Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of military simulation and training, and particularly relates to a training system for simulating signal combat and a training method thereof. BACKGROUND

[0002] With the accelerated evolution of modern war patterns towards informatization and intelligentization, simulating signal combat training has become a core means to improve the electronic countermeasure capability and battlefield situation awareness level of troops. Traditional training systems mostly rely on pre-set scripts and fixed signal parameters to construct the countermeasure scene, and the underlying logic is based on a static electromagnetic environment model and linear deduction rules, which is difficult to truly restore the dynamic countermeasure behavior of signal jamming, spectrum hopping and multi-source deception in complex battlefield. In a high-intensity electromagnetic countermeasure environment, the signal features of the enemy evolve in real time with the tactical intent and equipment state, while the existing systems lack the ability to adaptively model the signal behavior patterns, often leading to distorted training scenes, insufficient countermeasure intensity, and delayed tactical feedback, making it difficult for trainees to establish a deep understanding of real battlefield signal game. In addition, commanders have increasing needs for post-mortem analysis of the training process, tactical effectiveness evaluation and personalized subject customization. Traditional systems cannot support multi-level, multi-role and multi-round deep countermeasure deduction due to single data dimension, difficulty in behavior tracing and rigid scene reconstruction.

[0003] Among them, the training method for simulating signal combat focuses on constructing countermeasure signal bodies with dynamic evolution ability and interactive tactical decision chains, and the core goal is to realize immersive countermeasure training in the whole process of "detection-judgment-disturbance-evaluation" through high-fidelity signal behavior simulation and closed-loop tactical feedback mechanism. This direction requires the system not only to simulate the emission characteristics and modulation strategies of enemy radar, communication and navigation multi-system signals, but also to adjust the countermeasure intensity and deception mode in real time according to the trainee's operation, forming an intelligent countermeasure entity with tactical intent.

[0004] The existing technology generally has three major defects of single signal behavior modeling dimension, lack of adaptive evolution of countermeasure strategy, and disconnection between training process and tactical evaluation. Most systems can only simulate static signal sources with fixed frequency bands and fixed modulation modes, and cannot dynamically adjust signal parameters and emission strategies according to the battlefield situation; the countermeasure engine mostly adopts rule-driven mode, lacks behavior prediction and intent deduction ability based on machine learning, leading to mechanical repetition of countermeasure behavior and lack of tactical depth; the training data collection is limited to signal transceiver logs, and the closed-loop feedback chain of "operation-response-effectiveness-evaluation" cannot be established, resulting in superficial post-mortem analysis and inability to accurately locate tactical shortfalls. Under the background of joint operations and multi-domain cooperation, the above defects seriously restrict the ability of troops to quickly identify threats, flexibly develop countermeasures and cooperatively implement electronic attack and defense in complex electromagnetic environments, and there is an urgent need to build a simulated signal combat training system with intelligent signal evolution, dynamic countermeasure deduction and deep tactical evaluation capabilities. SUMMARY

[0005] To solve the above technical problems, the present application is proposed. Embodiments of the present application provide a training system for simulating signal operations and a training method thereof, which realizes high-fidelity simulation and adaptive evolution of signal game behavior in a complex battlefield environment by constructing a multi-level dynamic counter-deployment architecture and integrating real-time interaction mechanisms in physical, electromagnetic, and cognitive domains. The system takes a distributed agent cluster as the core carrier, relies on a time-space synchronization engine and a multi-source heterogeneous data fusion hub, establishes a closed-loop training environment covering the whole chain of signal generation, propagation, interference, identification, decision-making, and feedback, enables trainees to hone their signal countermeasures formulation ability, dynamic response ability, and collaborative command ability in a highly realistic virtual battlefield, and thus breaks through the fundamental limitations of traditional static scripted training modes in terms of confrontation reality, strategy diversity, and cognitive depth.

The servo drive mechanism adjusts the spatial azimuth and elevation angles of the reflecting surface in real time according to the reflection path calculated by a ray tracing algorithm, so that the incident signal produces specular reflection and diffuse reflection components in accordance with the principles of geometric optics. The reflection coefficient and polarization characteristics can be dynamically configured according to the material electromagnetic parameter library.

[0017] The wideband digital receiver cluster is used for deployment at key listening locations in a simulated battlefield.

