The instantaneity of a fuze refers to the time interval between the projectile's impact on the target and the completion of detonation. This parameter is a critical indicator for evaluating the performance of ammunition. To investigate the factors influencing instantaneity, a numerical simulation was conducted on the process of a projectile striking a target under different conditions, including impact angle, fuze material, and target material. The simulation results, under 12 different conditions, produced acceleration curves and instantaneity for the firing device. Through the analysis of the results, the study establishes key design principles for the firing device of the fuze: the protection design of the ignition device and the selection of the ignition strategy should consider the maximum and minimum impact angles and target hardness. Choosing an ignition device with a low structural strength or a fuze body material with lower hardness and strength can enhance the fuze's instantaneity The target hardness and impact angle greatly affect the fuze's instantaneity of the fuze, and appropriate structural strength should be selected in the design. © 2024 Institute of Physics Publishing.

Addressing the current challenges of weak target azimuth detection and inadequate precision in frequency modulated continuous wave (FMCW) radar systems, this paper proposes a novel method for precise imaging based on a motion array using FMCW radar for accurate range and azimuth estimation. The approach involves the use of a millimeter-wave FMCW radar with a motion array to capture target angular information, leading to a substantial improvement in azimuth estimation resolution, particularly for munitions. Additionally, spatial Fourier transform array signal processing is employed to achieve two-dimensional precise imaging of radar targets, encompassing both range and azimuth dimensions. Experimental results validate the effectiveness of the proposed approach, showcasing an enhanced angular resolution of the millimeter-wave radar, reaching 2.6°. The method demonstrates favorable azimuth estimation outcomes in diverse scenarios, including those involving multiple and planar targets. Overall, the introduced technique significantly elevates the precise detection capability of automotive millimeter-wave radar systems. © 2024 SPIE.

To assess the contradiction between ballistic safety and ignition reliability in traditional rocket projectile inertial initiation mechanisms, this study focuses on the recognition of graze bursting ignition signals for a specific type of rocket projectile. By utilizing a finite element numerical simulation method to model the small-angle impact of the rocket projectile on a target, the overload information can be extracted from the ignition mechanism. The accuracy of the simulation model can be validated by comparing it with data obtained from live ammunition tests. Through a series of simulations, the ignition threshold can be determined by the maximum velocity change vector within different time windows of the ignition mechanism. And the integration algorithm is used to accumulate the overload value of the ignition mechanism in the time window to judge whether the velocity change threshold is reached, and then judge whether to output the ignition signal. The algorithm verification shows that the algorithm can effectively identify the ignition signal under the set ignition threshold. This method provides a basis for recognizing the graze bursting ignition signal. © 2024 Institute of Physics Publishing. All rights reserved.

High voltage capacitor discharges serve as the primary source of pulse current in fuze electronic safety systems. This study explores the impact of high voltage capacitors on charging time, discharge time, and pulse discharge capacity in such systems, focusing on characteristics like leakage current and dielectric material. Through simulations of charging and discharging circuits, it was observed that the capacitor's voltage increases when the charging current surpasses the leakage current, eventually reaching a steady-state value when equilibrium is achieved. Analysis of polarization-electric field (PE) curves for various capacitor materials revealed that antiferroelectric material is the most optimal choice for high-voltage capacitors in fuze electronic safety systems, followed by linear material capacitors and ferroelectric material capacitors. Notably, the discharge power of antiferroelectric material capacitors was found to be approximately three times greater than the other two types, making them more conducive to fuze miniaturization. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

With the development of autonomous driving technology, the probability of mutual interference between automotive radars has significantly increased. Aiming at the increasingly serious mutual interference problem among automotive radars, an interference mitigation technique based on empirical wavelet transform and maximum correlation coefficients is proposed. The technique achieves the reconstruction of clean target signals from interfered original signals by constructing an adaptive wavelet band-pass filter bank, and then locates the target echo signal by the maximum similarity coefficient to achieve the reconstruction of the target echo signal. The effectiveness of this technique has been verified through simulation experiments, and the experimental results show that the proposed technique can significantly reduce the impact of interference. Compared with several existing technologies, it further demonstrates the superiority of the proposed technique. © The Institution of Engineering & technology 2023.

