i thought i would look up the phoon…
One of the fundamental sensors available to a modern fighter is its radar. However the use of such a system also puts an aircraft at risk since, as an active system it emits electromagnetic radiation. The DASS is equipped with Radar Warning Receivers (RWRs) designed to detect such emissions. The particular units used are Super Heterodyne (SuperHet) based wide-band receivers and are located in the port side pod (both front and rear) and within the aircraft’s fuselage giving full 360° coverage in azimuth (elevation coverage is currently unknown).
These units are combined with on-board processing systems enabling not only a bearing to be determined but also the likely type of radar (and thus the platform it is deployed on). This is achieved using a stored database of radar signatures forming part of the ESM, Electronic Support Measures suite. Through the use of high speed digital signal processing the ESM will attempt to map the detected emission to its database. One of the weaknesses of current (and more so older) RWR systems is a difficulty in countering Low Probability of Intercept (LPI) enabled emissions. These use various techniques to try and hide the emitted signal. Although it is unclear whether the DASS RWRs possess a capability to detect and classify such emissions it is known the Marconi (now BAE Systems) have been working hard in this area for some time.

it seems every man and his dog has directional rwr
could it be that rafales acknowledged poor radar performance is leading the reason the french are trying to discount the need for it
perhaps when it gets its aesa, this will fade
especially since TMor told me that only f3 has LOAL capability mica
so up till now, its just been a story anyway

well has the defense force put out a statement confirming or denouncing the news article

its not my circle, the only data it would provide is given osf would see 40k, its between 40-150k on x bearing
both planes shift from co-ords and another reading is taken
now the data is 40-150 on y bearing
this cant tell you where in the y bearing it is as you suggest
it shifted its position from when the x reading was taken and so there is now no relevant data to give a fix on where on the y bearing it is
if it was a constant signal strength out put, the received rwr on x and y would tell you if its getting closer or further away in the 40-150k bearing
if you were comparing x,y of a sam site, at the intersection of the bearing of x and y is the sam site, it gives a positional fix

that sort of worked on ships for ships during ww 2
it will work for sam sites and such
but the air target is also moving fast and when you do get your best estimate the area would be large, it still wouldnt give you a firing solution at 60k

No.

You asked for a link explaining how passive ranging can be done (since you stated it’s impossible multiple times). Now that such link has been provided you’re once again behaving like a child to save face.

I suggest you grow up, there is nothing wrong with admitting one’s mistakes.

you missed this part of my post
and we are talking a single plane, not multiple bngs giving a fix

heck, i am happy to be wrong, it would be an advantage for our old hornets that have directional rwr too, to fire our aim-120 at 100k passively

so some experimental ranging is your proof of life for the rafale’s rwr
to the statements that the rafale can passivly fire max range mica from on-board sensors
i am asking how

mate, it has no names, no quoting a report. the proof is a ‘news source’
was it really worth posting ?
at this stage the fa-18 production line shuts down in 2013

Indeed, that’s not the point. The point is that with accurate enough RWR and some smart logic it is possible to achieve a complete firing solution (i.e. know the target position, heading & speed) passively. Quality of the solution would depend heavily on the RWR angular accuracy which is of course classified (it’s “better than 1°” but no one knows how much better).
A few years ago, AdlA officials wouldn’t even confirm that SPECTRA data could be fused with weapon systems. It’s the most sensitive part of the plane.

so we agree it isnt unique to the rafale

can you give me a link to where it is stated that directional rwr will provide accurate data for a 60k a2a launch, as i said, i havent see it
