Ukrainian Anti-Stealth Radar Sold to Iraq Discovered in Ethiopia (Saddam paid $100 mil for 3 units)

Receive only. The emitter is located elsewhere. Also looks for other emissions in the RF bands such as those generated by ground avoidance radar.

[TopQuark]

I wonder what a "passive" radar is?... The one that detects and tract but has not capability to point anti-aircraft weapns.

[dglang]

It doesn't emit any radar sugnal of its own, but monitors for disturbances of normal radiations, especially cell phone transmissions which break up when any plane causes their signals to be deflected. A stealth plane like any other plane will cause a disruption in signal if the signal happens to hit it. That disruption can be detected. That disruption or disturbance can be either a sudden increase or decrease in signal strength.

Anything that moves leaves a wake.

As a/c fly, moving air creates static on the vehicle.

That's why it's real smart to use grounding cables on a just-landed a/c....especially if refueling.

If you figure out how to detect the static wake, air wake, heat wake..............poof!

So angular refraction like the F117 vehicle might not keep ya' stealthy.

Maybe that means that F117 era vehicles will soon show up on the used warbird a/c auctions? Cool!

[SMEDLEYBUTLER]

You assume incorrectly.

Not so fast. The B-2 is equipped with the AN/APQ-181 which has both TA and TF modes. So yes, it is equipped with radar.

[Poohbah]

Yeah, it just doesn't USE the damn thing.

Cell Phone Towers Expose Stealth Aircraft 'Passive radar' can spot Air Force's B-2, F-117A

That's the one I remember reading about during the Kosovo war. I suppose it's feasible, although it seems to me it would take some mighty sensitive receivers to detect and track a stealth aircraft through the RF "disturbance" it supposedly causes. Do the bad guys have such a "Skunk Works" capable of exploiting this? Or, did somebody on our side sell the technology to them? Or, was it just a lucky hit when that F-117 went down? I only know what I read.

[Andy from Beaverton]

The radar used to shoot down the F-117 was the Czech-made TAMARA anti-stealth radar. I know two or three other F-117's were shot up so badly they were taken out of the lineup.

This is certainly not good news, if true. Methinks another up-tick in ECM's will be in the works. The wheels are turning at Rome Labs....

[VaBthang4]

If I am not mistaken the only thing this technology does is watch for the tell tale signs of an aircraft coming in and out of a certain area.

It cannot lock onto or direct fire, it watches for tactics [ie flight paths, flight habits] then after a couple of days of watching for habits....you move a hunter killer team into the flight path or setup AAA batteries and then wait for the aircraft to fly by....then you open up on it.

The shoot down was the Air Forces fault. They did not change their habits and flight paths...the chinese saw this and directed the AAA to the area.

This is what brought down the stealth.

Tactics will for all practical purposes render this thing usless past being a trip wire.

Probably bi-static. With bi-static radar the transmitter and the receiver unit are separated. They have anti stealth characteristics in that stealth aircraft can't redirect a signal away from the receiver.

Not good news.

[Diddle E. Squat]

Baby Milk Plant radar.

I never watch Brokaw, but today I was tired of hearing Hannity and Colmes talk about Blakely, so I had on CNBC. Brokaw was in Bagdad, and guess what, no starving Iraquis, plenty of food and commerce, especially Western goods...people were friendly to Americans. No problems in Bagdad, anyway. So much for the starving people in Iraq, down goes another fairytale. As told by a liberal newsman.

[lwoodham]

I thought that the trick to detect stealthy aircraft was to have both active and passive radars with the active one located away from the passive ones by some appreciable distance. The 2 sites would have to be timing related. The active radar would transmit and the stealthy aircraft would reflect the signal at oblique angles but not straight back at the active radar site. The passive radar receiver would have a fair chance of detecting some of the reflected energy. Multiple receivers may allow pinpointing the location of the target by triangulation. My 2 cents worth!

[Rebelbase]

China is still pissed about that...GOOD!

[Blood of Tyrants]

So China supplied some passive radar to the Serbs for a field test on our stealth aircraft?

That's my pet theory.

[Blood of Tyrants]

No way, dude. The military took spy pictures DAILY to determine targets. The embassy was targeted purposely. If not, why blindly drop a single bomb? Why not level the whole aera? What was supposed to be there worthy of bombing anyway? Old maps show it as an empty lot. Why bomb an empty lot?

[ScreamingFist]

"I wonder what a "passive" radar is?..."

A system that emits no radiation is passive, in this case, the "radar" is a receiver that detects emmissions (read that as radar transmissions) from the aircraft. Not exactly high tech by a long shot, since any aircraft on a stealth run would go into a Low Probability of Intercept mode and keep radio and radar emmissions to a minimum.
