TR Naval Programs

[uçuyorum]

X-band CFR yes, i have stated this earlier too and that's what many X-band MFR do. However we are speaking about an air-defence destroyer here and better spare those modules for keeping an eye on the sky - horizon - near surface than pulsing a data for each missile. That was the purpose of AYR.

But it is an AESA radar so you can allocate a fixed or dynamic ratio of modules for scan vs illumination and have an overall larger multi purpose radar than have multiple small ones. The rest is programming.

A missile engagement takes 3-5 minutes, so we are talking about allocating certain modules on different sides for multiple data link beams during that time, while continuing to track the target if it is within the CFR's range, continuing to track the horizon, and being ready for gun engagements? Why not.

I don't get the big deal, processing power and software should be able to handle it.

Not to say its trivial, but that it has precedence.

If you are simultaneously doing weapon quality track, volume search & creating data link beam, lesser and lesser T/R modules you will get to allocate for each function, and your range/resolution will gradually get worse.

But looks like UMR's T/R module numbers way higher than earlier...

S Band UMR/ERALP is not only used for long range detection but also guidence of Siper system. Mr. Sünnetçi mentioned this in his last LinkedIn post

One of the Siper launches was done without ÇFAKR radar to test this capability but I'm surprised they decided to drop the X-Band. The results must be very satisfactory and the quality of the track in S-Band must be comparable to X-band.

The X-band gives less range but more resolution because it has a shorter wavelength
The S-band gives more range but less resolution because it has a longer wavelength, physics dictates that.
S-Band is somewhat of a sweet spot. You can still get weapons-grade track in the S-band but nowhere near the quality in the X-band. If you go further down to the L-band there is no way to get weapons-grade track data. Aselsan must have developed a way to get good-quality track data in S-band. It should be good enough that the engineering trade-off decision leaned towards dropping off the X-band. The datalink function is easy because the transferred data is not huge and in fact very small compared to UAVs.

If we have performance of latest AN-SPY 6 i am not really minding it, we can even put only one rotating AN-SPY 6 with 25+ RMA i would accept it as an air-defence destroyer. If we have auxillary (alternative) sensor capability of USN we may sail this without any fixed face AESA but MAR-D and CENK-S radars even. Do not refer to SPY 1 as it is outdated and intended to be phased out (though still performing remarkable well even against small aerial threats or BMs at the same time).

Greece is wanting to get american constellation class frigates for their navy . although the ship has spy-6v3 with 9 rma, I wonder how useful will it be for them...

Just how capable is the spy-6v3 compared to spy-6v4 Or CAFRAD radar?

From this phrase get the immersion that they changed some stuff with the UMR

You seriously need to provide a translation bro.

You seriously need to provide a translation bro.

Shortly: With technological advancements, the S band radars that were only previously meant for early warning against air breathing targets will now be used also for guidance of anti air missiles. Furthermore there will only be a single x band radar against surface targets. The radars will be distributed around ship like arleigh burkes.

2D means 2 axis AESA scan, not "2D" in dimensions. Also, 4 face AESA is not mandatory for surface scan, since surface threats are less likely to travel at high speeds. Instead a rotating AESA with 30/60 RPM modes will serve the duty.

Too much information ..
I barely understand

So Türkish AESA radars are not 2 axis?
Cenk-S and MAR-D?

Here is how the dual axis scan looks like! I would love to see how our radars working and emitting signals

Allah rızası için biri iki AESA radarın farkını çocuga anlatır gibi anlatsın.

Neden bize iki tane radar paneli lazım?
O zaman Cenk-S veya mar-D surface tarama yapamıyor? Tüm AESAlar multibeam ama en son teknoloji AESAlar dual axes multi beam.

 

[TheInsider]

There is also another thing I mentioned in the past. Dual-band T/R modules. Aselsan has been working on dual-band modules. What if Aselsan managed to produce a T/R module or a building block that can work in both S-band and X-band with sufficient performance?

A little more about MURAD
MURAD 1000+ GaN T/R

GaN T/R Module
PAE(Power Added Efficiency) : Rumors start from %37 and reach as high as %54
20W nominal 30W peak output power per module (20kW power-30kW peak power for radar plus several kW for accessories like LRUs etc.)
Multilayer LTCC packaging (Low-Temperature Co-fired Ceramic)
SIGE (Silicon-Germanium) multifunction BICMOS IC/Core Chip (either on 130 or 150nm/0.13-0.15μm)
GaN MMIC (likely on 150nm 0.15μm)
Digital beamforming+cognitive radar algorithms.
Specially designed ethylene glycol+water liquid cooling system with microchannels.

Radar part of the BURFIS
2000+ GaN T/R module

It is rumored that the complete RF integrated suite(BURFIS) might have a peak power of more than 100kW.
Another rumor is that radar will have dual-band capability (S and X band) and will be able to detect stealth targets over 100km.

Another piece of news is that Aselsan is working on an L Band very long-range land-based radar.

I think this was spot on. We are onto something here. I posted this on November 16, 2022.

@TheInsider Will ERIS/ERALP get the same update as UMR? And will it be able to guide SIPER Block I & ii?

EIRS already did a test shot with Siper without ÇFAKR (and did another with ÇFAKR). This seems suspicious.

2 radars are for better coverage, not dimensions

 

[UkroTurk]

So, I-class frigates urge at least fixed 4 compact X-Band plates for surface scan against cruise missiles.

 

[Aqerdf]

To me, i still would want that third radar group. For conduct extreme level of jamming.

Some Arleigh Burke's have these afaik. Those latest ugly looking ones ? After the mod. ?

The SEWIP block III upgrade program. Fat fucks.
