HF direction finding - this page is a stub

HF/DF, commonly known as huf-duf, is the abbreviation of High Frequency Direction Finding, and refers to a system that was developed in the UK during WWII, to quickly and accurately determine the position of enemy ships. The system is based on a 1926 development by Robert Watson Watt, and played an important role in the Battle of the Atlantic. It is estimated that contributed to 24% of all U-boats sunk during WWII [1].
