Therefore, achieving automatic identification of tailings ponds is vital for resource supervision and ecological protection. However, due to the inherent morphological and textural complexity of tailings ponds in remote sensing images, existing general-purpose object detectors struggle to achieve accurate detection. To meet these challenges, this letter proposes a tailings ponds detection framework based on irregular attention features, which is targeted at both positioning and classification. Specifically, this letter introduces a context-aware location refinement module, which uses position encoding to serialize images to improve the positioning accuracy of irregular targets; and a part attention classification refinement module is designed to focus on the most discriminative local areas to achieve more effective texture feature extraction and classification performance improvement. For evaluation purposes, we constructed a remote sensing dataset containing tailings ponds and buildings. Compared with existing benchmark methods, our method achieves satisfactory performance in the tailings ponds detection task, providing a reliable technical support for efficient and automated monitoring of tailings ponds.","PeriodicalId":91017,"journal":{"name":"IEEE geoscience and remote sensing letters : a publication of the IEEE Geoscience and Remote Sensing Society","volume":"23 ","pages":"1-5"},"PeriodicalIF":4.4,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148492288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, due to the use of C/A codes of navigation satellites, which do not decay in range direction after pulse compression, significant direct path interference (DPI) is introduced in SAR images. Moreover, the low power of navigation signals further complicates the suppression of DPI. In this letter, a robust DPI suppression algorithm based on adaptive component extraction is proposed for GNSS-based InBSAR. First, a signal model of the DPI is established, and a coarse reconstruction of the DPI is achieved through parameter estimation after azimuth accumulation. Subsequently, based on the reconstructed DPI, an adaptive extraction of the direct path component from the echo signal is performed to suppress the DPI while preserving the target echo. Using raw data from BeiDou satellites, the proposed algorithm improves the signal-to-interference ratio (SIR) from 8.27 to 16.11 dB and enhances the deformation accuracy of the interference area by 58.7%.","PeriodicalId":91017,"journal":{"name":"IEEE geoscience and remote sensing letters : a publication of the IEEE Geoscience and Remote Sensing Society","volume":"23 ","pages":"4008005-4008005"},"PeriodicalIF":4.4,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148493142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent SAM3-based methods provide a promising training-free foundation; yet, three key issues remain: 1) a single class-name prompt lacks sufficient semantic coverage for complex remote-sensing categories; 2) expanding each category into multiple prompts introduces redundant online text encoding; and 3) directly aggregating multiple prompt responses propagates noisy activations into the final prediction. To address these issues, we propose ProC-SAM3, which calibrates SAM3’s prompt interface for remote-sensing OVSS from three complementary aspects. First, we construct an offline prompt pool where a category matcher (CM) groups MLLM-generated candidates into per-category sets, and expansion constraints further refine each set using category-specific prior knowledge. Second, the resulting text embeddings are cached and reused across all test images, eliminating repeated text encoding. Third, we introduce presence-guided residual fusion (PGRF) to gate unreliable decoder outputs by prompt presence and confidence, followed by peak-preserving class aggregation that retains fine-grained activations for small and sparse objects. Experiments on eight benchmarks show that ProC-SAM3 achieves an average mIoU of 56.1%, outperforming the previous best training-free method by 3.9 percentage points.

We propose a Mamba-based frequency-domain enhanced network, termed Mamba-based frequency-domain enhancement infrared small target detection network (MFDENet). Specifically, to enhance target contrast and preserve fine-grained details, we propose a dual-domain feature complementary module (DD-FCM), which dynamically fuses complementary information from the original and enhanced domains. In addition, to utilize frequency-domain priors, we introduce a Mamba-based frequency-domain feature extractor that separates noise patterns from target components in the frequency domain and captures long-range dependencies among frequency coefficients. By integrating contrast-enhanced spatial features with robust frequency-domain representations, MFDENet improves the detection of weak infrared targets.

However, during the optimization process, conventional RPCA algorithms may distort the target phase information, resulting in the separation of target detection and parameter estimation. In addition, strong scatterers may lead to a high false alarm rate in target detection. To address these challenges, a structured constraint-based RPCA (SCRPCA) algorithm is proposed. On the one hand, the rank-one property of clutter is utilized to replace the conventional low-rank constraint; on the other hand, the sparse target component is reformulated as the product of amplitude and phase terms, enabling simultaneous target detection and parameter estimation. Furthermore, the along-track interferometry (ATI) phase is incorporated as a weighting factor to suppress clutter energy leakage. The block coordinate descent (BCD) algorithm is employed to solve the proposed optimization model.
