MOANA

Maritime radar navigation and object detection

Seven fishing-boat and yacht sequences combine X-band and W-band scanning radar with stereo images, LiDAR and GNSS; Single Island includes 2D object boxes.

Sensor overview

High-level sensor availability before the detailed sensor records below.

Ground truth

Reference scope, method, rate, coverage, and provenance.

Ground-truth references for MOANA
Scope Method Reference system Count Rate Coverage Reference provenance
External
Measured using equipment independent of the platform’s normal onboard sensor pipeline.
Derived
Computed primarily from the dataset’s own recorded sensors.
Hybrid
Combines independent reference equipment with onboard measurements.

Accuracy notes
Signal reception failures cause significant positional drift; Port GNSS also has periodic delays. No verified numerical reference accuracy is established.
Reference notes
Reference uses the released GNSS positions; this is the same receiver listed as an input, not additional reference hardware. Refined ground truth obtained by optimizing all sensors is future work in this paper.

Calibration and synchronization

Calibration targets
Known pattern board for camera intrinsics; stationary planar objects for camera–LiDAR extrinsics.

Parameters only

Processed calibration parameters are reported, but raw calibration data is not reported.

Notes

Extrinsic text files use the GNSS base frame. Radar alignment uses image features, LiDAR–radar alignment uses phase correlation, and unobservable extrinsic components use CAD. Intrinsic calibration is described, but released intrinsic files and raw calibration recordings are not established.

Known or intentional limitations

Reported constraints and characteristics to check before using the dataset.

GNSS references contain positional drift and Port delays; refined ground truth remains future work.

Object annotations cover Single Island only, using one navigation-avoidance category and tracked 2D boxes.

X-band updates refresh one third of the image per second rather than delivering independent full scans at 1 Hz.

LiDAR is sparse outside berthing areas.

W-band data can be lost in Twins Island and predominantly blank in Outer Port.

Wave-induced wobble and multipath from large vessels challenge radar continuity and tracking.

Notes
Cartesian images. Adjusted range is 2498 m at 2.44 m/px for Port and 3328 m at 3.25 m/px for Island. These replace the nominal SDK range estimates. One third of each image is refreshed per 1 Hz update; a full rotation takes three seconds. Count describes one vessel setup, not a sum across both platforms.

Notes
Polar-coordinate images at 0.175 m/px. Port uses RAS6-DEV-A with horizontal rays; Island uses RAS6-DEV-X with rays reaching below radar height to suit the taller vessel. These are alternative vessel configurations represented as one family, not simultaneous extra units. The paper does not establish a released W-band frame rate.
