However, the detection range of individual satellites is limited, presenting challenges in fulfilling the task of continuous indication of targets. Joint exploration using multiple sensors is a more effective choice. Therefore, we propose a multi-target tracking and localization algorithm based on cooperative detection using multiple infrared sensors. This algorithm enables an integrated process from image plane tracking to three-dimensional spatial localization of small target groups. Firstly, we propose a multi-target tracking method using an improved discriminative correlation filter as the tracker. The method sets an energy concentration threshold based on the characteristics of infrared small targets to suppress background noise. Simultaneously, the minimum Euclidean distance and velocity similarity between consecutive frames of targets are used to associate the trajectories, effectively reducing association errors. In addition, an adaptive extended Kalman filter algorithm is synchronized to predict the target positions, addressing the challenge of small targets being easily occluded. Subsequently, an adaptive weighted covariance intersection fusion algorithm is employed to integrate multi-sensor information of tracking, effectively mitigating the issue of reduced localization accuracy caused by instability or tracking errors in individual sensors. Experimental results show that the mean Optimal SubPattern Assignment of the proposed tracking method is less than 0.2 pixels in simulated multi-target scenarios. The proposed multi-sensor fusion algorithm ensures localization accuracy within 44 m for detection ranges exceeding 4000 km. This highlights its potential in the fields of space exploration and target indication.</div></div>","PeriodicalId":13549,"journal":{"name":"Infrared Physics & Technology","volume":"152 ","pages":"Article 106188"},"PeriodicalIF":3.4,"publicationDate":"2025-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145321553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing multispectral absorption strategies often suffer from insufficient cross-band performance compatibility, limited integration of structural and functional design, and challenges in achieving conformal adaptability. These limitations hinder their application in scenarios requiring the suppression of internal crosstalk between high-frequency (terahertz) and low-frequency (microwave) signals. We propose and demonstrate a dual-spectrum absorption approach combining nickel-zinc ferrite (Ni₀.₇Zn₀.₃Fe₂O₄)–polydimethylsiloxane (PDMS) composites and tailored structures. The ultrathin absorber achieves reflection loss (RL) values below − 10 dB across two distinct frequency ranges: involving X- and Ku-band (0.08 λ_L, where λ_L is the wavelength at 10.52 GHz) and 0.25–1.1 THz, with RL &lt;  − 20 dB in the 0.82–1.1 THz range. Terahertz (THz) absorption is driven by diffraction-induced energy localization while microwave absorption stems from intrinsic dielectric/magnetic properties. Additionally, the single layered cylindrical cavity-based absorption units enhance THz absorption capabilities in the THz functional block with robust angular tolerance (≤60° incidence), achieving 95 % relative bandwidth for RL &lt;  − 15 dB at normal incidence. This significantly outperforms single layered square units (45° max incidence, 72.7 % relative bandwidth), attributed to the added absorption cavity effect.

It is widely used in maritime surveillance systems and reconnaissance systems, with significant potential for civilian applications such as security monitoring, forest fire detection, and power equipment inspection. However, detecting infrared weak targets in low-resolution images faces challenges such as small target size, sparse texture information, complex backgrounds, and low signal-to-noise ratio(SNR). Inspired by the positive impact of super-resolution on target detection, we introduced an improved version of the classic Temporally Selective Regularized Least Mean Squares (TSR-LMS) video super-resolution algorithm to enhance target detection performance. To further reduce noise introduced by registration errors, we employ the Demons registration algorithm to address nonlinear transformations between adjacent frames. The effectiveness of our algorithm is validated on publicly available infrared target detection datasets and real image sequences captured by infrared cameras. Experimental results demonstrate that the method effectively suppresses background clutter interference while improving target signal-to-noise ratio. To further validate the effectiveness of the algorithm, we selected several representative infrared small target detection algorithms and performed target detection on image sequences from multiple different scenarios, comparing the detection results before and after reconstruction. The results demonstrate a significant improvement in the average AUC of the reconstructed images across image sequences from various scenarios. Thus, our method significantly enhances the detection probability of traditional single-frame and multi-frame target detection algorithms while reducing their false alarm rate, demonstrating broad application prospects in infrared target detection.</div></div>","PeriodicalId":13549,"journal":{"name":"Infrared Physics & Technology","volume":"152 ","pages":"Article 106178"},"PeriodicalIF":3.4,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145321560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite substantial progress, existing fusion approaches often struggle to maintain a balance between semantic consistency and structural integrity, particularly under complex degradations such as low-light noise, modal interference, and cross-scene variability. To address these challenges, we introduce DSSFusion, a novel dynamic expert-guided fusion framework designed to enforce semantic-structural consistency under challenging conditions. The framework is anchored by three key innovations. First, the Dynamic Robust Mixture of Experts (DRMoE) module combines wavelet decomposition with a multi-expert architecture, dynamically adapting feature representations to modality-specific degradations using degradation cues generated by a LoRA-finetuned CLIP model. This allows for improved structural fidelity and robust generalization across scenes. Second, we develop a Self-supervised Semantic Segmentation Head (S<span><math><msup><mrow></mrow><mrow><mn>3</mn></mrow></msup></math></span>Head) that generates pseudo-labels without requiring manual annotations, effectively guiding the fusion network to maintain semantic coherence and reduce the impact of degradation-induced semantic drift. Third, the proposed Bidirectional Reconstruction Consistency Loss (BiRecLoss) introduces dual reconstruction pathways from the fused image to the original modalities, enforcing reconstruction fidelity at both pixel and gradient levels and preserving fine structural and textural details. Comprehensive evaluations were conducted on four representative multi-degradation image fusion datasets, comparing DSSFusion against eight state-of-the-art methods. Quantitative results demonstrate that DSSFusion outperforms existing approaches across multiple metrics—including image sharpness (AG, SF), information entropy (EN), and structural consistency (VIF, Qabf)—achieving a total of 22 top-3 rankings (15 first-place results) across the datasets. Moreover, DSSFusion exhibits outstanding performance in downstream tasks such as semantic segmentation and object detection, highlighting its strong perceptual capability and practical application potential in real-world multimodal systems.
