摘要：Electromagnetic (EM) vortex waves carrying orbital angular momentum (OAM) have a helical wavefront structure, which allows the echo signal to contain the azimuthal information of the target when performing radar detection tasks, thus they show great potential in the field of staring imaging. It has been demonstrated that EM vortex radar (EMVR) based on the uniform concentric circular arrays (UCCAs) achieves equal divergence angles, so that the target can be simultaneously illuminated by multimode OAM beams. However, the imaging performance of EMVR is affected by the Bessel function term, which makes it difficult to achieve focused imaging results under limited OAM modes and apertures. To address this issue, a fast and high-resolution method based on accelerated 2-D alternating direction method of multipliers (2-D-ADMM) is proposed. First, an imaging model based on beam steering is established to effectively improve the detection performance, and the elevation resolution and azimuth resolution for EMVR are der

2. ISAR Imaging for Maneuvering Target Based on Suitable CPI Extraction and PC-MBSBL

[学者论文] RS评分：0

《IEEE Transactions on Aerospace and Electronic System》2024年 60卷 60期

摘要：In radar system, the maneuvering targets undergoing significant angular motion pose a challenge for motion compensation, thus an inverse synthetic aperture radar (ISAR) imaging framework has been proposed to obtain focused ISAR images under sparse aperture conditions. Due to the nonstationary Doppler frequency induced by the targets’ complex motion, the conventional range-Doppler algorithm suffers from performance degradation. Therefore, we propose a suitable coherent processing interval (CPI) extraction method to find out the relatively stable Doppler range. Since the fact that the extracted CPI typically contains too limited pulses to generate highquality ISAR images, a block-sparse signal recovery method based on pattern-coupled sparse Bayesian learning strategy for matrix block is further developed, which introduces the improved pattern-coupled hierarchical Gaussian model as the sparse prior to reconstruct the scattering coefficient. Specifically, the sparsity of each coefficient is represented by the hyperparameters corresponding to its eight adjacent coefficients, rather than solely by its own hyperparameter. The proposed prior model provides flexibility in modeling any block-sparse signals, and facilitates the generation of block structures. The experimental results using simulated data and measured data demonstrate the validity and superiority of the proposed method.

3. Enhanced SAR Imaging Using Multiple Plane Spiral Orbital Angular Momentum Beams

《Measurement》2022年 202卷期

摘要：We investigate the application of vortex beams carrying different orbital angular momentum (OAM) modes to SAR systems. For the traditional OAM-carrying wave, the inconsistent divergence angles exhibit that it is difficult to simultaneously illuminate the target with different OAM beams, resulting in limited echo energy or deterioration of the imaging capability. In this work, an enhanced SAR imaging method is proposed, which exploits plane spiral OAM (PS-OAM) to form a pencil beam and eliminates the above negative effects. First, the echo signal model for conventional vortex SAR is derived. Second, the feasibility of PS-OAM-based beamforming techniques for high-resolution SAR imaging is analyzed. Third, in light of the echo model of the proposed vortex SAR, an improved chirp scaling (CS) algorithm is provided by considering amplitude correction and phase compensation. Finally, the numerical simulations demonstrate the proposed method can achieve high-precision focusing processing in comparison with the traditional algorithm.

摘要：Vortex electromagnetic (EM) waves carrying orbital angular momentum (OAM) have a helical phase front and a field strength with a singularity along the axial center, which is expected to obtain resolutions beyond the Rayleigh limit for imaging systems, and provide new instruments for accurate radar targets imaging. However, since the vortex EM beams feature a doughnut-like intensity profile with a central dark zone and the inconsistent divergence angles of the main lobe, it is difficult to simultaneously illuminate the target for vortex EM beams with different OAM mode, which results in limited echo energy. In addition, the restricted elevation resolution hinders the acquisition of target spatial information, which limits the development of the OAM-based radar detection technique. This contribution offers a new set of ideas and solutions for achieving the 3D ISAR imaging using the superposition of different plane spiral OAM (PSOAM) waves. First, eigenmode beam steering techniques based on radio PSOAM waves is introduced. Subsequently, the PSOAM-based ISAR imaging model for maneuvering targets is derived and the echo characteristics are analyzed. Third, the effective imaging method, based on the amplitude phase compensation and fast Tensor-SL0 reconstruction algorithm, is proposed to solve the 3D sparse imaging problem in a tensor way. Finally, simulations are carried out to verify that the proposed method not only significantly reduces the computational complexity of the image reconstruction, but also generates the 3D image with sidelobes and artifacts removed remarkably from sparse measurements.
