Turkey successfully tests HISAR-A air defence system

[Kamil_baku]

Semi active guided missiles require continuous illumination and missile follows the radio waves reflected by target so Target’s EW can easily detect those missiles with “lock” signal.

If the missile is Rf guided active homing, then The missile’s radar emits the continuous waves to target and same missile receives the reflected waves from target. Continuous illumination is not needed in those missiles but RWR can detect them with the waves emited by missile itself.

If the missile is Command guided, the search radar track the target and a seperate radar track the missile itself. The fire control computer calculates the interception point in accordance to datas received by both radars. The missile is steered to intercept with target by same seperate radar. This is the most sneaky way of striking high value targets because The target will realize a radar (If not working on passive mode) tracking itself but never know a missile approaching to him. That is the method developed to overcome RWR but, The ultraviolet signatures of coming missile can be detected by MWR. The latest generation missiles have smokeless propulsion with less heating signature on terminal phase with stopping rocket motor not to burn fuel in this phase so the pilot will just have a few second to realize He is going to be wasted in a short time. Hisar-IIR is the most effective way of killing enemy aircrafts thanks to command-guided method on midcourse and IIR guidance ın terminal phase but IIR sensors bring some limitations on surface to air missiles. They are good but not perfect on naval applications because of being effected by bad weather conditions and foggy environment. Same for land based variants on regions having rainy and foggy climate conditions. Their ranges are not long enough against active homing missiles so Hisar-O will be revealed in two different variant. IIR and Rf.

Great one!!
another problem with those missiles that need illumination radar, those radars will be the first target as soon as they lock on... once you hit the radar with anti radiation missiles like harpy fast, you also kill the missiles itself..

As you said when the fire control radar locked ,radar warning system work but not with search radar

RWR systems identify search, interception, lock and advanced ones launch process.

But the Hisar A system must use a searching rather whereas its missile use IIR guidance. Therefor the system is under risk anyway because of its searching radar. The missile also uses datalink with the command post. If command post lost radar engagement , the missile also would lose datalink.

Data Link is totally different that active radar,
active radar is like turning on your lights at night to see and you will be seen too, but data link is communication and more like looking through night vision..

Congratulation

 

[Faith_of_the_Fallen]

İs there any counter measure sytem to engage at the terminal phase of the IIR imissiles other than maneoveur of the plane?

There exist gimballed systems, which tries to saturate the detectors of IIR seekers; therefore cluttering the image and hampering the quality of object recognition of image process algorithms.

intresting example. also RF guidance is like some one looks the target and tells you it's proximity so you can approach it and use your IRR seeker.

that's a risk all the ground radars take. also it does not mean the fighter planes can just take the air defence as they see it. usually ground radars have larger search and interception range and also they are heavily protected. at the end every weapon humans make has some flaws whether it's air defence or fighter jet.

We are speaking about the radar of Hisar A systems which is also used to correct to course of missile via datalink.

Absolutely they are different but via datalink being send which info? Where does the info come from?
Without a radar, a datalink would send just empty signals

if i'm not wrong you said that you're worried about the fact that fighters would notice your radar presence. well i said before that as air defence systems unlike airborne radars have access to more power and unlike fighters have no limit on antennas size, have bigger ranges. but if youre worried about jamming on data link that is unlikely because most of air borne jammers work in s-x band not radio frequencies.

I meant the Hisar system. Another question I suspect if Hisar's missiles could use the data from another radars via datalink device. I think long distance from another airborne radar to the missiles is the big issue.

missile itself no but ground unit can.

do you mean anti radar missiles??

Nope.

İt makes sense