DETAILED DESCRIPTION

[0035] To realize high-fidelity simulation and adaptive evolution of signal game behavior in complex battlefield environment, the present embodiment constructs a training system and a training method for simulating signal combat. The method realizes the three-domain closed-loop interaction mechanism of physical domain, electromagnetic domain and cognitive domain, relies on distributed intelligent agent cluster and multi-source heterogeneous data fusion hub, and establishes a dynamic adversarial deduction architecture covering the whole chain of signal generation, propagation, interference, identification, decision and feedback. The system level is deployed with modular hardware units and standardized software entities, which supports the reproduction of real battlefield electromagnetic environment in laboratory environment, and realizes the systematic training of the trainees' adversarial strategy formulation ability, dynamic response ability and cooperative command ability.

[0036] Please refer to Figure 1 and Figure 2 , the method comprises the following steps: S1, by deploying a distributed radio frequency signal transceiver array in a physical space, a three-dimensional electromagnetic field simulation environment covering a specified geographic area is constructed, wherein each radio frequency unit is configured with an independent frequency modulation module, a power control module and a directional pattern reconfigurable antenna structure, supporting dynamically generating simulated radiation source signals with specific modulation patterns, time domain envelopes and spatial directivity in a specified frequency band.

[0037] In the S1 step, first, according to the training scene requirements, a plurality of radio frequency transmitting and receiving nodes are laid out in a three-dimensional space according to a preset topological structure. Each node includes a radio frequency front-end module, a baseband processing module and a time-space synchronization module. The radio frequency front-end module supports continuous tuning in the three hundred megahertz to six gigahertz frequency band, and the output power dynamic range covers negative thirty to positive thirty dBm, the frequency tuning step precision is ten kilohertz, and the power adjustment resolution is zero point one dBm. The baseband processing module has twelve standard modulation pattern generators built-in, including frequency modulation, phase modulation, and quadrature amplitude modulation, each modulation pattern supports independent configuration of symbol rate, roll-off coefficient and constellation mapping rule. The directional pattern reconfigurable antenna structure is composed of eight element phased arrays, supporting dynamic adjustment of beam pointing in the range of zero to three hundred sixty degrees in azimuth angle and negative ninety to ninety degrees in elevation angle, and the beam main lobe width can be continuously adjusted between five to sixty degrees according to task requirements.

[0038] In the signal generation process, the system allocates independent carrier frequency, transmission power, modulation parameter and spatial pointing angle for each radio frequency unit according to the instructions issued by the central data fusion platform. The baseband processing module generates corresponding baseband I / Q data stream according to the instructions, which is sent to the radio frequency front-end module for up-conversion and power amplification after digital-to-analog conversion. The time-space synchronization module realizes nanosecond-level time alignment of the whole system through Beidou timing signal and fiber time distribution network, ensuring that all radio frequency units transmit signals synchronously under the unified time reference. Each radio frequency unit performs self-checking process before transmission, including power calibration, frequency locking state detection and antenna standing wave ratio measurement, if any parameter exceeds the preset threshold, local alarm is triggered and transmission is suspended, at the same time, the abnormal state code is reported to the central data fusion platform.

[0039] S2, by embedding programmable attenuator array and multipath reflection simulator in the electromagnetic propagation path, according to the preset terrain data and atmospheric refraction model, the atmospheric refraction model includes the following two core parts: 1. Refractive Index Gradient Model This is the key to realize the "refraction effect". The system estimates the refractive index of the atmosphere through real-time collected atmospheric temperature and humidity data; using these data to calculate the gradient of the refractive index with height or space (i.e. ); This gradient is used to correct the propagation path (bending) of electromagnetic waves, thereby affecting: Doppler shift; signal arrival time; reception angle.

[0040] Here is a model of refractive index based on the spatial distribution of temperature, humidity, and air pressure, usually in the form of:

[0041] Where: Absolute temperature (K), Total air pressure (hPa), Water vapor pressure (hhPa).

[0042] This formula is the standard model recommended by the International Telecommunication Union (ITU), also known as the ITU-R P834 model; 2, Atmospheric Absorption Loss Model, the absorption of specific frequency electromagnetic waves by air molecules (such as oxygen O2, water vapor H2O). The absorption intensity is different at different frequencies (for example: 22GHz and 60GHz are strong absorption bands of water vapor) and is related to path length, humidity, and temperature.

[0043] Common models include: ITU-R P.676: Standard Model of Atmospheric Absorption Attenuation; Mie scattering model: suitable for rain and fog particle scattering; Hagmann model: for millimeter wave communication.

[0044] The atmospheric refraction model is actually a comprehensive propagation environment model that not only includes refraction but also absorption.

