Think about a radar pulse as a tennis ball. In case you fall the ball on to the floor beneath you, it will eventually bounce back to the fingers. Should you drop the ball onto an angled floor it will bounce away from you. Minimal RCS ship structure follows exactly the same principle. The vital when coming up with a very low RCS warship is guaranteeing which the superstructure has surfaces angled in order to avoid transmitting echoes again for the radar. This typically embraces the usage of flat, angular surfaces rather then curves. Curves are problematic. It's because at least just one issue on the curve will reflect straight back again towards the radar. Radar Absorbent Elements
RCS reduction procedures tend not to make a warship invisible to radar. As an alternative, they make her more difficult to detect. One particular resource shared an illustrative anecdote Along with the writer. They were being serving as the captain of a big surface area combatant in the NATO navy. The ship was approaching port and making ready to receive a pilot. The pilot’s boat was Geared up with a normal maritime navigation radar.
