ORIGINAL: Mifune That is not the same set that I am thinking of. I seem to remember them capturing a land based air search set. Which they "copied" which is there first production air search set. Later on in the war when the Allies captured one of those Japanese sets. They investigated its inner works, they had realized that was just a crude copy of by then an older Allied set. I will see if I can remember the source once I get back home from work. This sounds like confusion of two different things captured at Singapore. The 40mm Bofors was captured there - and indeed was "copied" - and put into production. But not as is - it was "improved" - over a long period - and went into production too late to matter - with only trivial improvements. Radar was developed in secret by EVERY maritime power - before WWII - including Germany, Japan, France, Russia, Britain and the USA. The Japanese had two entirely different and unrelated radar lines - Army and Navy. A worker on one line was forbidden even to speak to a worker on the other! This did eventually change - Japanese submarines finally got radar - an adapted Army set! - but that was well into the war. There is no evidence I am aware of that any entire radar was ever copied - and Japanese radar is so different from Allied it would be pretty clear if this was not the case. Frankly, Japanese radar is based on lower power transmitters, and generally lower gain recievers, and other issues which make it impractical to copy a radar - unless they somehow could copy the basic parts (e.g. pentodes). What IS stated (in the US FM Handbook on Japanese Forces - I think) is that Japan used US vacuum tubes. Copies of early triodes and diodes mostly. Similarly, RADIOs, while generally developed in Japan, also included some copied models. Perhaps this is causing confusion?
