Furke 2 is an air and sea search radar, it doesn't do targeting. On Project 20380, another radar does the targeting, which is the Monument radar. This radar is hidden inside the tower mast underneath the Furke. with the mast acting as a radome. While Furke is a revolving phase array, Monument is a mechanical antenna, not unlike the MR36A in design with a curved dish and horn, not a fancy electronic scanning array. Furke is an S band rand, but Monument is likely to be an X band. (The radar on top of the bridge is the Ratep Puma radar for gun fire control, so we can disregard that).

Export versions proposed for the ship has Positiv radar on the top, and Garpun inside the mast radome. Both of these are not new designs, and there are two versions for the Positiv, one for frigate and destroyers, the other for corvette and missile boats.

250km isn't fighter or plane targets. Rather Super Refraction sounds to me like Surface Wave Propagation, which is a way of detecting and targeting ships beyond the horizon. Likewise the same for the Chinese radars, they only use a different term for it, like MOTH or Microwave Over The Horizon. The 250km is all about searching ships beyond the horizon.

I do feel now with greater probability, that the radar on the Type 056 is Type 362 which is X band and not Type 360 which is S band. The reason why Furke and Type 360 can do >250km OTH, is because they are S band. Type 362 however is an X-band, which doesn't propagate as far, so its OTH range is 120km.

The reason why I think 056 uses Type 362 is that Type 360 (LR60) requires a separate radar for the SSM, and in those ships that do have Type 360, there is the Type 352 radar for older boats, and the Type 366 (Bandstand, MR331, Mineral ME) on newer ones.

If fitted with Type 360, Type 056 lacks any other radar for SSM, as the only other radar is the Type 347G for the gun control. The Type 366, which is housed on a large white dome usually above the bridge that has become a typical feature in many Chinese warships, is certainly not in the Type 056. Type 022, 056 and Type 055 are the only current modern naval surface combatants of the PLAN that does not have the Type 366.

Type 362 (MR36A) does have OTH targeting and SSM support, and provides this for the Type 022 and so its a pretty good bet that's the one on the Type 056, as it would leave the ship self sufficient with all its radar requirements except for gunnery control, which is filled with the Type 347G. There is no question the Type 055 has a brand new radar to fill this purpose, and quite likely, much too large for the Type 056, not to mention its power requirements.

what's also interesting is what they call
Passive channel
inside:

Passive channel means the radar is not emitting, but is listening in on the target's ship's own radar. Type 366 and Bandstand should have those capabilities as well, and I believe the Type 362 does too.

for me it's funny how certain circles invest in 'stealth at sea' while even a Corvette might be able to detect an emitting radar from a hundred miles away

Ships, if not entire fleets, also drill about radar and radio silence.

Historically I checked for the ships that use the Type 360 family.

The Type 052 (DDG 112, 113) like the Harbin, has Type 360S (S for S band) in the top mast and the first and original version of the Type 362 in the second mast. This gives the ship a dual S and X band capability. A Type 344 provides for fire control both for the main gun and the SSMs. An updated version of the Type 362 was developed for the Type 022, and this may have been updated further for the Type 056.

The Type 052 upgrade had the Type 360S replaced by the Type 363S, which is also S band, and the Type 362 on the aft mast is replaced by Type 364 (SR64, Seagull C, C for C band), for a C and S dual band combination. Which is why the aft mast now has a rear white bulb.

Type 363 and Type 364 combination first appeared in the Type 054 frigate. Type 364 seems quite popular with the PLAN, as this is the aft radar you see on every Type 054A, the top radar you see on every Type 052C/D, and this was added to the refits of the Type 052, the Type 051B and even the Sovremenny.

If compared to the Type 362, detection of 2m2 object is raised from 42km to 75km on the Type 364. Type 363 goes even further with a detection range of 2m2 at 60 nautical miles or 110km. Maximum OTH range of Type 364 is about 300km, but I cannot find any figure for the Type 363 but its likely to extend even further.

While Type 363 sounds much better when it comes to range, it seems to be a pure search and early warning radar only on the ships it was used on. The Type 364 however appears able to queue Type 730/1130 guns and provide firing information for ASMs. I do think the Type 360S is able to direct guns, as they do on the Jiangweis, the Type 363 could also, just that the Type 363 happened to be used in conjunction with the Type 364, as in the Type 054 frigate, and the 364 was assigned with the rear gun duties.

I think both radars can be a little to no cost off the shelf upgrade to the Type 056 to replace Type 360S or 362, though I suspect the X band Type 362 might be better in resolving against small boats at closer ranges. But for air defense Type 363 or 364 would give a bit more of an edge in detecting LO objects at a longer range to provide more adequate warning and reaction time. All these Type 360 family of radars have similarly shaped antennas --- hence the frequent confusion with this family --- so if an upgrade indeed happened, it would be hard to discern visually, like if the Type 364 is used without its bulb cover. Between the Type 363 vs the 364, I would lean more on using the 364, as this seems to be very popular with the PLAN, so there must be something more about it than the little information we have out there.

Type 364 without the bulb radome.

I also look closely at the Bangladesh C13B corvettes and their radars are different from the Type 056 as they appear more spread out and has more of a lattice structure at the back, while the Type 056 radar has this prominent tic tac toe ribs, and the array is a bit more curved in. I am likely to think the C13B has the actual Type 360S or its successor, the Type 363, while the Type 056 uses a modified Type 362 or 364.