[0045] Real-time calculation and application of path loss, multipath time delay spread, Doppler shift, and polarization rotation effects make the simulated signal exhibit consistent fading characteristics and spatial dispersion behavior with real battlefield environment during propagation.

[0046] In the S2 step, the system first loads the digital elevation model and land cover type map corresponding to the current training scene, combines real-time collected atmospheric temperature and humidity data to construct a three-dimensional spatial propagation environment parameter field. The propagation model calculation module uses ray tracing algorithm to geometrically model all possible propagation paths of each radio frequency signal from the transmitting point to the receiving point, and calculates the free space loss, diffraction loss, reflection loss, and atmospheric absorption loss of each path. For each path, the system calculates the Doppler shift based on the path length and atmospheric refractive index gradient, and calculates the polarization rotation matrix based on the incident angle and reflection surface material properties.

[0047] A programmable attenuator array is deployed at key nodes of the propagation path, each attenuator unit supports program-controlled adjustment in the range of zero to one hundred and twenty dBm with zero point five dBm steps. The propagation model calculation module decomposes the total loss value of each path into several segments and assigns them to the attenuator units at the corresponding locations, generating a sequence of attenuation control instructions. The instruction sequence contains target attenuation values, adjustment rates, and effective time stamps, which are sent to each attenuator unit through a dedicated control bus. After receiving the instructions, the attenuator unit adjusts the attenuation value at the specified time point and at the specified rate, and confirms the execution status to the propagation model calculation module through the feedback channel.

[0048] The multipath reflection simulator deploys multiple movable reflective surface units in a specified spatial region, each reflective surface unit is composed of a metal mesh structure and a servo drive mechanism. The servo drive mechanism adjusts the spatial azimuth and elevation angles of the reflective surface in real time according to the reflection path calculated by the ray tracing algorithm, so that the incident signal produces specular reflection and diffuse reflection components consistent with the principles of geometric optics. The reflection coefficient and polarization characteristics are dynamically configured based on the material electromagnetic parameter library, supporting electromagnetic response simulation of multiple typical battlefield materials such as copper, aluminum, concrete, and vegetation. The servo drive mechanism has a built-in position closed-loop controller to ensure that the angle adjustment error of the reflective surface is less than zero point one degree, and the angle adjustment response time is less than fifty milliseconds. The system performs collision detection before each angle adjustment, and if the target angle will cause mechanical interference, it automatically selects a suboptimal angle and reports a conflict log.

[0049] S3, by deploying a wideband digital receiver cluster at the receiving end, each receiver integrates a high-speed analog-to-digital converter, a digital down-conversion module, and a real-time spectrum analysis engine, for full-band continuous sampling, channelization processing, and instantaneous spectral feature extraction of the superimposed multi-source signals in space, and synchronously uploading the original time-domain waveform data and frequency-domain feature vectors to the central data fusion platform.

[0050] In the S3 step, the wideband digital receiver cluster is deployed at key listening locations in the simulated battlefield, each receiver contains a twelve-bit analog-to-digital converter with a sampling rate of five gigahertz, a digital down-conversion channel supporting a real-time bandwidth of two hundred megahertz, and a spectrum analysis unit based on fast Fourier transform. The receiver antenna receives the superimposed multi-source radio frequency signals in space, which are sent to the analog-to-digital converter for digital sampling after low-noise amplification and anti-aliasing filtering. The sampled data stream enters the digital down-conversion module, which performs digital mixing and decimation filtering according to the pre-set center frequency and bandwidth parameters, and outputs the baseband I / Q data stream.

[0051] The real-time spectrum analysis engine processes the baseband I / Q data stream in segments, each segment being 8,192 points long, and performs a fast Fourier transform after windowing with a Hanning window function to obtain the frequency domain amplitude spectrum and phase spectrum. The spectrum analysis engine further extracts the instantaneous spectral feature vector, including the spectral centroid, spectral entropy, peak frequency, bandwidth occupancy rate, and modulation recognition features. The original time domain waveform data and frequency domain feature vector are uploaded in real time to the central data fusion platform through a gigabit Ethernet interface, and the data format complies with a unified timestamp marking and channel identification protocol. Each data packet contains a sampling start timestamp, a receiver identifier, a center frequency, a bandwidth parameter, an original I / Q data block, and a feature vector array. The receiver has a built-in data buffering mechanism that can temporarily store up to ten seconds of data when the network is congested, and when the network recovers, the data is transmitted in time sequence to ensure data integrity.

