The Type 279 radar was a British naval early warning radar developed during World War II from the Type 79.[1] with metric air warning set. It had separate Tx and Rx antennas, combined in Type 279M to single antenna operation. This set also had a secondary surface search with surface and aerial gunnery capability and used a Precision Ranging Panel, which passed accurate radar ranges directly to the HACS table (analog computer).[2][3]
