A Deployment-Oriented Real-Time Transformer Detector and Benchmark for Maritime Search and Rescue Under Severe Sea Clutter
This paper introduces R-DET, a real-time Transformer detector designed for maritime search and rescue (SAR) operations, particularly for detecting targets under severe sea clutter and strict latency constraints. It proposes a novel benchmark dataset, MarineRescue-8K, with an ignore-region protocol for robust evaluation. R-DET achieves a strong balance of accuracy, efficiency, and robustness through its three key components: Rescue-Net (lightweight multi-scale backbone), Rescue Attention (clutter-suppressed global context modeling), and Rescue-FPN (efficient high-resolution feature fusion). The experimental results demonstrate R-DET's superior performance across various maritime conditions and its transferability to public benchmarks.

Bounding Box Predictions
MarineRescue-8K is a new benchmark dataset collected from real maritime operations. It features 8390 images with 18,650 annotated instances across five rescue-critical categories (swimmer, life_saving_appliances, boat, jet_ski, buoy) and an 'ignored' category for non-critical clutter. A mission-aligned ignore-region protocol reduces the influence of irrelevant clutter during training and evaluation, making it suitable for practical SAR perception under extreme scale variation and heavy sea clutter.
Impact: Provides a robust and realistic dataset for evaluating AI models in critical maritime rescue scenarios, enhancing the reliability of autonomous systems.
R-DET achieves a significant performance lead over existing methods, showcasing its effectiveness in challenging maritime SAR scenarios.

mAP@0.5 on MarineRescue-8K
R-DET demonstrates superior robustness against environmental degradations like Gaussian noise, motion blur, and low illumination compared to the RT-DETR baseline.
| Perturbation Type | RT-DETR (mAP@0.5%) | R-DET (mAP@0.5%) |
|---|---|---|
| None (Clean) | 82.5 | 84.1 |
| Gaussian Noise (Medium) | 72.3 (-10.2) | 78.5 (-5.6) |
| Motion Blur (Medium) | 68.1 (-14.4) | 75.4 (-8.7) |
| Low Illumination (Medium) | 74.5 (-8.0) | 79.8 (-4.3) |
Despite its enhanced accuracy and robustness, R-DET maintains real-time inference capabilities, making it suitable for deployment on resource-constrained platforms.

The R-DET framework is specifically tailored for maritime SAR, considering real-world constraints such as extreme scale variation, heavy sea clutter, and strict computational budgets.
Optimizing for Real-World SAR
This design philosophy ensures R-DET is not just theoretically sound but practically deployable in critical scenarios.
- Lightweight multi-scale representation (Rescue-Net) preserves tiny-target cues.
- Clutter-robust global context modeling (Rescue Attention) suppresses sea clutter.
- Efficient high-resolution cue propagation (Rescue-FPN) enhances small-target detection.
- Mission-aligned ignore-region protocol reduces false positives from non-critical clutter.
