Low-Altitude Economy Meets Safety Management: Leveraging a Multi-Attention High-Resolution Network for Enhanced UAV Detection
This paper proposes MAHR-Net, a novel multi-attention high-resolution network for enhanced UAV detection, particularly focusing on low-altitude, slow-speed, and small-sized multi-rotor UAVs. It introduces new modules like A2C2f, CAB, and SAB, integrates programmable gradient information training, and uses a small target replication method. Experimental results show state-of-the-art performance with 86.4% accuracy and 79.1% recall on the UAVD dataset, addressing critical safety management challenges posed by the growing low-altitude economy.

UAV Detection Results
Addressing the challenge of small-sized UAVs, MAHR-Net enhances resolution in the prediction head and employs a small target replication and augmentation method. This involves segmenting targets, scaling them, and placing them in background images to boost the model's detection and generalization performance for tiny objects, without complex training.
Enhanced
Small Target Detection Capability
The model utilizes Programmable Gradient Information (PGI) training to mitigate gradient loss in deep networks, ensuring the backbone retains comprehensive information. This, combined with data augmentation, leads to state-of-the-art performance. Experiments on the UAVD dataset validate its effectiveness, achieving 86.4% accuracy and 79.1% recall.
