Japanese early radars?

[Rising-Sun]

Been doing some research on what kinda of radar or equipment did Japanese had on earlier days. Does anyone have any infos I could use? Going back like in the 30's, range finder or some kinda of fire control devices.

Rikugun Volume 2 Weapons of the Imperial army & Navy has a chapter on Anti-Aircraft Detection Equipment. It can be bought on amazon at a decent price.

AFAIK the Japanese were far behind in radio technology and had not started much research on radar until the war started and the Germans let them have a peek.
They had large, fixed listening horns to try and detect aircraft a dozen miles out. Nothing as big as the British ones that could hear Nazi bombers warming up their engines on the ground in Northern France (when the winds were right).

A TOP SECRET Japaneses radio message intercepted and decoded by the Allies Oct.1942.


Where are they driving to and Who is this Brenda LEE? ....GENDA? A code within a code?

Baby?.... the nickname of the BB Yamato ?

I've been drivin' all night, my hand's wet on the wheel
There's a voice in my head that drives my heel
It's my baby callin', says I need you here
And it's a half past four and I'm shiftin' gear
When she is lonely and the longing gets too much
She sends a cable comin' in from above
Don't need no phone at all
We've got a thing that's called radar love
We've got a wave in the air, radar love
The radio is playing some forgotten song
Brenda Lee's comin' on strong
The road has got me hypnotized
And I'm speedin' into a new sunrise
When I get lonely and I'm sure I've had enough
She sends her comfort comin' in from above
We don't need no letter at all
We've got a thing that's called radar love
We've got a light in the sky, radar love

The Japanese also had underwater sound detection. I've posted some links in another post before.

The shrimp were interfering with this device.

Japanese radar and related weapons

the Japanese tried to create a death ray called Ku-Go which utilized large-scale microwaves to create a focused beam of radiation.

Official U.S. report on the japanese death ray experiments



Poisons, chemical and biological weapons were also on the menu. For its biological weapons research it had ties to Unit 731. The laboratory was also the birthplace of the Fu-Go balloons and they were built at the same complex. At its peak it employed 1,000 scientists and workers. As Meiji University professor Akira Yamada said in an article in the Japan Times:



“The laboratory was not only kept secret from outsiders, but was so compartmentalized that even the people who worked inside had no idea of what was being done in other sections…”

There was no technological reason why Japan could not have developed radar and advanced cryptographic capabilities on the same timescale as America, but these did not fit into the IJN's scheme of things. Of course radar would have been very valuable to their navy, and so would more secure communications. But they were ideas not likely to occur to general line naval officers, and the specialists who might have spawned them were kept on a short leash.

A downside of all Japanese naval radars that the Japanese did not develop a combat information center (CIC - radar info interpretation/analysis center) nor a Fighter Direction Center linking that information to fighters defending the fleet. The usefulness of the information provided by their radars was pretty much determined by the individual ship captain and depended to a large extent on the understanding of the information by that individual. That downside extended until the Japanese surrender at which time some of the "unemployed" IJN ship commanders were studying the implementation and training requirements for such a scheme.
