Extract

Using a Kelvin-Hughes radar photoplot an investigation of sea-clutter patterns on the radar screen was carried out during two voyages in the Atlantic during 1964 and 1965. A physical explanation of sea clutter has not yet been produced. The Use of Radar at Sea states (page 101): ‘In almost all sea conditions there will be an area of sea clutter around the ship. The fronts of waves give stronger echoes than the backs and therefore the clutter area will not be symmetrical about the ship.… If the movement of the sea is largely due to swell there will be a wider space between echoes although they will extend to some distance. Lines of rollers sometimes produce very distinct echoes.’
