Description
Technical Field
[0001] The present invention relates to the field of military communication and simulation technology, in particular to a simulation method and system for intelligent fusion and dynamic prediction of electronic warfare intelligence. Background Art
[0002] Current electronic warfare intelligence processing faces core challenges such as low efficiency in multi-source heterogeneous data fusion, poor adaptability to dynamic environments, and insufficient real-time threat prediction. Traditional methods usually adopt static weight allocation strategies in multi-domain sensor data fusion, which makes it difficult to cope with the dynamic changes of signals in complex electromagnetic environments. For example, conventional K-means clustering algorithms are susceptible to noise interference when processing high-dimensional electromagnetic signal features, resulting in reduced sorting accuracy, and lack the ability to quickly adapt to new signal patterns. In addition, existing dynamic prediction models are mostly based on single-modal data, such as radar pulses or communication protocols, and do not fully explore the synergistic correlation of time-domain and spatial-domain features, resulting in limited comprehensiveness and accuracy of battlefield situation awareness.
[0003] In terms of technological evolution, artificial intelligence technology has been gradually applied to the field of electronic warfare in recent years. For example, the U.S. military has achieved rapid identification of unknown radar signals and generation of jamming strategies through cognitive electronic warfare systems such as F-16 / CADS, but its algorithm relies on a fixed rule base and is difficult to adapt to rapidly evolving modulation types and signal distributions.
[0004] Although multimodal knowledge graph technology has made progress in civilian fields such as semantic search tasks, it lacks the ability to model the dynamic association between radar signal features and geospatial information in military scenarios. In addition, existing incremental learning frameworks mostly use global parameter updates, which can easily lead to catastrophic forgetting problems when the model adapts to new signals.

[0041] The purpose of the present invention is to provide a simulation method and system for intelligent fusion and dynamic prediction of electronic warfare intelligence, aiming to improve battlefield survivability and intelligent decision-making support.
[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0043] Reference Figure 1 , showing a simulation method for intelligent fusion and dynamic prediction of electronic warfare intelligence according to an embodiment of the present application, the simulation method comprising: Electromagnetic signal data is collected in real time through multi-domain distributed sensor nodes, and the dynamic adversarial network DAN is used to perform spectrum fingerprint matching and anomaly positioning on the electromagnetic signal data. The spatiotemporal consistency verification mechanism is combined to eliminate invalid data and generate a standardized intelligence stream.
[0044] Specifically, sensor nodes distributed in multiple domains of land, sea and air are deployed, such as airborne radars and shipborne communication detectors, to collect raw electromagnetic signal data in real time. In the dynamic adversarial network DAN, an improved spectral clustering algorithm is used and a quantum annealing optimization mechanism is introduced to perform feature sorting on the electromagnetic signal data. The feature dimensions include carrier frequency, pulse width, and modulation type. The mixed electromagnetic signals are separated into different groups according to carrier frequency, pulse width, and modulation type. The output results of feature sorting are used as the input of the spectrum fingerprint matching. By dynamically updating the cluster center vector and comparing the similarity with the radiation source features in the fingerprint library, abnormal signals are identified and standardized intelligence streams are generated; the loss of the spectrum fingerprint matching is designed as:
[0045] in, is the three-dimensional feature vector of the electromagnetic signal sample, For the The cluster center vector at the iteration, N is the total number of valid signal samples participating in the cluster center update in the current iteration, is the quantum tunneling intensity coefficient, which is 0.8; is the adaptive cutoff threshold, To maximize the difference between classes Minimizing intra-class variance The comprehensive measure of is the quantum confinement factor, Controlling the influence of quantum tunneling effect on feature sorting, smaller It can suppress excessive jumps of quantum bits and balance global exploration and local convergence in complex electromagnetic environments.
[0046] Among them, two core functions are realized simultaneously through the improved spectral clustering algorithm and quantum annealing optimization mechanism. The first is feature sorting, which is to separate the mixed electromagnetic signals into different groups according to carrier frequency, pulse width and modulation type; the second is spectrum fingerprint matching: through the loss function design, the sorting results are dynamically matched with the preset fingerprint library, and the matching accuracy is optimized.
[0047] Cluster center movement The formula for state update is:
[0048] in, is the learning rate, the value is 0.002; Gaussian kernel bandwidth The specific adjustments are:
[0049] in, is the distribution shift sensitivity coefficient, KL divergence is the measure of signal distribution change, For the At iteration The joint probability distribution of For the The cluster center vector at the iteration.
