What does the letter d mean in the new interface of SAM

yeah its upd all time

Huh, on the official post the “d” column is not shown in the video:

I really want to know what it means 😂

I made a reply on that official thread asking if anyone else knows.

me too

I saw! HAHA, I downloaded it, and uploaded it directly instead 🤣

To be fair, just because I’ve not noticed it doesn’t mean it doesn’t change.

I’m… not very observant which is reflected in my stats

Could be radar cross-section diameter potentially, which would change based on the angle of the aircraft

Found some info, even though this is for weather radar, I think you are probably on the right track: Weather Spotter’s Field Guide - Glossary: D

dBZ

Nondimensional “unit” of radar reflectivity which represents a logarithmic power ratio (in decibels, or dB) with respect to radar reflectivity factor, Z. The value of Z is a function of the amount of radar beam energy that is backscattered by a target and detected as a signal (or echo). Higher values of Z (and dBZ) thus indicate more energy being backscattered by a target.

The amount of backscattered energy generally is related to precipitation intensity, such that higher values of dBZ that are detected from precipitation areas generally indicate higher precipitation rates. However, other factors can affect reflectivity, such as width of the radar beam, precipitation type, drop size, or the presence of ground clutter or AP.

Another link, again, not definitive, but along the same line of thought: Electronic Warfare and Radar Systems Engineering Handbook - Abbreviations & Acronyms - RF Cafe

  • d Distance, Diameter, or deci (10-1 multiplier)

SO, if any of this info is close to the correct idea, I would think that a higher “d” value (especially over 1.0) would indicate a higher likelihood of a good lock, and better chance of interception etc.

So I’m guessing that means distance to predicted intercept point/missile flight distance?

THAT might make sense, but it’s definitely not distance from SPAA directly to target, because there is already a range column.

But, it does seem to be some sort of formula/calculation, because it seems like 1.0 is “0”. IE, it keeps floating around 1, but going under 1.0 and above. AND when you resort the “d” column, it shows “d-” or “d+” which to me implies some sort of formula rather than a pure measurement/reading.

Well the missile doesn’t reach the target instantly, it’s gotta lead it. So like with the prop with basically no radial velocity the two distances are the same. But for the jet it’s closing at 81m/s so the missile doesn’t need to fly as far because the target will be closer to the launch vehicle at the time of impact. At least that’d be my updated guess

  • and - its only about filter on or off, on other columns u can see the same

I am not sure what you mean, could you expand/go into further detail?

this only displays when a filter is applied to a particular column, for example, IFF+ equals that allied targets will go first, and then only enemy ones, and vice versa, in that column, according to the same principle, only according to a different pattern, not like in the IFF column
