F-14 v2.8 - Jamming, JESTER, and Headless Bodies!
garrya replied to Cobra847's topic in DCS: F-14A & B
Is it in either NAVAIR 01-F-14AAD-1 or NAVAIR 01-F-14A-1 or NAVAIR 01-F-14AAP-1.1 ? I acquire several F-14 manual but couldn't find any information about the ADR -

Thanks alot, how did you learn about ADR?, was a pilot talking about it or did it come from manual? -

So I can understand that you can get target angular direction in JAT mode for ADR estimation. But how do you get target speed and altitude though?. Wouldn’t noise jammer deny range and velocity information? Or basically the Rio just make a guess? I mean how does he even guess the altitude when the only available data is the angle? . It also kinda strange, I can’t find any document talking about ADR, is it same as kinematic ranging on F-15? -

ADR stand for altitude difference ranging right? I have always confused about how it work. Apparently, it allowed range measurement in JAT mode, and thus allow missile to be lofted in HoJ mode. Therefore allow stuff like this: AWG-9 clearly couldn’t burn through a noise jammer at such distance -

Wow that very interesting how far the AWG-9 can burn through jamming. Might i know what is the source? -
I understand that ESM/ELINT measurement are not supposed to be absolute accurate, but I find them somewhat similar to a radar, the angular accuracy of radar is also depend on their beamwidth which is often 2-3 degrees for fighter radars. (Of course radar get range measurement instantly unlike ESM/ELINT system) I get that multiple F-16 can be linked together and measure distance to target very quickly thanks to TDOA. But I’m more curious about single ship geolocation because apparently, according to pilot, a single F-35 can geolocate target quicker and more accurate than 3 F-16

I do understand ESM system work by comparing phase different and resolve the angle from that. So it would need at least 2 antenna in any flat plane to resolved the direction However, recently, I was reading a paper released by LM, they said that their F-35 used an Azimuth only design (basically a linear horizontal array instead of a planar array), so it can only resolve target in azimuth and I find that to be a terrible decision, because by knowing elevation like the APR-47 on F-4G, you can measure the distance instantly in seconds Where as with azimuth only sensor, it is neccessary to fly for 30 seconds at the very least. So I just wonder the HTS is more similar to F-4 or F-35 system
-
This might sound like a very dumb question, but does the ESM system on F-4G (APR47) and F-16CJ (ASQ-213) let the pilot know the threat is below or above them? (aka knowing the emitter elevation) Does the RWR screen get messed up if the pilot spin his aircraft to the side? (his main wing is perpendicular to the ground)
-
So the HTS pod on F-16 (or all RWR) can find target azimuth but no information on elevation, there is no information on whether target is at lower or higher altitude. but what if I roll the aircraft to the side?. Like with half a roll while pointing the nose toward the emitter. Wouldn’t the sensor oriented in the way that allow me to find target elevation, and thus based on my own altitude, I can calculate distance to target?

F-35 eye-watering capability: instantaneous turn rate finishing 135 degrees in 3 seconds Podcast: Behind The F-35’s New Aerial Tricks Aviation Week & Space Technology Apr 03, 2019 Since first flight of the original F-35 test aircraft more than 12 years ago, the U.S. military has given the public only one glimpse of the aircraft’s hotly contested dogfighting chops — and that was nearly two years ago at the Paris Air Show. That’s changing this year. Defense Editor Steve Trimble talks with U.S. Air Force F-35 Demo Pilot Capt. Andrew “Dojo” Olson about the new display’s public debut on March 30 in Melbourne, Florida. http://m.aviationweek.com/defense/podcast-behind-f-35-s-new-aerial-tricks?NL=AW-05&Issue=AW-05_20190404_AW-05_51&sfvc4enews=42&cl=article_2&utm_rid=CPEN1000002990714&utm_campaign=19096&utm_medium=email&elq2=46ce449c64f94ecea82172645d23cd46

Why Red Flag exercises are not indicative of aircraft performance

It say quite clear right there what it is "sustain level turn", besides, the chart represents sustain G
