The escalating overlap between non-geostationary orbit (NGSO) and
geostationary orbit (GSO) satellite frequency allocations necessitates accurate
interference detection methods that address two pivotal technical gaps:
computationally efficient signal analysis for real-time operation, and robust
anomaly discrimination under varying interference patterns. Existing deep
learning approaches employ encoder-decoder anomaly detectors that threshold
input-output discrepancies for robustness. While the transformer-based TrID
model achieves state-of-the-art performance (AUC: 0.8318, F1: 0.8321), its
multi-head attention incurs prohibitive computation time, and its decoupled
training of time-frequency models overlooks cross-domain dependencies. To
overcome these problems, we propose DualAttWaveNet. A bidirectional attention
fusion layer dynamically correlates time-domain samples using
parameter-efficient cross-attention routing. A wavelet-regularized
reconstruction loss enforces multi-scale consistency. We train the model on
public dataset which consists of 48 hours of satellite signals. Experiments
show that compared to TrID, DualAttWaveNet improves AUC by 12% and reduces
inference time by 50% to 540ms per batch while maintaining F1-score.
