Fusing AIS data and SAR to enable global monitoring of dark vessels
How ICEYE and Spire allow you to fuse SAR imagery and AIS to enable the global monitoring of Dark Vessels.
Questions and answers
- Is the service able to distinguishing dark vessels that are stationary from the ones that are moving?
Yes, it possible if you can see the wake from the moving vessel in the image
- Can you explain more about the machine vision learning for SAR. How accurate is this at the moment (and explain the trajectory for when you think we will hit tipping points for detection). Especially with regards to size, weather conditions etc.
Machine vision is based on CNN. It is easily above >>90% but the challenging cases are the very small vessels (<20m) combined with bad weather conditions. ICEYE has a good resolution (3m) which makes it easier compared to other SAR satellites
- Can SAR detect wooden ships?
- How is the trial data or results provided to the customer?
Format is customer specific but can be e.g. WMS/WFS, KMZ, and proprietary formats.
- Can your service deal with areas of high density traffic and do you filter out SAR ambiguities?
We have monitored many densely areas like Singapore strait. No significant challenges. For more information on our High Traffic Zone Solution, see our D-AIS service
- What is the delay between SAR image acquisition and delivery of the image with vessel detection report?
Our target for the operational service is 30 minutes.
- What’s the resolution of the SAR image?
- Is there any sample processed SAR data available for download?
Yes, on the ICEYE website
- How well is it possible to differentiate/identify dark vessels?
You can measure size and see certain features of the vessel but identification with certainty relies on combination with other datasets.
- Which is the minimum size of the spottable vessels/objects with the highest resolution of SAR?
Typical minimum would be around 10m vessel.
