This study introduces a data-driven approach for state and output feedback control addressing the constrained output regulation problem in unknown linear discrete-time systems. Our method ensures effective tracking performance while satisfying the state and input constraints, even when system matrices are not available. We first establish a sufficient condition necessary for the existence of a solution pair to the regulator equation and propose a data-based approach to obtain the feedforward and feedback control gains for state feedback control using linear programming. Furthermore, we design a refined Luenberger observer to accurately estimate the system state, while keeping the estimation error within a predefined set. By combining output regulation theory, we develop an output feedback control strategy. The stability of the closed-loop system is rigorously proved to be asymptotically stable by further leveraging the concept of λ-contractive sets.

This paper designs a K-band two-dimensional beam scanning liquid crystal reflective array based on sub-array division. The phase shifting unit adopts a "工"-shaped dipole structure, and a new sub-array division arrangement is adopted, by dividing the 24×24 liquid crystal reflective array into three parts, namely, the smallest phase shifting unit, 2×2 sub-array unit, and 3×3 sub-array unit, reducing the number of feedlines and achieving two-dimensional beam scanning. Simulation results show that the 24×24 reflective array designed in this paper, with the new sub-array division arrangement in the K-band, achieves a ±40° beam scanning in the E plane and H plane, and the array gain can maintain above 20dBi, with good directionality and side lobe levels below -5dB. © 2024 SPIE.

Multi-sensor multi-target tracking (MTT) with dense group clutter is facing great challenges in data fusion. One is the high computational complexity caused by the dense group clutter;another is that existing fusion algorithms do not have uniform fusion guidelines. To handle these problems, we present a novel multi-sensor MTT algorithm in this paper, which is based on the generalized labeled multi-Bernoulli (GLMB) filter and distributed deep neural networks (DNN) track fusion under the multi-sensor (MS) system, named the MS-GLMB-DNN algorithm. Firstly, a clutter pre-processing is elaborated, it is based on a CFDP (cluster by finding density peaks) algorithm to reduce the effect of the dense group clutter. Then, the GLMB filter is applied to the DNN track fusion framework for effectively fusing various local tracks. Experimental results indicate that, compared with the commonly used covariance intersection (CI) fusion algorithm, the proposed algorithm can effectively eliminate the effect of clutter on target tracking results, reduce computational complexity, and improve tracking accuracy. © Beijing HIWING Scientific and Technological information Institute 2024.

A novel ultra-wideband electrically small antenna based on an active matching network is presented in this paper. The proposed structure mainly consists of a folded butterfly dipole antenna based on distributed resistive loading and a non-foster circuit. The characteristics of the antenna structure and the interrelationship between high Q and bandwidth efficiency limit the application of passive matching techniques in electrically small antennas, and in this paper, Non-Foster circuits and distributed resistors are applied to the matching design of electrically small antennas to theoretically overcome the above challenges. The active matching network enables the matching of the input impedance of the small antenna up to 50 Ω with an impedance bandwidth (IBW) of 30 octave (0.051.5 GHz) at| S11| © 2023 IEEE.

To address the problem that the model-driven algorithms have the limited expression ability and are difficult to deal with the target maneuvering in time, this paper presents a maneuvering multi-target intelligent tracking (M-MTIT) algorithm based on deep long short term memory (DLSTM) and dynamic association gate, called the M-MTIT-DLSTM algorithm. Firstly, to track multiple targets, the proposed algorithm uses a prediction network and an update network based DLSTM, and defines the association gate by using the residual and corresponding covariance. Secondly, the valid measurements are extracted, and then the global nearest neighbor (GNN) algorithm is adopted to associate the data. Finally, the cardinal distribution theory is used to design a dynamic association gate, which can clear the accumulated historical states and historical measurements. Subsequently, the tracking process of the target is restarted when a maneuver is determined. Simulation experiments demonstrate that the proposed M-MTIT-DLSTM algorithm is more robust near moments of the target maneuver, and the tracking accuracy is close to that of the interacting multiple model (IMM) algorithm with high operational efficiency compared with the current widely used IMM algorithm. © Beijing HIWING Scientific and Technological information Institute 2024.

A miniaturized ultra-wideband antipodal vivaldi antenna (AVA) for lower frequency bands which works in the 0.5 3GHz band is proposed. The size of the antenna is reduced to only 150mm (length) *150mm (width) *1mm (depth) and the radiation performance of the antenna is improved by the following four miniaturization and high gain methods: arc-shaped slot, elliptical disk, director and reflector. The simulated results show that S11 is lower than -7.35dB in the full band and the maximum in-band gain of the antenna is greater than 0.5dBi. © 2023 IEEE.

This paper deals with the suppression problem of mainlobe digital radio frequency memory (DRFM) jamming especially for intra-pulse slice forwarding jamming for phased array radar. A novel mainlobe DRFM jamming suppression method resorting to blind source separation based on tensor decomposition (TD-BSS) is proposed to separate the target echo signal and jamming signal. Specifically, the received signals are reconstructed into higher-order tensor form. Further, the separating matrix optimization problem relying on tensor Canonical Polyadic (CP) decomposition principle is formulated and then solved by an enhanced line search alternating least square (ELS-ALS) algorithm. Finally, the performance of the proposed method is demonstrated through numerical simulations, showing its superior to suppress mainlobe DRFM jamming over the exiting method in terms of interrupted sampling and cyclic repeater jamming (ISCRJ) and chopping and interval (C&I) jamming. © 2023 IEEE.
