Raytheon, using the new ALR-69A(V), has demonstrated a single-ship geolocation capability for an RWR receiver. The ALR-69A(V) uses four receivers, and a signal processor. Each receiver covers one quadrant of the aircraft. This is the first time any RWR unit has been able to do single-ship geolocation. Previous units were only able to give a general direction of the threat, which made it harder to decide whether to prosecute or dodge. This unit also allows targeting of the threat, while in dense signal environments.

The system also uses open architecture, COTS technology, which will keep costs down, and allow for much easier upgrades in the future. It's currently installed on the C-130H, and KC-46, and is testing on the F-16. Single-ship geolocation is a huge advantage for an RWR system. Previously it took three to four aircraft to do. If they can do it with one, that will drastically reduce the amount of time required to find, identify, and destroy threats.

Raytheon Company (NYSE: RTN) demonstrated, in a recent flight test, single-ship geolocation capability for the ALR-69A(V), a first for any radar warning receiver.

The AN/ALR-69A(V) — the world’s first all-digital radar warning receiver — enhances aircrew survivability, providing “sensors forward” situational awareness at lower costs than competing systems through simple software modifications.

“Adding single-ship geolocation capability to a radar warning receiver transforms the way pilots execute their missions,” said Paul Overstreet, ALR-69A program manager, Raytheon Space and Airborne Systems. “The ALR-69A can now assist with targeting solutions while continuing to identify threats in dense signal environments.”

Hmmm, I wonder how it does against LPI and assorted AESA's?

I wonder how it will handle multiple launch threats..

A lot better than the RWR that was on that F-16 did.

Of course if it could detect LPI sets, well that would get very interesting indeed.

And mean that security would need to be tightened up. A lot.

It's a pretty slick system. Dimly related to the trick where we can locate a single cell phone with a single small plane by mounting antennae on all four extremities and looking at the phase relationships.

SDR is inefficient, but for some things, it kicks absolute ass.

So it's basically the same as a TMA that a sub would produce but needing much more computational power. I'm guessing an increase in the sensitivity of the receivers allows them to work out the time differences between each receiver getting hit much more accurately. Add that to the fact the location of the receiver is constantly moving and it'll just be able to triangulate from there.
