Yea and now translate the rest
Translate what? It just talks about reducing pilot workload by minimising the amount of information presented to the pilot.
“Cooperation” of the separate sensors only refers to ruling out deviations.
I mean c’mon, how the algorithm for PIRATE functions is publicly available. At no time does it actually mention using other sensors to filter out false positives - instead this is done by the pilot.

I dunno, but I’m blaming the English, they’re easy to blame.

Seems to be a common theme among modern aircraft. F-22 program manager said that the AN/ALR-94 (ECM suite, like SPECTRA), was the most technically complex piece of equipment on the aircraft.
Of course, they are also among the most classified

Maybe its a Language Barrier thing.
But for me it talks about the Sensor working with each other.
If for example the Radar cant see a target but the Pirate can maybe because its a Stealth plane.
the Pirate gives the Radar the location so it knows were to look.
Atleast thats what i get from it.
And then it gets send as one Information package to the Pilot yes.
Rafale wrong medium speed acceleration

Well, the output of results from PIRATE would be delivered to the pilot and weapons system which could cue the radar to look in a certain direction. But it wouldn’t be able to improve the accuracy of the tracking in any way.
For the Rafale, it will cross-reference the seperate tracks from the IRST and radar prior to delivering the more detailed information to the pilot and weapons system.
In the case of the Rafale, this will result in shorter reaction time, improved accuracy, robustness to countermeasures, masking and environmental conditions.
This is especially not possible on the Eurofighter since the only sensor that can provide accurate localisation data is the radar.

Weren’t there discussions in this thread a while back establishing pirate can give “good enough” positional information? Radar generally lacks the limitations to my understanding, but pirate can perform adequately under some circumstances from what I remember reading?
It is entirely possibly I’m misremembering though, I usually only peruse this thread when I’m mostly asleep. Makes dealing with certain individuals easier.
Since it’s IR (iirc), I don’t think Pirate can see through clouds or any weather really. A clear day is probably the circumstances it’s talking about
It depends on your definition of “good enough”. According to the UK’s Defence Research Agency, the kinematic ranging algorithm only guarantees an accuracy within 20% for ranges up to 100km.
Thales themselves also state that a laser rangefinder is necessary for accurate ranging:

Right, seems remembering “Good enough” is a bit of a stretch

You could miss a nuke with accuracy within 20% at 100km lol

PIRATE is capable of accurately tracking targets, and being commanded to do so by external sensors such as the radar or datalink:
You mean like this?

PIRATE can provide target bearing, sure. Not accurate target tracking.
The Eurofighter cannot compare and combine seperate target tracks like on the Rafale.
One of the sources you cite is literally from the same source I have cited above which states a laser rangefinder is necessary for accurate ranging.

If there is any adverse weather or fogs/clouds does this completely stop PIRATE from detection of stuff past them?
@Mulatu_Astatke can Rafale IRST see through weather or is it just a hard limit on all IRST?
Interesting are you able to share the relevant section of that document?
That document is from 2003, PIRATE wasn’t even ready for IOC until 2008, and received a number of improvements after introduction to service. Passive ranging was one of the later functions to be fully developed.
What do you mean by this?

Performance would become limited for any infrared sensor. But different wavebands perform better or worse in different conditions.
PIRATE only uses the LWIR band which when used alone is disadvantageous for air-to-air operations.
Rafale uses both MWIR and LWIR which performs better across more difficult and diverse conditions.

Passive ranging algorithm was developed in the early 1990s, since then none of the hardware changed substantially.
Besides, how do you suppose passive ranging accurately measures the range? Kinematic ranging is just a fancy term for ‘stadiametric rangefinding’. I don’t think any modern day sensor except maybe a space telescope fitted to a plane could provide accurate tracking at a distance of ~100km due to the required resolution.
Well, I say IRST but it would be more accurate to say ‘TV channel + laser rangefinder’ - the terms are generally used interchangeably for OSF.
In sim, auto MAWS looks like it work a lot more better
When selecting a coordinate on the map, the cross that previously displayed correctly on the radar MFD is no longer showing properly.
