1. A non-transitory computer-readable medium having stored thereon a plurality of computer-executable instructions which, when executed by a computer, cause the computer to:
receive, at a server, radar data for a marine environment from a scan performed by a radar sensor associated with a vessel, wherein the radar data is formed from one or more radar return signals received by the radar sensor during the scan, wherein the radar data indicates one or more objects in the marine environment; process, at the server, the radar data to identify one or more moving objects by:
comparing the radar data with at least second radar data from a second scan performed by the radar sensor to determine, based on the relative position of each object between the radar data and the at least second radar data, whether the one or more objects indicated by the radar data are substantially stationary or moving;determining, using Doppler data associated with the marine environment, if any of the one or more objects indicated by the radar data are moving based on if any of the one or more objects has a non-zero radial speed indicated by the Doppler data; ordetermining, using automatic identification system (AIS) data associated with the marine environment, if any of the one or more objects in the radar data are moving based on if any of the one or more objects matches a vessel identified by the AIS data; remove, at the server, any identified moving objects from the radar data to form remaining radar data; and generate, at the server and based on the remaining radar data, a map of the marine environment for display such that one or more substantially stationary objects are present in the map and the identified moving objects are not present in the map. |
