34.4 GHz radar frequency

**justonekiss** · 08-01-2005, 01:59 PM

Anybody knows what US radar device is using 34.4 GHz radar frequency?
I saw many reports regarding tests made with this frequency, but didn't found the name of the device.

thanks

In the US? Nothing that I know of.
The reports could have been a misprint, or it could possibly be a Stalker drifted off freq (normally 34.7 GHz).

these are only few of the articles on the internet including words about this frequency:

www.radartest.com
With this the user can instruct the detector to listen for one or as many all five of the most widely used Ka-band frequencies: 33.8, 34.36, 34.4, 34.7 and 35.5 Gigahertz. Four of these are used by U.S.-spec radar models that, as a group, constitute the fastest-growing threat on the road today.

34.4 GHz Ka did not jam at all from 1500 feet to the gun.

it must be some guns with this frequency

To be more accurate, it should be mobile photo radar, 34.3Ghz (-/+ .2Ghz), so 34.4 falls into that range.

In this article, this is said in reference to the BEL 975R.

However, if you Look at the BEL 975r User's Manual, it only says you can select 33.8, 34.36, 34.7, 35.5 GHz, there is no mention of a fifth frequency, 34.4, as mentioned in the radartest article. Likely a misprint.

This is in reference to an SML test of the Scorpion active radar jammer.

I am sure they meant to test it against the 3 main freqs used in the US: 33.8 MPH, ~35.5 Kustom/Decatur, and 34.7 Stalker. They list 33.8 and 35.5, but no Stalker at 34.7 Ghz?
So, this is likely a misprint as well.

I'm not saying that there aren't any guns specifically operating on 34.4 GHz, but I havent seen any clear evidence that there are. If you receive anything there, it is probably either a drifted Stalker, photo radar, or a harmonic from another detector.
