  • Velocity Plots from the boat experiments

    Posted on July 19th, 2010 admin No comments

    This is the Velocity VS. Time plot from June 30, 2010 at 2pm in which the velocity of the Savitsky does not match with the radial velocity along the entire time. This is because the boat was not drive towards and away to the antenna all the time. As an example the time of 2:25pm was look in the GPS data to find the corresponding coordinates in the boat path.

    Here is shown were was the boat at this time. It clearly seen that it has a component of the velocity vector and because of that, the boat speed is different.

  • June 30 – AIS data plots

    Plots from the AIS data gathered during the morning and afternoon experiments on June 30, 2010. The time in the data is not changing, still have to figure out why.

  • AIS data from June 30 Morning Exercise

    Here is a plot of the AIS data from the morning of the exercise.  This gives you an estimate of the range of AIS data we are capable of receiving with the AIS receiver on the 6th floor of the Babbio building.

    This is the path the Steven’s boat should take in order to perform the next radar test.

  • Configuration of antennas , cables, and channels

    Posted on June 23rd, 2010 admin No comments

    Step 1

    First we assembled the antenna so that channel one was connected to cable one which was connected to antenna 0ne, channel three was connected to cable cable which was connected to antenna three. The result was that channel three had low signal.

    Step 2

    Second we connected channel one to cable one to antenna three, and channel three to cable three to antenna one. The result was channel one had low signal.

    Step 3

    Third we connected channel one with cable one with antenna one, and channel three with cable three to antenna three. The result was that channel three had low signal again. In this step we switched the legs of the antenna so that they were in the right configuration. one pointing up river and three pointing down river.

    This test concluded that the antenna three was the only component to have a low signal in all trials therefore antenna three is at fault for low signal not the cable or the channels.

    Antennas 1 and 2 are working good. However antenna 3 is not showing the correct spectra due to some problems with the antenna setup.


  • Changes made by Codar

    These parameters are ones that were used to get previous readings along with the new ones set to get current readings. These parameters change the range of the antenna and resolution of the data collected. We went from using low range high resolution data to using a much further range and less resolution.
