The Tachi-4 was a land-based gunlaying radar intended to replace the Tachi-1 and Tachi-2. It was known in prototype as
the Mark Ta Model 4 (Chijo-yo Dempa
Hyotei-ki, 4-gata) and was based in part on a captured British gunlaying radar from Singapore. The original dipole
elements were replaced with Yagi arrays, the center array acting as the
transmitter and the four other arrays being partially electronically
steered.
