In this study, radar cross section of electrically large target partly coated with radar absorbing materials has been simulated and analyzed by using shooting and bouncing ray method. First, the simulation results are validated by comparing with multilevel fast multipole method for electrically small objects. Then the radar cross section of electrically large target is calculated and evaluated in three conditions: perfect electric conductor, partly coated and fully coated. The results indicate that part coating plays an equivalent role in a certain range of angles compared with the full coating, which provides a way to reduce cost of coated stealth plane.

Time-series data typically contain issues such as missing data and noise, which can impact the model's precision and stability. This paper proposes a Transformer structure-based visual information-guided temporal data modeling algorithm to address the issues as mentioned above. The algorithm effectively captures the time-series structure of the time-series data, thereby enhancing the model's precision and stability. To evaluate the performance of the proposed algorithm, a dataset containing visual information aligned with time-series data is compiled, and a comprehensive quantitative and qualitative analysis is performed. Conduct a comprehensive quantitative and qualitative analysis. The results indicate that visual information can assist time-series data in capturing the intricate dynamics of the time-series data, thereby enhancing the performance of the proposed algorithm and facilitating its comprehension. The results indicate that visual information can assist time-series data in capturing the complex dynamics of time-series data, and thus in comprehending and predicting their behavior and trends. The application of this algorithm will advance research in the field of modeling and predicting time series data. Applying this algorithm will advance research and practice in modeling and forecasting time series data. © 2023 IEEE.

Deep neural networks for classification are one of the most fundamental topics in machine learning. However, the widely used softmax decision layer, originating from the conventional softmax regression for multi-class classification, fails to guide the powerful feature extractor to explore the topological structure hidden in data, which limits the quality of produced representations. Therefore, we propose a flexible manifold layer for better representation learning in this paper, rather than adding some regularized losses to introduce extra mechanisms. The flexible manifold layer is inspired by SVM which maximizes the geometric margin and usually achieves better results than softmax regression. Since the potential structure is captured due to the explicit guidance of the proposed flexible manifold layer, the noise can be easily detected and filtered out via a designed automatic mechanism. In addition to passing the topological knowledge by latent representations, a knowledge distillation from the manifold layer and decision layer is developed. Extensive experiments show that the proposed model has achieved excellent performance. The code is available at https://***/jzh9830/DeepSVM. © 2023 IEEE.

Aiming at the urgent demand for accurate recognition of ground target by the new-generation of laser proximity fuze, an exploration study on ground target recognition using KNN algorithm based on the echo of the mission-target encounter of laser fuze is conducted. Firstly, the echo equation of mission-target encounter is established by the radar equation. Secondly, the echo data is processed by normalization, and the data is divided into the training dataset and the test dataset. Then, the data are subjected to feature extraction, such as the number of strong scattering points, equivalent target size. Finally, the obtained feature subset is used for target recognition training and testing based on KNN algorithm, linear support vector machine algorithm and Gaussian naive bayes algorithm. The experimental results indicate that the recognition method based on the KNN neighbor algorithm has high accuracy and can effectively achieve classification and recognition of different targets. It has a good application value in the recognition of lase ground fuze, and lays a solid foundation for the subsequent fine recognition and efficient destruction of laser fuze.

To address the need for evaluating the adaptability of radio proximity fuze components under complex conditions, a data-driven modeling method based on target characteristics for assessing fuze echo adaptability to ground backgrounds is proposed. The study investigates the impact of soil moisture content on fuze echo responses, using silty soil as an example. The variation in scattering coefficients of silty soil with different moisture levels and grazing angles is provided. The results show that the scattering coefficient is significantly affected by soil moisture content. For instance, at a grazing angle of 90° and moisture content of 1%, the scattering coefficient is about -8 dB, while at 40% moisture content, the scattering coefficient increases to 3 dB. Using the developed fuze ground background adaptability evaluation model, the echo response characteristics of Ka-band fuzes under different moisture levels were predicted. The results indicate that higher moisture content leads to a higher signal-to-noise ratio in fuze echoes.

Conformal antenna has the characteristics of miniaturization, low profile and large aperture, which is one of the key antenna development trends in the future. How to realize the conformal printing of antennas has been a tricky problem. We propose a high-precision microdroplet jet printing method of conformal antenna, which realizes direct conformal antenna direct printing on curved surfaces. By theoretically deriving the directional map function of an arbitrary directed array, a conical conformal antenna model is established, and the directional map function of the conformal antenna array is obtained. The test results show that the strategy can accurately print a conformal antenna on a curved surface, and the antenna's operating frequency is basically the same as that of the design, with a small return loss, which can satisfy the performance and usage requirements, and it can provide a technical basis for the subsequent design and processing of conformal antennas.

To address the poor adaptability of guided suppression fuzes in jungle backgrounds and enhance radio fuzes' target detection, identification, and anti-jamming capabilities, a study was conducted on the impact of jungle background on fuze burst point control accuracy. Based on the measured data of the backward scattering characteristics of the jungle collected by the fuze, the distribution characteristics of fuze burst points under different wavebands and pitch angles in the jungle background were obtained. The study analyzed the effects of the jungle environment on the fuze's distance-setting accuracy. The findings indicate a strong correlation between the distribution of burst points and the electromagnetic scattering characteristics of the jungle. The dispersion of burst points follows a Gaussian distribution. At a test distance of 30 m, with fuze wavebands in the K, Ka, and V bands and HH polarization, and pitch angles between 30° and 60°, the impact of the jungle background on burst point deviation is within the range of $\pm \mathbf{5} \mathbf{m}$ . The distance distribution of the fuze is 33.5-34.5 m on asphalt surfaces, while it significantly increases to 32–41 m in jungle backgrounds, with a dispersion increase rate of 77%.

Aiming to address the issue of wireless power and data transmission in closed conical metal shell, the ultrasonic transducer is introduced into the system. The system for ultrasonic transmission is constructed with a pair of radially polarized circular tube transducers, a metal spacer block attached to one of the transducers, and a conical shell. The finite element analysis software COMSOL is utilized to investigate the modal changes in the system during power transmission, while also analyzing the impact of receiving transducer height and relative position on power transmission. Ultrasonic data communication experimental results demonstrate that reliable data can be transmitted across the conical shell using binary frequency shift keying modulation and demodulation techniques at a communication rate reaching 1kbps.

Aiming at the demand of the environmental adaptability and reliability of millimeter wave proximity fuze for the simulation test system of near-field backscattering characteristics of various backgrounds, such as land, green vegetation, and road surfaces. A simulation method for millimeter wave scattering characteristics of complex ground background is proposed. The method can realize both the background equivalent simulation in the energy dimension and the dynamic scene simulation in the time dimension, which solves the technical defects of the traditional simulation method for the dynamic test scene simulation. The test results show that the maximum error and the root mean square error of the two background simulations of grass and concrete pavement are less than 3dB, which meets the demand of simulating the dynamic detection response characteristics of various background millimeter wave near-field and provides a concise and efficient testing method for the practical performance assessment of ground proximity fuze.
