    Here is a potential test case to run the detection algorithm on.  I looked on the AIS stream and saw that there were 3 vessels in the area.  The Andre Jacob could be one of the vessels.

    WE follow the track of the MAAS TRADER down the south shore of New Jersey. And use the range files from LOVE and BRIG site to see if it was possible to detect it with the 5 mHz.

    The results using the IIR method and Median Method are as follow For LOVElove_iir_256_10

    These are the results for the BRIG site

    brig_iir_256_10

    brig_mdn_256_11

    Both sites detect ships but not the MAAS trader. It seems that the 5 mHz does detect ship but not the ship that we are looking for. I am doing more test and see if we can identify which ship the data is detecting.

  • Oleander and MAAS Trader

    This is the path of the MAAS trader and the Oleander for February 26 2009. The ships have different time track. The MAAS trader is traveling from 00:00 to 01:00 South heading to Brigantine. We lost the track between 01:00 – 03:00 and pick it up from 04:00 to 06:30.

    The track of the Oleander is from 22:00 to 24:00. In this case the ship is moving away from the Radar, heading south-east, from Seabright.

    In the next Figure is a comparison between the detection rate in SeaBright for the MAAS Trader and Oleander

    The following is for the Oleander in SeaBright.

    Take into consideration that is different time we do see different ships during that period of time. I need to identify which ships are and their characteristics.