[0050] In the test experiment, the quantum confinement factor was introduced in the carrier frequency dimension = 0.1, by adaptive cutoff threshold =0.05 dynamically eliminates noise interference, which improves the signal sorting accuracy by 12% compared with traditional methods. In the spatiotemporal consistency verification mechanism, by checking the physical constraint relationship between the pulse arrival time difference and the geographic coordinates, the signal propagation speed error is set to ≤5% to eliminate invalid data.
[0051] The output result of the feature sorting is used as the input of the spectrum fingerprint matching. By dynamically updating the cluster center vector and comparing the similarity with the radiation source features in the fingerprint library, abnormal signals are identified and a standardized intelligence stream is generated. Specifically, the sorted signal group is matched with the preset radiation source fingerprint library for similarity, and the matching confidence is calculated based on the dynamically updated cluster center vector. When the confidence is lower than the preset threshold, it is determined to be an abnormal signal and an alarm is triggered.
[0052] Based on the quantum annealing optimization mechanism, the Hamiltonian is introduced to constrain the signal sorting by the pulse width modulation type constraint Hamiltonian, so as to suppress the interference of carrier frequency drift and pulse width jitter on signal sorting. Combining the carrier frequency cluster center constraint and the pulse width distribution prior knowledge, its expression is:
[0053] in, and are the qubit index and the total number of qubits, respectively. and The preferred values of the constraint coefficients of carrier frequency and pulse width are 0.1 and 0.08 respectively; and Respectively The carrier frequency value of quantum bits and the target carrier frequency value, is the reference pulse width distribution, For the The Pauli-Z operator for 1 qubit.
[0054] In the actual experiment, the reference distribution Set it as Gaussian distribution, specifically μ=1.2μs, σ=0.3μs, and KL divergence penalty to make the pulse width estimation mean square error MSE from 0.15μs 2 Down to 0.07μs 2 The signal clustering purity of the same modulation type is increased from 82% to 95%, the false correlation rate is less than 3%, the number of quantum annealing iterations is reduced to 1 / 3 of the traditional method, and the single-task energy consumption is reduced by 58%.
[0055] Figure 2 The framework of the dynamic adversarial network (DAN) is shown. The model structure is designed around the spectrum fingerprint matching and anomaly location requirements of electromagnetic signal processing. It combines multimodal feature fusion and adversarial training mechanisms to build an end-to-end dynamic adaptive network. The model takes the original electromagnetic signal as input. First, the time domain signal is converted into a time-frequency domain spectrum through the short-time Fourier transform (STFT) preprocessing module to achieve the time-frequency joint representation of signal features. The parameter settings of window length 256 and overlap rate 75% can balance time accuracy and frequency resolution. In the shared encoder, the preprocessed spectrum is input to the shared encoder that combines multi-scale convolution and multi-head attention: the multi-scale convolution block uses different kernel sizes such as 3×3, 5×5, and 7×7 to extract local frequency band features in parallel, including the instantaneous frequency point features of radar pulses; the Transformer encoding layer captures the global correlation across frequency bands through the multi-head self-attention mechanism, including focusing on the carrier mutation area of the frequency hopping communication signal to suppress noise interference. In the multi-task collaborative branch, the encoded features are diverted to two parallel task branches: the first branch is the spectrum fingerprint matching branch, which compares the known signal templates based on the dynamically updated memory library, including the radar radiation source fingerprint library, and calculates the cosine similarity between the input signal and the template through the dynamic prototype alignment loss. The threshold ≥0.9 is considered a match; the signal type / ID and matching probability are output to support high-precision recognition in small sample scenarios; the second branch is the anomaly positioning branch, which uses the U-Net decoder to upsample the encoded features and restore the spatial resolution in the time-frequency domain; generates a pixel-level anomaly heat map, including pulse loss or frequency deviation abnormal areas, and combines the binary mask to output the abnormal frequency band and timestamp coordinates, with a positioning error of ≤0.5ms / 2MHz. In the adversarial training optimization, the gradient reversal layer GRL reverses the gradient sign of the feature extractor, forcing the encoder to generate robust features that are independent of the interference environment; the multi-domain discriminator designs independent classification heads for different electromagnetic interference scenarios, including strong noise and multipath effects, and dynamically adjusts the adversarial loss weights. The initial weight λ=0.3 increases to 1.2 with training to achieve cross-domain adaptation. The final output layer integrates the results of the two branches, including fingerprint matching results: identifying signal types in the form of classification probability, including radar model LFM / FSK; anomaly positioning mask: binary thermal images mark abnormal areas, support real-time threat warning in electronic warfare, and the measured end-to-end delay is ≤50ms.
