The Japanese Tachi-18 early warning radar (designed during development as the Type B Portable Early Warning Device or Chotampa Keika-ki Otsu, Ido-yo) was a mobile set resembling the American SCR-270. It was the most mobile Japanese Army early warning system, intended to replace the Tachi-7, but it was introduced too late in the war to be deployed outside the home islands.
The Taichi-18 was sometimes supplemented by the Taichi-20 for
height finders, operating at around 300 cm wavelength.
