The AWG-9 knows the closure by knowing what it isn't...

That sounds file becomes a Lovecraftian nightmare for me.  It drives the sanity from my soul. Lol.

I miss the smiling reactions.......alas, in their absence, here is championship cup!

As draconus says, nothing else will change. If you read target rate vs MLC it will be observed target closure rate but it always was. All the displays will be the same, this was a misunderstanding that only affected the filters.

 

The Vc switch is not a DDD scale switch, it purely controls the Vc bug on the DDD when in the STT modes. The only thing controlling scale on the DDD is the target aspect switch and then it just moves the location of the MLC around so the total scale on the DDD from top to bottom will always be 2400 knots.

Well then I'm confused here. Why allow the Vc scale in STT to go that high or low when the radar is, from what you guys have modeled, cannot physically detect or track something of those speeds?

Because in PD-STT the doppler filters aren't used so it doesn't have this limitation. Not sure if it currently is like that live but it will be for sure when the fix for the filters are out.

do you mean p-stt?

Does this mean that the ground clutter filter was also working incorrectly?

No, PD-STT. The doppler filters are used in the search modes to generate the synthetic display blocks for the different rates on the DDD. In PD-STT those aren't used, then the velocity tracker is used instead.

im confused. i thought pd did use the filters, i thought thats what pd meant, pulse with doppler filters applied??

Yes, PDS, RWS and TWS use them to slot the returns into doppler filter slots for display on the DDD. In the doppler search modes raw radar video isn't useful for display on the DDD unlike in pulse search. So each return is sorted into a specific doppler filter slot which then generates a syntethic block return at the rate corresponding to that filter.

 

The presence of those filters is not what makes the radar modes a doppler mode but rather how the returns generate information on the DDD (and for track files). In PD-STT the filters aren't used as you only have one target which is tracked by the velocity tracker following that one track within it's rate gates.
