AvroLanc Posted January 30, 2019 Share Posted January 30, 2019 Just found a good graphic of some of the AWG-9 Pulse Doppler modes and scan limits in a book of mine. What's interesting I think is the launch zone symbol in the bottom left. Hopefully this will be implemented as is, on the TID. Getting more pumped up for this day by day.

It's not shown in you're image, but there's also a ±10°/8 bar, TWS scan pattern. Link to comment Share on other sites More sharing options...
Dino Might Posted January 30, 2019 Share Posted January 30, 2019 DDD display, is the vertical scale closure rate? What is the arc on that display signifying? Link to comment Share on other sites More sharing options...
FWind Posted January 30, 2019 Share Posted January 30, 2019 Nice post AvroLanc. It's not shown in you're image, but there's also a ±10°/8 bar, TWS scan pattern. ±10°/1 bar supersearch pattern Link to comment Share on other sites More sharing options...
Naquaii Posted January 30, 2019 Share Posted January 30, 2019 As far as we know the TWS is either 2 bars +/- 40 degrees or 4 bars +/- 20 degrees. The DDD in the pulse doppler mode is rate along the y axis, so speed relative own aircraft. The arc shown is the ground returns at zero groundspeed (ground clutter), called the MLC or main lobe clutter. And yes, the supersearch is +/-10 degrees in one bar and is used for manual target acquisition for transfer to STT. Link to comment Share on other sites More sharing options...

The workbook I have states that the ±10°/8 bar scan pattern, is available in TWS-M only. Link to comment Share on other sites More sharing options...
Naquaii Posted January 30, 2019 Share Posted January 30, 2019 The workbook I have states that the ±10°/8 bar scan pattern, is available in TWS-M only. That's probably a later developement then, it's not in our documentation. Link to comment Share on other sites More sharing options...
Blaze1 Posted January 30, 2019 Share Posted January 30, 2019 That's probably a later developement then, it's not in our documentation. The vast majority of my workbook is dated 1980, with earliest date being 21st January 1980 and the latest being 28th July 1980. The TWS section in question, is dated 10th March 1980, if that helps for comparison. Link to comment Share on other sites More sharing options...
AvroLanc Posted January 30, 2019 Author Share Posted January 30, 2019 (edited) Any word of the launch zone symbol Naquaii? Can we expect to see this on the TID? Edit: Ahh, just seen the following image. Looks like the symbols are there on the Velocity Vectors of the TWS targets (centre TID image)?

Naquaii Posted January 30, 2019 Share Posted January 30, 2019 Excellent, although I’m a little unsure on how to interpret them. I’m sure all will become clear. When the launch zone symbology is activated the track vector (line from the symbol center dot) changes from representing the track speed to representing a timeline of 180 seconds. That line then represents the time until minimum launch range which is the dot in the center that the line eminates from. Along the line you then also have the maximum range dot and the optimum range box. As the vector shortens (as the time until rmin shortens) the end of the vector line then reaches the rmax dot and then the optimum range box and that represents when you're at those points. A bit of a mindtwist but not too bad when you're used to it! :-) Link to comment Share on other sites More sharing options...

PLZ By Salamander Books, Author Mike Spick Nothing really that revolutionary, but a nice collection of books from the 80's. Don't make 'em like this anymore.