Aiming at the low operation rate of the firing mechanism of ammunition fuze, robustness analysis and probabilistic design methods were introduced into the fuze design to carry out system simulation research on performance prediction and optimization of the firing mechanism of ammunition fuze. In this paper, the dynamic model of the inertial impact switch of a proximity fuze is established, and the mechanism can be reliably triggered under nominal values by simulation method. Based on the Monte Carlo simulation of dimensional tolerance distribution, the trigger performance is evaluated. The contribution rate of each dimension variable to the target value is obtained by using the optimal Latin hypercube experiment design, and the variable tolerance with greater contribution rate is optimized by Pointer algorithm. After optimization, the range of variable Jdxh_f was optimized from 0.1274 to 0.1666 to 0.1274 to 0.1556. Finally, the optimized results were validated, with a uniform distribution yielding 0.003193517N, a bimodal distribution yielding 0.2230769N, and a normal distribution yielding *** validation analysis of these results shows that the target value distribution data after optimization meets the design *** study seeks a balance between performance reliability and manufacturing cost, which is of great significance to improve product performance and reduce manufacturing cost. © 2024 Institute of Physics Publishing.

Antennas with conical beams have the advantage in anti-interference applications. This paper proposes a low-profile antenna with two conical beams working at X and Ka bands. To save space, a Ka-band multi-ring antenna composed of one circular plate and five concentric rings is placed on the center of an X-band uniform circular array (UCA) antenna formed by eight microstrip patches. A vortex electromagnetic wave (VEW) with mode 1 is generated with the UCA antenna with phase difference of the elements of 45 deg. With different phase difference, the higher modes of the VEW can be formed. The cylindrical cavity not only serves as the cavity of the Ka-band antenna, but also physically separates the two antennas which makes them do not interference with each other. The peak gain at 37.5GHz of Ka band is 12.4dBi, and the 3dB beamwidth is in the range of 6.9-24.4deg. The peak gain at 10GHz of X band is 8.2dBi, and the 3dB beamwidth is in the range of 12.8-43deg. © 2023 IEEE.

To address the challenge of effectively evaluating ISAR image similarity under multi-precision fusion processing, this paper proposes a Fine-Grained Weighted Entropy (FGWE)-based image similarity evaluation method. This approach fully considers the subtle structural features in radar images by assigning different entropy weights to various regions, thereby emphasizing the differences of the important structural information and then reflecting accurately the similarity between images. Experimental results demonstrate that, compared with traditional methods, when FGWE was used to evaluate radar images, it showed a greater sensitivity to structural feature differences, and more accurately trapped the image information loss which derived from multi-precision processing. The mentioned FGWE reveals great potential in the field of radar image precision evaluation. © 2024 IEEE.

In this paper, a new type of dual-channel triangular planar capacitive sensor is proposed, which can overcome the problems of small dynamic detection range and low sensitivity in nondestructive testing (NDT) applications. By establishing a three-dimensional simulation model of the sensor, the influence of structural parameters such as excitation electrode, shielding electrode, protective electrode, and thickness of substrate on its various performance indicators was systematically analyzed using ANSOFT finite element analysis (FEA) software. By studying the corresponding relationships between different performance indicators and structural parameters, a mathematical relationship between penetration depth and electrode structural parameters was established, and the general design principles and methods for dual-channel triangular planar capacitive sensors were determined. Finally, through experimental verification, it was proven that the theoretical analysis results were consistent with the experimental results, providing a theoretical basis for the optimization design and application of the dual-channel triangular planar capacitance sensor. © 2024 SPIE.
