Maritime radar is used to survey shipping on waterways. In the simplest case, a primary radar system is used, emitting electromagnetic waves which are reflected at the walls of a ship. Employed frequencies range between 1 GHz - 2 GHz in the L-band, between 2 GHz - 4 GHz in the S-band and between 8 GHz - 12 GHZ in the X-band.
