In modern geophysical exploration, the semi-airborne transient electromagnetic method (SATEM) has become a key technique for conducting rapid surveys over large and hard-to-reach areas. However, field-captured signals are often severely contaminated by complex noise from various environmental and operational sources, compromising the accuracy of subsequent inversions and the interpretation of subsurface electrical structures. Traditional denoising methods rely heavily on manual parameter selection strategies, proving insufficient in real noisy environments. With the advent of deep learning, various neural networks have been applied to SATEM signal cleaning, but most use single-mapping approaches that fail to effectively separate signal from noise, capturing partial information and lacking interpretability.
To overcome these limitations, DREMnet emerges as an interpretable decoupled representation learning framework that decomposes data into two main factors: content and context. This separation enables robust noise treatment under complex conditions while maintaining process traceability. Unlike conventional CNN and Transformer architectures, DREMnet uses the innovative RWKV architecture for data processing and introduces the Contextual-WKV mechanism, which transforms unidirectional WKV modeling into bidirectional signal modeling. Additionally, the Covering Embedding technique preserves the strong local perception of convolutional networks through stacked embeddings. Experimental results on test datasets show that DREMnet outperforms existing techniques, and processed field data more accurately reflects the theoretical signal, improving the identification of subsurface electrical structures.
The application of DREMnet not only represents an advance in geophysical signal processing but also opens the door to new possibilities in developing intelligent noise removal systems. Companies like Q2BSTUDIO, specialized in custom software, can integrate frameworks like DREMnet into tailored solutions for the exploration and environmental monitoring industry. Q2BSTUDIO’s expertise in artificial intelligence and AI agents allows building systems that automate SATEM data preprocessing, reducing manual intervention and increasing interpretation reliability.