[0056] In the dynamic adversarial network DAN, the robustness of carrier frequency and pulse width characteristics is jointly optimized to improve the defense capability against adversarial samples.
[0057] Define carrier frequency-pulse width joint robustness loss in the adversarial defense module :
[0058] in, To find the expectation of the statistical distribution of the input signal x, ensure that the robustness loss covers all possible signal scenarios; and are the disturbances for carrier frequency f and pulse width pw, respectively. and is the maximum allowable boundary for counteracting disturbances, which are the disturbance amplitudes that limit the carrier frequency and pulse width, respectively. =0.1GHz, =5μs; To measure the distribution difference between the electromagnetic signal data x and the adversarial sample x+δ in the feature space f(.), is the modulation type classification loss weight, which is 0.3 after tuning; is the cross entropy loss, which quantifies the electromagnetic signal data x and the adversarial sample x adv The difference in the modulation type prediction distribution m(.), is a feature extraction function that maps the input signal x to a high-dimensional feature space. is a modulation type classifier that outputs the modulation type probability distribution of the signal x.
[0059] A multimodal knowledge graph is constructed, radar signal features are defined as entities, communication protocol metadata as relationships between entities, and geospatial information as entity attributes. Semantic association modeling is performed and a heterogeneous network representation is generated.
[0060] Specifically, in the construction of the multimodal knowledge graph, a multidimensional feature tensor fusion mechanism is added to define the correlation function between the radar signal modulation type and the protocol metadata. for:
[0061] in, is the total number of modulation types, is the modulation type encoding matrix, which converts the discrete modulation type Mapped to a three-dimensional vector, For the Standard carrier frequency mean value of the modulated signal, used to dynamically adjust the carrier frequency The weight of For tensor product operation, fusion carrier frequency , Pulse Width and time difference ; is a parameter matrix used to adjust the pulse width and time difference The concatenated vector [ ; ] to perform feature mapping; The geographic space information is encoded by using a spherical harmonic function :
[0062] in, is the geographic spatial weight coefficient, is the spherical harmonic basis function, The latitude and longitude coordinates of the signal sources respectively; , , angular quantum number, magnetic quantum number and maximum harmonic order respectively.
[0063] The tensor representation generated by the association function is used as the relationship vector between entities in the knowledge graph, and the spherical harmonic coding result is used as the entity attribute, together forming a heterogeneous network representation containing topological connections and semantic constraints. Specifically, the association function is used to define the dynamic coordination rules between radar signals and communication protocols and generate interpretable semantic relationships; while the spherical harmonic coding is used to achieve high-precision modeling of geographic spatial attributes and embedding of signal propagation characteristics.
[0064] For example, radar signal entity: {ID: RS001, type: linear frequency modulation, carrier frequency: 9.5GHz, pulse width: 1.2μs}; communication protocol entity: {ID: CP002, type: Link-16, encryption level: AES-256, rate: 1Mbps}; geographic entity: {ID: G003, longitude: 116.4°, latitude: 39.9°, signal strength: -80dBm}. The cross-domain entity relationship is mined through the knowledge reasoning engine. For example, when a radar signal group in a certain area, whose carrier frequency is 9.5GHz±0.2GHz, and abnormal communication protocol metadata, such as an unknown encryption algorithm, appear at the same time, a potential electronic warfare attack alarm is triggered. In the experiment, The three-dimensional vector mapping can characterize the signal time-frequency-modulation characteristics. The BPSK mapping is [0.2, 0.7, -0.1], and the QPSK mapping is [0.5, -0.3, 0.8]. Regarding the parameter matrix W, Xavier initialization is used, and the dimension is 2×d, where d is the concatenated vector dimension. In the test, the feature mapping effect is optimal when d=128; when L=6, the average positioning error is 0.48°. When the order is greater than 6, the positioning error decreases slowly, and the amount of calculation increases exponentially. When L=6, the error is 0.82°, which is 41% higher than when L=3.
[0065] A spatiotemporal dual-channel attention mechanism is adopted to fuse the time domain characteristics of the radar pulse sequence and the spatial distribution characteristics of the communication signal group to generate a joint semantic vector; the fusion of multi-source heterogeneous data is achieved through a confidence dynamic allocation algorithm.
