[TEC] What is the status of Japanese radar in 1.3?

[LukeFF]

From reading certain posts in the main SH4 forum, it looks like Japanese radar might still need to be tweaked in order to represented realistically (e.g., is their air search radar still picking up surface contacts?) From Combinedfleet.com:

Type 21

Became Operational: August 1943
War Status: used operationally in war
Installed: surface ship
Purpose: anti-air, surface detectionr
Wavelength: 150 cm
Peak Output: 5 kw
Transmitter: parallel two wire
Receiver: UN-954
Detector: RE-3
Detected: aircraft, group at 100 km, single at 70 km, surface ship (large) 20 km
Weight: 840 kg
Number Built: unknown, small number
Antennae: dipole array with mat type reflector, send and receive separate use
One source indicates only 1 set of this type built, but same source indicates it was installed on numerous ships. Type 21 first fitted to BB Ise in April 1942, Taiyo, Chuyo and Unyo in January 1943, others prior to August 1943. At least 30-40 sets built and used operationally.


Type 22

Became Operational: September 1944, see notes below
War Status: wide operational use in war
Installed: surface ships, submarines
Purpose: anti-air, surface dectection and gunnery control
Wavelength: 10 cm
Peak Output: 2 kw
Transmitter: magnetron
Receiver: crystal
Detector: n/a
Detected: aircraft, group at 35 km, single at 17 km, surface ship (large) 34.5 km
Weight: surface ships 1320 kg, submarines 2140 kg
Number Built: 300
Antennae: horn type, send and receive separate use
Type 22 fitted to Kazegumo and Makigumo in March 1942, Hamakaze in June 1942, Akigumo and Yugumo in July 1942, Kongo, Haruna and Hyuga in October 1942, Katori, Kashima and Kashii in June 43,Yamato and Musashi in October 1943, other destroyers prior to September 1944. In wide use by mid-to late 1944. Type 22 radard while not designed for gunnery control provided moderately accurate data for this purpose.


Type H-6

Became Operational: August 1942
War Status: used operationally in war
Installed: large flying boats, mid-sized attack planes
Purpose: air search and probably surface search as well
Wavelength: 200 cm
Peak Output: 3 kw
Transmitter: parallel two wire
Receiver: UN-954
Detector: n/a
Detected: aircraft, group at 100 km, single at 70 km
Weight: 110 kg
Number Built: 2000
Antennae: Yagi type, send and receive common use
This set probably did not come into commun use until 1944, and was mounted in H8K Emily flying boats, G4M2 Betty bombers, and others.
