Seetakt was a shipborne radar developed in the 1930s and used by the German Navy (Kriegsmarine) during World War II. It is the first naval radar to enter service, and among the earliest radars of any sort. It provided range measurements with an accuracy on the order of 50 metres (160 ft), more than enough for gunnery. Its angle accuracy was not very good, but the development of lobe switching specifically for this radar provided about 1 degree accuracy, not enough to directly lay the guns, but still useful for initial plotting and aiding the optical spotters find their target.
