Abstract

Deployment and operation of autonomous underwater vehicles is expensive and time-consuming. High-quality realistic sonar data simulation could be of benefit to multiple applications, including training of human operators for post-mission analysis, as well as tuning and validation of autonomous target recognition (ATR) systems for underwater vehicles. Producing realistic synthetic sonar imagery is a challenging problem as the model has to account for specific artefacts of real acoustic sensors, vehicle attitude, and a variety of environmental factors. We propose a novel method for generating realistic-looking sonar side-scans of full-length missions, called Markov Conditional pix2pix (MC-pix2pix). Quantitative assessment results confirm that the quality of the produced data is almost indistinguishable from real. Furthermore, we show that bootstrapping ATR systems with MC-pix2pix data can improve the performance. Synthetic data is generated 18 times faster than real acquisition speed, with full user control over the topography of the generated data.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Sonar images obtained by a GAN accurately reproduced data obtained by a moving vessel, creating analogous distortions due to the moving sensor.

    “Sonar images were obtained by a GAN in [152] that accurately reproduced the data obtained by a moving vessel, creating analogous distortions due to the moving sensor.”

    From A Survey of Underwater Acoustic Data Classification Methods Using Deep Learning for Shoreline Surveillance (2022) · cites this paper as [152]

    The Training Data section (p. 2) says the GAN-based model generates sonar imagery using vehicle yaw to account for turn distortions. But Addressing Potential Concerns (p. 6) says yaw alone does not make the results fully realistic: the model produces very realistic turn distortions only in some cases. The claim overstates how accurately it reproduces data from a moving vehicle. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