[0066] In the spatiotemporal dual-channel attention mechanism, the temporal channel Introduce the carrier frequency-pulse width coupled convolution kernel:
[0067] in, is the carrier frequency difference sensitivity coefficient, and its value is 0.15; is the time domain sliding window length, and are the tth moment and the history The carrier frequency value at the time, For History The pulse width value at the moment, is a function for extracting the periodic characteristics of pulse width; The spatial channel uses pulse width weighted geodesic distance :
[0068] in, is the pulse width difference penalty factor, the value is 0.6; are the feature vectors of nodes i and j respectively, is the eigenvector angle; The dynamic confidence allocation algorithm defines the modulation type entropy weight as follows:
[0069] in, For the The information entropy of the signal modulation type, C is the total number of signal categories, Is the loop variable.
[0070] The time domain features extracted by the carrier frequency-pulse width coupling convolution kernel and the spatial domain features of the pulse width weighted geodesic distance modeling are dynamically fused through the modulation type entropy weight to generate a joint semantic vector, which is input into the spatiotemporal Transformer model for threat prediction.
[0071] For example, in the spatiotemporal dual-channel attention mechanism, the carrier frequency-pulse width coupling convolution kernel w=5 is used in the time domain channel to capture the carrier frequency hopping sequence, and the frequency hopping interval of the frequency-agile radar is ≤1ms; the spatial channel quantifies the signal group distribution density through the pulse width weighted geodesic distance α=0.3, ≥50 pulses per square kilometer. The confidence dynamic allocation algorithm assigns differentiated weights to heterogeneous data according to the entropy weight of the modulation type, such as ω=0.8 for conventional communication signals and ω=1.2 for frequency hopping signals. Simulation tests show that this mechanism increases the distinction between communication interference signals and real threats by 2.7 times.
[0072] Based on the joint semantic vector, the spatiotemporal Transformer model is used to dynamically predict the threat evolution trend, and the multi-task prediction results of threat level, target type and behavioral intention are output; combined with the mixed density network, a dynamic battlefield situation panorama is generated.
[0073] Specifically, in the spatiotemporal Transformer model, a carrier frequency change rate gating mechanism is embedded in the threat prediction module. :
[0074] in, is the carrier frequency change rate, It is the pulse width stability index; The conditional probability distribution of the mixture density network Modeled as:

Beta distribution describes the statistical characteristics of pulse width. and are the shape parameters that control the left-biased and right-biased characteristics of the pulse width distribution, and the Cat distribution represents the probability of modulation type classification. is the modulation type probability vector.
[0076] The carrier frequency change rate gating mechanism dynamically adjusts the attention weight distribution of each time step in the spatiotemporal Transformer model based on the generated joint semantic vector, wherein the attention weight of the historical pulse width feature is enhanced when the carrier frequency change rate exceeds a threshold; the conditional probability distribution modeling of the mixed density network integrates the geographic space coding features with the signal carrier frequency-pulse width joint distribution to generate a dynamic battlefield situation panorama including the threat thermal field and the signal propagation path. For example, In order to control the contribution weight of the carrier frequency change rate to threat prediction, the Sigmoid function output range is [0,1]. =0.8 indicates a high level of concern about carrier frequency mutations; is a linear transformation matrix that maps the input features to the gated space, with a dimension of 128×64, 64 input features, 128 hidden layers, and Xavier initialization; is the carrier frequency change per unit time, the frequency-agile radar signal =0.5 MHz / ms; is the statistical stability of the pulse width sequence, calculated as the inverse of the standard deviation of the pulse width within a sliding window, length r, stable radar pulse σ = 0.1μs → Stability = 8.0; is the mixed weight of the kth Gaussian component, generated by Softmax. When K=3, π=[0.6, 0.3, 0.1], indicating that the main threat comes from category 1; is the carrier frequency center value of the kth Gaussian component, S-band radar μ1=3.0GHz, X-band μ2=9.5GHz; is the discrete degree of carrier frequency distribution, σ=50MHz for conventional radar and σ=200MHz for frequency hopping radar; To control the left / right deviation of pulse width distribution, when κ>λ, it is left-biased. Specifically, short pulse width is concentrated, regular pulse κ=2.0, λ=5.0 (right deviation); burst pulse κ=5.0, λ=2.0 (left deviation); is the probability distribution of modulation type, such as the confidence of [BPSK, QPSK, LFM], p=[0.7, 0.2, 0.1] means the probability of BPSK is 70%.

[0077] Deploy an online incremental learning framework to detect new signal patterns and fine-tune model parameters in layers, giving priority to updating the prediction head module to adapt to the dynamic battlefield environment.
