    i want to do a project on detection of icebergs, which is a major problem facing in ship sailing. is it possible to calculate density of materials using laser waves., such that it helps in detecting ice bergs from a distance.:confused::confused:

    Standard is radar which detects them at the very same distance than common targets like ships, islands, etc.

    For the "tabular" ones, the difference lies in the echo you see in the screen which looks like an angle instead of full shapes.

    BUt, in heavy weather, the small ones (very small compared to other bergs) called "growlers" could be not distinguished on the screen which is more or less cluttered with the echoes of waves. They rise very little from the surface and they are the most dangerous for a ship.

    As in open air, temperatures play an important role. Google for sonar and all related to transmission of signals through water.
