Re: PLAN Type 052 Class Destroyer
Does anyone have any relatively solid/factual information on the electronic sub-systems of 052C/D series? Most of the stuff I have read about are mere guesses and approximations. For example, we know they have large modern looking AESA radars based on its appearance, but we don't know anything about the output, sensitivity or noise reduction abilities. Another area I'm really interested in is its software structure and ability. Are those macro-systems built on Sun? Linux? Or else? In terms of data links, Wikipedia's sources say 052C's is equivalent to Link 11 and D is to 16.
But after all, none of them have reliable sources to back it up. I understand it's hard to get 100% factual information on these classified contents, but it is possible to have credible and educated deductions using sources like published research articles and military news report. So far, most of what I have read are just guesses and beliefs of military fans.
If anyone has anything good, please share it.
Thanks
Common knowledge is the AEGIS system operates in S-band, from about 3.1 to 3.5 GHz. Thee are also three sub-bands, FL, FC, and FH, each 40 MHz wide measuring antenna gain. The latest updates possibly in the 160 MHz at broadside, and 120 MHz at a 60 degrees scan angle.
The Aegis system’s bandwidth was also apparently subsequently increased, perhaps up to its maximum frequency extent of 400 MHz and can operate in the wideband mode as well. The much bigger arrays in the Delta means only one thing and that is an increase in the elements or subarrays.
The latest SPY-1D(V) 'reportedly has an average transmitter power of at least 77 kW, based on a 58 kW average transmitter power for the 1B/D version. Peak power output is probably in the 6-8 MW range for the SPY 1D.
I would say the 052D is probably in the 4-6 MW range equivalent to the SPY 1B arrays.
The only public numerical figure on Aegis detection range against a specific target is that the SPY-1D “can track golf ball-sized targets at ranges in excess of 165 kilometers.”. A golf ball-size (1.68 inches diameter) sphere corresponds to radar cross section of about 0.0025 m2 at 3.3 GHz.
Those are all estimations and I assume the AESA on the O52 is relatively similar at least to the SPY 1B arrays. Anything else would be highly classified and will get you a visit from men in dark sunglasses.