[0052] S4, by constructing an intelligent adversarial agent cluster based on a deep reinforcement learning framework, each agent is configured with an independent state perception module, a policy generation module, and an action execution module. The state perception module receives multi-dimensional battlefield situation information from the central data fusion platform, including enemy and friendly signal source positions, spectrum occupation maps, interference intensity distribution, and communication link quality indicators. The policy generation module outputs the optimal signal transmission parameter adjustment instructions, interference strategy selection instructions, or evasion maneuver instructions based on the current situation and historical interaction experience. The action execution module converts the instructions into specific radio frequency control signals and issues them to the corresponding physical devices for execution.

[0053] In the S4 step, the intelligent adversarial agent cluster deploys multiple software entities with autonomous decision-making capabilities in the virtual command hierarchy, and each agent entity runs in an independent computing container. The state perception module subscribes to battlefield situation updates published by the central data fusion platform through a message queue. The situation information includes enemy signal source three-dimensional coordinates, spectrum occupation heat maps, interference signal intensity spatial distribution maps, own communication link signal-to-noise ratio time series curves, and resource occupation state tables. The state perception module preprocesses the original situation data, including coordinate system conversion, data normalization, and feature splicing, to generate a uniform dimension state vector input to the policy generation module.

[0054] The policy generation module adopts a deep deterministic policy gradient algorithm to construct an action value function, and a neural network structure thereof includes three fully connected layers, each layer having 512, 256 and 128 neurons respectively, and a rectified linear unit as an activation function. The network input is a current state vector, and the output is a continuous action vector including a carrier frequency adjustment amount, a transmission power adjustment amount, a beam pointing angle adjustment amount, a modulation pattern index and an interference strategy identifier. The policy generation module performs forward inference in each decision cycle to generate an optimal action vector, and adds random disturbance according to an exploration noise mechanism to maintain policy diversity. The training of the action value function adopts an experience replay mechanism, randomly samples batches from historical interaction data for gradient descent update, and the initial learning rate is 0.0001, which is attenuated by 10% every 100,000 steps.

[0055] The action execution module converts the action vector into specific radio frequency control signals, and sends parameter adjustment instructions to the physical device control layer through a remote procedure call interface. The instruction content includes a target device identifier, a parameter type, a target value and an effective timestamp. The action execution module starts a heartbeat packet mechanism after sending the instruction, sends a state query request to the target device every 10 milliseconds, and if no confirmation response is received for three consecutive times, it is determined that the instruction execution fails, triggering a local retry mechanism and reporting an abnormal event. The policy generation module updates the internal state according to the instruction execution result, records a positive reward if the instruction execution is successful, and records a negative reward and adjusts the subsequent policy generation weight if the execution fails.

[0056] S5, by establishing a cross-domain collaborative decision-making hub, the hub receives local decision proposals from all intelligent counter-agent, according to the preset command level structure and collaboration rule base, conflict resolution, resource allocation and global strategy optimization, finally generate unified combat instruction sequence and synchronous distribution to each execution unit, ensure that the multi-agent system in complex counter-environment maintain tactical consistency and strategic synergy.

[0057] In the S5 step, the cross-domain collaborative decision-making hub deploys a global strategy coordinator at the top layer of the system architecture, which includes a conflict detection module, a resource arbitration module and an instruction synthesis module. The conflict detection module performs spatiotemporal overlap analysis and target consistency verification based on the decision proposals submitted by each agent. The spatiotemporal overlap analysis calculates the intersection of the spectrum resources, spatial regions and time windows involved in each proposal, and if there is a resource conflict, it is marked as a conflict proposal. The target consistency verification evaluates the contribution of each proposal to the global target according to the preset tactical target priority table, and if the proposal target deviates from the global target by more than a threshold, it is marked as an invalid proposal.

[0058] The resource arbitration module allocates spectrum, power and spatial direction resources to the agents according to a preset priority rule and a resource occupation state table. The priority rule includes three dimensions of task urgency, agent command level and historical contribution, and each dimension is assigned a different weight coefficient. The resource occupation state table records the allocation state and release time of all resources in real time. The resource arbitration module uses a greedy algorithm to allocate the optimal available resource to each conflicting proposal, ensuring maximum resource utilization. For proposals that cannot be allocated resources, the resource arbitration module generates a resource request queue, and reallocates resources in priority order after the resources are released.

[0059] The instruction synthesis module encapsulates the arbitration results into standardized instruction messages. The message format includes instruction type, target agent identifier, parameter list, effective timestamp and check code. The instruction synthesis module distributes the instruction messages to each execution unit through a reliable multicast protocol.
