The Japanese Type 32 or Mark 3 Model
2 was a fire control radar for warships. It used lobe
switching of a two-horn receiver to achieve directional accuracy. It
became available too late to help the surface fleet but was deployed as
a fire control radar for coastal artillery.
The Type 31 was a much heavier early version (5 tons) using a single
parabolic antenna, while the Type
33, which was never produced in quantity, was a lightweight version of
Type 32 weighing 1760 pounds (800 kg). None of the variants was
considered outstandingly successful.
