In this paper, the design and measurement of a mode-suppression circuit (MSC) applied in the nonlinear interaction region of a Ka-band gyrotron travelling wave tube (gyro-TWT) are presented. The proposed MSC is capable to suppress the spurious TE11 mode with no influence on the operating TE01 mode which helps to improve the tube stability for the high-power operation. Simulation result shows MSC can provide a loss of more than -5 dB around 23.1 GHz for the spurious TE11 mode which agrees well with the measured results. © 2023 IEEE.

With the development of gyrotron traveling wave amplifier, long-range high-resolution millimeterwave (MMW) imaging broadband radar has been developed rapidly. Nyquist theorem brings challenges to wideband radar signal sampling, and the hardware complexity and cost of the required equipment will increase significantly. Compression sensing (CS) takes advantage of the sparsity of the signal in the transformation domain. Under the condition that it is far less than Nyquist sampling rate, it uses random sampling to obtain discrete samples of the signal, and then perfectly reconstructs the signal through nonlinear reconstruction algorithm. This paper proposes a linear majorization sparsity adaptive matching pursuit (LMSAMP) algorithm based on CS theory. The LMSAMP algorithm with adaptive optimization step size selection is used to reconstructed two-dimensional image of wideband MMW radar. The imaging results show that LMSAMP algorithm has a good imaging effect. © 2023 IEEE.

In this paper, the design and measurement of a mode-suppression circuit used in the nonlinear interaction region for a G-band gyrotron travelling wave tube (gyro-TWT) are presented. By achieving sufficient coupling losses, this circuit can effectively suppress the parasitic oscillations without affecting the operating mode, thus improving the tube stability during high power operation. The measured results agree well with the simulated results, which can provide a loss of 5.6 dB/cm to suppress the backward-wave oscillation (BWO) of the TE21 mode. This proves that the circuit can be used as a new scheme for gyro- TWTs to achieve high stability and high power. © 2023 IEEE.

Range alignment is an important step in the imaging process of inverse synthetic aperture radar (ISAR) radar. In this paper, a novel deep learning network model is proposed to effectively tackle the challenge of distance alignment in millimeter-wave (MMW) ISAR imaging. The proposed model leverages a multi-layer bidirectional long short-term memory (bi-LSTM) network architecture to learn intricate features among echoes, thus facilitating precise alignment along the range direction. Meanwhile transfer learning was used to enhance the adaptability of the model to multiple signal-to-noise ratios (SNR). Experiment results show that the aligned images generated by proposed model in this paper are closer to the reference images in low SNR environments compared to traditional methods. ©2024 IEEE.

In this paper, an inverse synthetic aperture radar imaging method based on multiple norm constrained generalized orthogonal matching pursuit (MNGOMP) algorithm is proposed to improve the imaging process of inverse synthetic aperture radar is prone to noise interference in compressed sensing environment. Orthogonal matching pursuit (OMP) and generalized orthogonal matching pursuit (GOMP) converge slowly in radar imaging and are susceptible to noise interference. Therefore, multiple norm constraints were introduced into the iteration update to improve convergence speed and accuracy and enhance noise resistance. The results show that this method is effective in suppressing unnecessary clutter and enhancing desired target. © 2023 IEEE.

The Radio Frequency Fingerprint Identification (RFFI) technique utilizes the subtle and unintentional modulation present in the transmitted RF waveform, caused by the non-ideal characteristics of the device, to uniquely identify an emitter. RFFI has recently gained significant attention, and deep learning (DL) approach has achieved superior performance. In this paper, we study the DL-based RFFI with an emphasis on the fingerprint contamination by receivers. Specifically, during reception, the receivers' fingerprints are inevitably introduced, and different receivers affect emitters' fingerprints differently, thereby degrading recognition performance when the RFFI recognition model is deployed at different receivers. To mitigate the receivers' effect, we propose a receiver-independent recognition model based on the idea of feature disentanglement. With the aid of some carefully designed model structure, loss functions and training strategy, the proposed model learns a feature space, in which the emitters' features are disentangled from the receivers', through multi-receiver's training data. When deploying the model on a new receiver, the emitter-dependent features are exploited to achieve receiver-independent identification. Experiments on two real-world datasets demonstrate that our method significantly outperforms the baseline method without considering fingerprint contamination. © 2023 IEEE.

In this paper, we present state feedback control for the distributed radar with packet dropouts and time-varying delays. The delays are time-varying. The packet dropouts mean the loss of the state measurement data. Firstly, the state feedback control design is transformed into stability analysis for a 2D stochastic system. Secondly, we obtain the stability condition based on linear matrix inequality (LMI) of mean-square asymptotic stability of the 2D stochastic system. And we give the method to get the law for the state feedback control design. The proposed method can stabilize the distributed radar with packet dropouts and time-varying delays. Finally, a numerical example is to show the validity of the methods. © 2023 IEEE.

作者： Chen, Cong Long, Zixuan Nan, Fang Xiao, Luyao Zhu, Dijie Li, Xiang Liu, Ying Shao, Shihai National Key Laboratory of Science and Technology on Communications University of Electronic Science and Technology of China Chengdu China Telecom Research Institute Beijing China Glasgow College University of Electronic Science and Technology of China Chengdu China Laboratory of Electromagnetic Space Cognition and Intelligent Control Beijing China

Almost blank subframe (ABS) is a classic and efficient technology to cancel interference in cellular networks and could be applied in future networks such as ultra-density network. However, the existence of ABS will result in the deterioration of the communication capacity of the macro base station (BS), particularly for applications with large number of edge users. To solve this problem, an improved ABS technology with an interference cancelation scheme is proposed. For the considered scenario, the macro BS and the micro BS work in a cooperative manner, where the signal transmitted by the macro BS interferes with the communication between the micro BS and its edge terminals. At the terminal side, both the nonlinearity of the macro BS transmitter and the propagation model between the edge user and the macro BS are estimated using neural networks (NNs), which are then sent to the micro BS for interference elimination through the ABS. At the micro BS side, firstly, the nonlinearity and channel parameters from the ABS frame are used to generate a cancelation signal. Secondly, the cancelation signal is sent from the micro BS to the edge user to eliminate the disturbance from the macro BS. This enhanced technology can alleviate the disturbance for the edge user. Meanwhile, since it massively decreases the occupancy of ABS in the macro BS, the capacity of the macro cell can be improved. © 2023 John Wiley & Sons Ltd.

This paper presents a new method to achieve passive pulse compression using a lossless dielectric loaded waveguide (DLW). The method demonstrates an obvious performance in controlling the dispersion characteristics of the DLWs. Efficient pulse compression in a specific frequency range is achieved by varying the radius and thickness. In the simulation, the compression factor of 85.6 is obtained by compressing a linear frequency-modulated pulse with a duration of 20 ns and a frequency range of 34.8-39.8 GHz into a Gaussian-envelope pulse. © 2023 IEEE.

A compact sheet beam extended interaction oscillator (SBEIO) with frequency of 13.986 GHz is proposed in this paper. The model adopts a ladder structure with six gaps and operates in the TM11-2π mode. By optimizing the structure through the MATLAB program of the nonlinear theoretical simulation designed in our group, the efficiency is increased from 23.6% to 32.1%. The voltage and current of the electron beam are respectively 45 kV, 14 A. The current density remains at 50 A/cm2, which is suitable for the application of the periodic permanent magnet and beneficial for compact overall structure. The output power reaches 157 KW. © 2023 IEEE.
