Are you saying HQ9 is the copy of S-300 Far from it In Turkey missile competition in 2013 FD2000 a dumb down version of HQ-9 score perfect score of 5 missile 5 hit beating patriot, Aster 30 and S-300
But because pressure from US and EU and Chinese refusal to give the source , in the contract was scuttled
Not a complete copy, I'm sure there were modifications and especially hq9B must behave differently but some seem to be claiming these sams didn't have inspiration from other systems which seems dubious. hq9 has been around and been upgraded enough that I don't think it has the same performance as s-300. I don't know the details of the competition
quote from the article “Chinese sources credit Chinese engineers with developing the HQ-9 on their own.” While the so called western source is from

And supposedly they copied the Patriot too according to your source lol
And that's not possible because?

Because of no evidence, pure speculation. There has always been biases and incompetence in western sources with regards to China.

Serbia plans to acquire Chinese FK-3 air defense missile systems

POSTED ON MONDAY, 03 AUGUST 2020 10:08

According to information released by the Balkan Security Network on August 2, 2020, Serbia could acquire Chinese-made air defense missile systems called FK-3, the export version of the HQ-22. In 2019, the Serbian State Defense Company Yugoimport has published in 2019 its annual business report that mentioned an important foreign for the procurement of Chinese FK-3.

According to Chinese military sources, the FK-3 is an export of the HQ-22 long-range air defense missile system. The FK-3 system implements effective multi-target tracking and interception against a saturation attack. One fire unit, equipped with the guidance radar, provides interception against 6 targets with 12 rounds of missile. Multiple fire units, under the control of command and coordination vehicle, expand the multi-target interception to 36 targets with 72 rounds of missile.

The FK-3 weapon system can not only fulfill air defense independently but also complete missions in cooperation with other air defense systems. It has large kill airspace ranges from 5 to 100 km at an altitude from 50 to 27,000 m which super adaptive anti-jamming capacity with several anti-jamming measures.

The missile uses a radio-command and semi-active radar homing composite guidance or whole-course radio-command guidance. The vehicle launcher unit is equipped with a quadruple container-type oblique thermal launch with an automatic azimuth servo.

Is this the same system that was developed with the Italian Aspide (Aim-7 Sparrow based) missile bought during the Sino-Soviet split? Then upgraded to using PL-12 land based missiles. The one in this photo looks like it's the old PL-11 (Aspide-Sparrow copy). I remember seeing PL-12 based SAM upgrades to this system with a booster.

one request for Tam who is an expert in Radar technology.
Could you please educate and entertain a simpleton like me and tell me in a short and succinct summary what S band, C band and X bands
are? and their major applications please, if you don't mind.
thanks in advance.:)

They represent different wavelengths.

S-Band is 2Ghz to 4Ghz. In physical terms between 7.5cm to 15cm. That's how long the wave is. Your 2.1Ghz wifi belongs to this as well as some telecom bands.

C-band is 4 to 8Ghz. In physical terms it is between 7.5cm to 3.75cm. So you can see compare to S-band, its much shorter. Your midband 5G belongs to this, as well as your 5Ghz Wifi.

X-band is 8 to 12Ghz. In physical length it is between 3.75cm to 2.5cm. Compared to S-band your waves is much shorter and smaller.

In terms of radar use, S-band is frequently and most commonly used for search radars.

C-band is also used for military radars, but not as common. It is also used as a search radar.

X-band is used for military radars in particular with fire control applications, such as controlling and aiming guns, and missile homing.

The longer the wavelength, the less energy it loses when it travels across the atmosphere. It also makes a broader beam. This makes longer wavelengths suitable for volume search radars. Shorter wavelengths on the other hand, while they have a shorter range, produces a smaller and narrower beam, which makes it suitable for precise work, like gun aiming and missile homing. In metaphorical terms, longer wavelengths, larger pixels or less resolution, smaller wavelengths, smaller pixels or finer resolution.

Common practice with SAM radars, and with naval radars as well, is that you have a search radar and a fire control radar. The search radar commonly used is S-band but there are also even longer bands such as L-band and metric or A-bands such as UHF or VHF.

Then you have the secondary radar which is the fire control radar which tracks the target accurately and precisely, and is used to home in the missile or aim the gun. That is on X-band. There are radars that have shorter wavelengths, such as Ku-band, and they are used in places like CIWS.

At least this gives you some idea why a working SAM battery uses at least two kinds of radar, and also why naval warships also use this basic combination.

thank you very much for this simple but easy to understand explanation for a novice like me. Greatly appreciated.

Does anyone have HQ-22/FK-3 targeting radar data? Many sources are saying that HQ-22/FK-3 is using H-200 , but when I compare photos of H-200 with one used by HQ-22/FK-3 they look different. Also H-200 can guide 6 missiles towards 3 targets while HQ-22/FK3 targeting radar can guide 12 missiles towards 6 targets.
