And Iran has Synthetic Aperture Radar operational on AF or Naval assets in service for SAR duty? Really?

Why do you provide advice if you don’t know the basics?






According to the datasheet shown near the equipment and the released brochure in Arabic, the Iranian industry has developed a family of two low-weight low-consumption multi-mode radars capable of air-to-ground high-resolution imaging, day and night and in all weather conditions (including snow, rain, fog and smoke), thanks to synthetic aperture radar (SAR) modes alongside ground and maritime moving target indicator mode (GMTI/MMTI). The family comes in two models with real time processing; the more capable (150 km) and heavier (70 kg) S-813 radar with sub-metric SAR resolution imaging capabilities (1, 2 and 3 meters), has a 1-to-10 km swath width mode and a power consumption of 700 watts. The lighter one (40 kg) has a maximum range of 40 km, a SAR resolution of 1 and 2 meters, a 1-5 km swath width and a 500 watts power consumption.

If you can provide info on this contraption here deployed on an aircraft or drone, then there is no drama no?

SAR is radar not sure what fog has to do with radar based imaging.

True, that's pretty much what recreational marine radars are for, they cut through fog. My Garmin radar works great when we're out in crappy weather and is irreplicable in fog. When certain floating & moving objects can't be picked up by my GPS, I can just overlay my radar onto my mapping screen and get the best of both worlds. Can't imagine being out there without those two things. Can't imagine what they did in the old days when none of this fancy technology was available.

You can get imaging with some of the fancier & much more expensive marine radars, but I still get symbology instead which is all I need and it's absolutely critical in fog, actually. Heck, I've actually gotten humpback whales showing up on radar when they surface, and you can even see the shape with the pectoral fins and tails. But it's the best for safety reasons obviously since it basically replaces your eyes and lack of visibility, so it's less hampering especially inside busy ports where you could easily run into jetties or small piles of rocks that pop up at low tide, or a protruding dock or even a moored sailboat. That's one of the worst things, slamming into one of those because you couldn't see it from the fog.

he is a low ranking personnel in air-force something like corporal Sergent and talk many nonsense

Yes I have come to realize that more and more; not just him but a great many things I thought & hoped to be true about the country's military capabilities...

that is a navigational radar different from SAR

I literally provided info above of the exact operational details of 2 versions of SAR radar Iran produces, along with a SAR image taken by an Iranian UAV, that Iran presented at a major international arms expo to foreign buyers.

Why would Iran be selling something it doesn’t have?

You are being dense. First you make baseless claim Iran has “million of drones” then when exposed —> then when you been exposed to not knowing how SAR even works —> you claim Iran doesn’t have any SAR capability —> then when provided of several examples of SAR radars for drone and aircraft dating back to several years ago —> you ask for more pictures as if we work in the Iranian military on this website.

Just move along. You aren’t worth wasting anymore time on.

Brah, all I asked for is to show me evidence that this synthetic aperture radar is installed on an Iranian helio or any aircraft or a drone….in service for SAR. You can’t provide evidence of that no?

If yous can, I don’t got no drama…..

Foggy bottoms so far…..

SAR radar was installed on Shahed 129, but it is probably in small numbers

This is all I asked of him, but he turned into a drama queen.

Stop busting my balls, will ya! Pretty sure I made that very clear. It's the same exact technology but the applications are different. The point was concurring with what @Immortals was saying that radar is unaffected by (and made to cut through) fog in both instances, and still operates on the same principle, just for different reasons/applications, which I also listed, safety vs imagery.

Where it is installed?. SAR radar, specially movable one like shown, require a belly dielectric fairing. The only antenna shown in this picture it is just the Satcom for OTH guidance. It is much better than previous 129s Shaheds, but it is not a SAR capable UAV.

Shahed/Mohajer series are too small for a SAR capable UAV. Simply because their Rotax 912/914 haven´t enough power to fly them and feed energy required for data and TX/RX SAR modes. You need something bigger. The minimum it is a Gaza UAV, and that it is powered probably by the same engine than a Embraer Tucano.

It is probably installed in the protrusion in front of the drone.

We have samples of Shahed 129 without the protrusion in front of the drone so It doesn't have to be Satcom of OTH guidance.

 

[Immortals]

This isn’t true at all. Do you even know where Iran learned to make SAR? From captured scaneagle.



SAR is a radar and like radars they come in different capability, sizes, range, and resolution capability.

So yes you can put a SAR even on a drone as tiny as ScanEagle(Yasir). So Mohajer and S-129 can def carry SAR.

What Iran wrote about 2 SAR radars at international arms expo:

The family comes in two models with real time processing; the more capable (150 km) and heavier (70 kg) S-813 radar with sub-metric SAR resolution imaging capabilities (1, 2 and 3 meters), has a 1-to-10 km swath width mode and a power consumption of 700 watts. The lighter one (40 kg) has a maximum range of 40 km, a SAR resolution of 1 and 2 meters, a 1-5 km swath width and a 500 watts power consumption.


So can you tell me why you think Rotax engine cannot power a battery that can provide 500-700 watts of power?

Iran also has Inverse SAR (ISAR) so when the commander made the comment “they were in Indian Ocean” he was likely talking about drones with ISAR capability which excel at finding moving maritime targets against the noise of ocean background.

 

[Flotilla]

AFAIK this is the only evidence of a dielectric fairing belly with a possible SAR radar in a S129.


This fairing it is similar in shape and size to those already posted. And news were published in Jane´s.

New payload seen on Iranian Shahed-129 UAV

At least one of the Shahed-129 unmanned aerial vehicles (UAVs) operated by Iran's Islamic Revolution Guard Corps (IRGC) has been fitted with a previously unseen sensor,...

www.janes.com

Also, there is some images with a smaller belly fairing that is probably capable of carrying a small SAR radar as you have described.



But, or you design a new UAV with integrated SAR radar like Scan Eagle (and even you can see a dielectric panel in the fuselage of the UAV or you need to modify a already designed UAV to fit a SAR radar.



You can see rear the gimballed camera at the bow the dielectric pannel where it is carrying the SAR radar.

None of these features are visible in the 99,9% of Shahed or Mohajer family drones. That it is the reason that makes me think that SAR radars are really not operative in IRGC/Artesh UAVs.

Hope I am wrong.

 

[Immortals]

I agree with you the number of SAR drones is likely low.

The ones that do have SAR likely also have ISAR capability and deployed to the near PG coast or waters (support ships). But it is absurd that there wasn’t 1-2 drones available for emergency situations like losing your president. Even I was Suprised.

Overall, There isn’t a whole lot of value add for Iranian drones to have SAR at current moment since they don’t have satcom or heavy data uplink at long distances. SAR is great for recon and there is only so much recon iran can do around its own borders.

More suitable for Western imperialist powers that operate all around the globe.
