Radar Return

HARM shooters love this One Weird Trick!

Eh. Damned if you do damned if you don’t.

I’ve achieved my goal of being one of those square UNKWN COM-AIR mode 3 only squawkers constant level and speed.

All airliner WX radars show up as rackets in the I/J band on the ESM. Which also happens to be the same radar band as antiship missile emitters and commercial furuno surface radars used by civil merchant ships. The I/j band is 7-17 GHz. And I think the weather radar and commercial furuno radars is around 9 GHz.

But the 3 types of radars are have different characteristics so it’s distinguishable between radar emitter types. Like we can tell when one airliner is using a different weather radar manufacturer from another airliner.

Fighter radar operates in a different frequency band from the civilian airliner weather radar.

But until I became an airline pilot I never used radar to find weather, I always tuned weather out so that I could see surface and air tracks.

Fighter radars are definitely within the band you mentioned. 9-10 GHz most commonly. More modern radars typically have a wider bandwidth to play with, but that 9-10 GHz is still the sweet spot for all-weather use, coupled with the correct PRF to give you unambiguous ranging (required for fire control/weapon guidance). So perhaps it could cause some sort of EMI? By that I mean purely noise interference. Other component could be EW/self-protect jammer usage, though that would be pretty uncommon outside of combat operations or within an approved SUA range.

Appears to be a form of EMI noise just by its look, though I doubt ECM emissions for the reasons stated. Even on an SUA range, the type and power of ECM is limited in some areas, just for the damage it can, and has in the past, caused.

Actually the 717 radar is pretty good at painting other aircraft and @NovemberEcho ‘s angst.

It is SOP now for them to climb at 200 fpm out of EWR, just to annoy him to no end.

Don’t start something, there won’t be nothing.

If you tilting down enough, you can paint surfaced submarines making the run into Pearl Harbor.

But don’t paint them more than a single sweep.

Angst and beardhair!

I remember the E175 radar painting all the parked cargo ships lounging out in the ocean just off Long Island

The Barbiejet however can only do face painting

Speaking of radar and returns, the best troll face storm I captured on WSI. Tropical storm Raymond off the coast of PVR…

Who wore it better?

A 717 is much like a 1994 Geo Metro. In the Metro you have to turn the AC off to accelerate up a hill. In the 717 you apparently have to turn off the wx radar.

Occasionally we would be bothered on guard by someone, usually the Iranians, but you just deselected guard and ignored them. It normally became a safety of flight issue if you didn’t.

At least it painted something. That radar was so terrible at painting weather.

 

[GroundPilot]

Not related to what you saw but Venezuela and San Juan center there are NOTAMs for possible GNSS/GPS jamming. A lot of military activity over there. Even for my AUA/CUR/BON flights I advise them in the remarks to check the latest safety comply for that area.

Not a huge fan of it, but I can usually use it to get what I need. That said, I do get envious when I'm on a 73 and see the resolution of that radar.

Anyway, it paints airplanes great. And ground mapping mode works really well, too. And below about 24,000', it actually gets VERY accurate at avoiding cells within the 50nm range increment, if you know how to adjust it right.

It's not the best, but it's very usable.

I’ve only flown 3 different transport category aircraft so not a huge level of experience, but it’s by far the worst radar I’ve used. I was pretty disappointed that it was substantially worse than the CRJ being a much more advanced aircraft.

The older 320 radars are absolutely god awful.
