Mig-25PD "Sapfir-25" Radar

It is the Iraqi one, or at least an export manual as its in English rather than Russian, I’ll tag on of the tech mods into it and ask.

it is declassed

it has been posted multiple times before on here

Thanks, I assumed so given that copies must have been captured from Iraq and probably acquired from Syria and Libya at this point, but given the lack of declassification markings on the document itself I’ll wait for a mod to green light it before I post any of the contents. Just to be on the safe side.

To my knowledge there is no issues with that document.

Awesome thanks for the response! I’ll post up the radar details soon as this match is over.

So, now it’s been given the green light: Mig-25 Radar and IRST:

You know, considering how clear this is, it’s really difficult to understand why Gaijin removed the BSV-delta H (or HMA-delta H as mentioned in the manual) mode from the Sapfir-23D-III, Sapfir-23ML and Sapfir-23MLA. And even more confusing why they did not put it in the Sapfir-25.
Well, I guess we can only hope thy will take a look at this again…

I mean this is better than on the mld where youre limited to the mti below 1500m but quite still limiting as over 3000m you can only target aircrafts over 1500m

The functionality of the Sapfir-25 are identical to those of the Sapfir-23ML (Mig-23ML). The Sapfir-23MLA (Mig-23MLA and MLD) are actually on par and even superior in certain aspects.
And if the effectiveness of the radar while in HMA-delta H depends on altitude…at high altitude is possible to see and engage targets located 5 km below you, which for the game is enough to allow it to climb and stay high without being totally blind.
Here, take a look at this below (is from the same manual and it should clarify a bit):

Sapfire-25
Sapfire-25_1

But again…that mode was removed from every Flogger’s radar and now even the Mig-25PD lacks it

Yes? Well, the RP-25M is the Sapfir-25…So, no pulse doppler. Only LD/SD via filtering the clutter at high altitude and MTI at low altitude. Same as for the Mig-23s.

Hi I made a bug report for that specific thing for the mig 23s that is currently sitting on accepted.
https://community.gaijin.net/issues/p/warthunder/i/HSeJ1FoUwY4p
I am now going to bug report the over performing mig 25 flight model

thats a wall of text not a source

i have a primary source that is not mentioning PD at all

same doc talking about the Mig-29 radar, which is PD:

and it is directly mentioning the doppler-effect

You mean mti not pd, saphire 23 and 25 never had pd

Can confirm this is true as I’ve used this exact document for my bug report for the mig23 radar

Brodie. Gimme a source that says it uses pd type filtering and not mti based filtering. The mig23 radar manual does not state it has pd based filtering bro

Check out this link where I translated the relevant pages to English for people like you.

show me any source that states explicetly that the N-003 is a Pulse Doppler radar, instead of doing mental gymnastics

to be a Pulse DOPPLER radar it has to make use of the DOPPLER effect, hence the name Pulse DOPPLER radar

Both MTI and Pulse Doppler radar rely on the principle of doppler frequency shifts. Sapfir-23ML and Sapfir-25 both used doppler filters, in practice the main difference is the pulse repetition frequency. Below 1.5km the MTI mode heavily relied on PD filters as there was no better way to filter targets against the ground, but still fell into the same radar mode for simplicity’s sake.

MTI compares the doppler shift of the pulse to the doppler shift of the ground instead of a doppler shift calculated by a computer.

RP-23ML and RP-25 were both ‘pulse doppler’ in essence, just not per the usual definition we know from western aircraft.
