@Yasar_TR what is pulse-Doppler radars Doppler shift issue which may cause problems with tracking targets moving perpendicularly? sure have little idea but if possible need to hear it from you as well .....thanks

was just reading an article about SU 24 case in Syria

I am no radar expert. My radar knowledge is somewhat rudimentary. An expert on radars may explain it better. Somebody here had mentioned @Nutuk ?? Also @TheInsider seems to be well versed on radars.
What I know is that almost all radars work with Pulse-Doppler Shifting.
Radars send a pulse to target and measure the time it comes back in. This is a vital measurement.
But if the transmitter sending it is moving or the target receiving it is moving, then the waves coming back can be compressed or their wavelengths can be longer depending on the target coming closer or farther.
Also if the target has a close background that reflects signals back then it becomes difficult to read the position of the target. But through relative velocity of the signals, their position can be differentiated by Doppler Shifting techniques.
By measuring the Doppler rate, the radar becomes able to measure the relative velocity of all objects‘ returning echoes – whether planes, vehicles, or ground features - . Doppler filtering can be used to discriminate between objects moving at different relative velocities.

But if a target is moving perpendicularly, Doppler Shifting doesn’t work as the motion is tangential to wave motion. This gives zero value of Doppler Shift. It may appear as static clutter.
To overcome this the radars use certain techniques that can overcome the non existent signal of perpendicularly moving targets. A parallel processing channel radar and linear frequency modulated radar can detect zero Doppler Shift targets. How they work is beyond me. Like I said above an expert on radars should answer this.

Hisar-D will not be quad packed, this is a huge failure. 16 vls with HISAR-D or 8 Siper and 8 Hisar?

Nothing new here roketsan said they’re developing a new missile for that GM-1 may use similar components but that’s just a feeling

My guess would be that hisar d is going to be the cheapest medium range option for ad would make sense for adkg and for tf2000. I doubt navy would be satisfied with single pack hisar d

Hisar D can not be a long term missile because its slow around 2 mach,thats why quad pack unnecessary.İts difficult to respond multiple anti ship missiles and also there is a trend for süpersonic even hypersonic missiles.Roketsan is on the right way in terms of Midlas to adapt for siper and atmaca missiles,so you can make two seperate 16 cell midlas on istif class total 32 cell, this gives more flexible mission profiles,and means you can fire multiple missles more quickly.

Wher do you want to put another vls on the ship?

What source do you have regarding Hisar class missiles’ speeds?

This is a closely guarded secret, and never been openly discussed. When they were being developed it was mentioned that they were 3+ Mach missiles. (See below article.)
Some article somewhere may have mentioned 2mach speed and it stuck. Nothing concrete ever been declared about their speeds.
These are missiles with dual pulse motors. Similarly powered missiles reach speeds in excess of 3.5 Mach and more. In fact some like sky-ceptor may reach 5.5 Mach.

There were Roeketsan data sheets from a recent expo showing HISAR A+ having a speed of Mach 2.5 and HISAR O+ having a speed of Mach 3.5. I imagine HISAR O RF will have similar speed to that of HISAR O+.

In fact some like sea-ceptor may reach 5.5 Mach.

Very much doubtfull. Any source for that?

My bad. Should have read the post again . It is a mistake.

Skyceptor missile produced by Raytheon not seaceptor



Can you share that data sheet please?
Because none of the Roketsan paperwork states any speed related to these missiles. Technically the dual pulse engines should give higher speeds than a dual thrust version. Especially in terminal phase where it matters.

New SOM-J test. Peculiar.

What's peculiar about it?
It's tilted 90 degrees on its axis, even though it's on a level downward flight without any visible maneuvering in the last leg. They are probably studying further flight envelopes.

“In the firing test, where challenging maneuvers to evade defense and radar systems and very low-altitude flight capabilities were demonstrated, #SOMJ proved itself”

this explains it I guess
