electromagnetic resource management method for maritime distributed electronic countermeasures, realizes the transformation from the commander's goal to the actual electromagnetic actions, realizes electromagnetic management and task allocation in maritime distributed electronic countermeasures, and improves the distributed cooperation ability in maritime electronic countermeasure applications.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that they can still modify or equivalently replace the technical solutions of the present invention, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present invention.
