[astro-ph.IM] Building on prior FAST targeted and blind SETI campaigns toward 33 exoplanet systems, we introduce a wavelet-integrated search pipeline for narrowband technosignature candidates in radio dynamic spectra.
![Robustness gallery (left to right). Yellow boxes denote detections morphologically classified as linear, while red boxes indicate signals with curvature. (a) Target drifting narrowband track + broadband impulsive transient, with the corresponding MSWNet cleaned map and predicted box. (b) Target + curved interfering track, with the cleaned map and predicted box. (c) Target + quasi-sinusoidally modulated interference, with the cleaned map and predicted box. (d) Target spanning patch boundaries (tiling), with the stitching result across patches. The brightened area is overlapping region and the green box is the equivalent detection obtained after cross-patch stitching. -- [astro-ph.IM]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/07/A-Wavelet-1.png?resize=1200%2C712&ssl=1)