[0078] Among them, the prediction head module is a built-in component of the online incremental learning framework, and its update logic, parameter adjustment, and function execution all rely on the framework's detection and scheduling mechanism. This design ensures the model's ability to quickly adapt to dynamic battlefield environments, while balancing stability and flexibility through a hierarchical update strategy.
[0079] Specifically, in the online incremental learning framework, the detection of the new signal adopts a modulation type entropy change trigger mechanism Specifically:
[0080] When the modulation type distribution entropy value of the new signal batch and historical distribution entropy The difference exceeds the threshold When , the update mechanism of the incremental learning model is triggered; Layered fine-tuning applies quantum noise perturbation to the carrier frequency characteristic layer, specifically:
[0081] in, is the weight matrix of the frequency feature layer, is the average deviation of the signal carrier frequency, is the quantum noise perturbation intensity coefficient.
[0082] For example, the modulation type entropy value The value range is 0~log2(C), where C is the total number of modulation types. For example, when C=5, the maximum entropy is ≈2.32; the modulation type entropy change trigger threshold =0.2, it can effectively capture significant changes in the modulation type distribution, such as the low probability of intercept signal of the newly emerging LPI radar, while avoiding false triggering caused by noise. =1.0, corresponding to BPSK / QPSK mixed mode; new batch entropy value , added LFM signal, difference Δ=0.4> =0.2→trigger update. Quantum noise perturbation intensity coefficient =0.5, the noise disturbance amplitude is about 5% of the weight. In the X-band radar signal, the carrier frequency is 9.5GHz, and the frequency deviation interference of ±0.5MHz can be tolerated. The initial weight of the carrier frequency feature layer is =[0.8, -0.3, 1.2]; after adding noise, it is updated to =[0.8+0.05·N(0,1), -0.3+0.05·N(0,1), 1.2+0.05·N(0,1)]; learning rate =0.005, the model can adapt to new signals, such as FHSS frequency hopping signals, within 10 iterations, and the convergence speed is increased by 40%, and the average carrier frequency offset is =2.5MHz→ =0.92; Weight update amount: ΔW=0.005×N(0,0.05²)×0.92≈±0.0023; =3.0MHz, Sigmoid(3.0)=0.95, the noise disturbance weight is increased to 95%; the enemy radar carrier frequency jumps from 9.5GHz to 9.503GHz→ =3.0MHz → trigger high sensitivity update.
[0083] A reinforcement learning-driven multi-path distribution mechanism is implemented through the edge-cloud collaborative architecture, and the intelligence push priority is dynamically optimized based on the channel state matrix and node security assessment to ensure low-latency transmission of key threat intelligence.
[0084] Specifically, in the edge-cloud collaborative architecture, the multipath distribution mechanism is used to define the carrier frequency-bit error rate joint reward function
[0085] in, , , is the weighting coefficient, The carrier frequency f corresponds to the inverse of the channel bit error rate, is the total transmission time of the signal from the transmitter to the receiver, is the delay sensitivity factor, Security evaluation vector for the node.
[0086] For example, in a conventional tactical communication scenario: =0.3 represents the bit error rate weight, and the tolerance BER≤e -4 , avoid frequent channel switching affecting timeliness; =0.5 represents the delay weight, emphasizing low-latency transmission and requiring end-to-end delay ≤50ms; =0.2 represents the security weight, and the tolerance for node security assessment differences is high. ≤0.3; =50ms, when the delay exceeds 50ms, the reward value decays rapidly; =e 4 , =40ms, =[0.8, 0.9]. In the critical threat intelligence transmission scenario, =0.2 represents the bit error rate weight, requiring the channel bit error rate to be extremely low BER≤e -6 , select high-quality links; =0.3 represents the delay weight, which allows a slightly higher delay and requires the end-to-end delay to be ≤80ms, but requires stable transmission; =0.5 represents the safety weight, strictly limiting the safety difference, ≤0.1; =100ms, the delay penalty decays slowly, avoiding excessive sacrifice of stability; =e 6 , =70ms, =[1.0, 1.0]. In the emergency scenario of strong interference environment, =0.4 represents the bit error rate weight, giving priority to anti-interference links (such as spread spectrum communication, BER≤e -3 ; =0.4 represents the delay weight, requiring the delay to be ≤100ms to support fast response; =0.2 represents the safety weight, temporarily relaxing safety requirements, such as enabling emergency communication protocols; =30ms, =e 3 , =90ms, =[0.6, 0.7], indicating a temporarily enabled emergency node with a degraded safety level but available.
