Singapore's captured radar specialists became a Japanese intelligence target

What technical resources and intelligence did Japan capture at Singapore?

Much of the equipment was destroyed, but Japan captured radar personnel and other specialists whose knowledge could assist its own development.

Singapore's surrender was managed well enough to destroy much of the material that might have been captured intact. The Japanese nevertheless took skilled technicians and an entire radar unit prisoner. Those specialists could be interrogated for information relevant to Japanese radar development even when the hardware itself had been denied. Their limited cooperation also shows why capturing expertise was different from acquiring a ready technical system.
