Mostly the lack of signal to noise ratio comparison when deciding if a seeker should be decoyed by chaff. In game RCS depends on direction but it’s not as drastic as real life. In game it’s a modest 1.1X increase if memory serves correct. But IRL it’s often ~10 ~20dB, which is a ~10X ~100X increase in relative RCS. As such larger aircraft’s such as Su-27, F-14, Tornados should have less protection from a single drop of chaff if the same chaff was deployed on a JAS39 for example.
However this would most likely make the seekers to strong.
Yet it has unintended consequences. Look at radars that use a LPRF waveform. A single chaff is able to transfer lock to it, rendering them useless with a single one.
10m² frontal may just be an example but they do increase to higher order of magnitude, 20-30dBsm, from the side aspect
You first just quote a made up drawing, I don’t know why lol
Then you quote a computer simulation (which according to you is not useful due to reasons, example su57s plots)of a SU-27, without any frequency or scattering region mention, nor even element count. Yet you see it climb to 30dBsm on the sides.
Secondly, its not 20 or 30 times. But dBsm. 30x isn’t 30dB
Here you have a 21 in the optical region. 27-29 dBsm at 90° aspectdBsm
T-33. 20-25 dBsm at sideaspect.
computer sim of F-22 also spikes to 20dBsm side aspect.
B57, 22dBsm at side aspect.
BQM-34 drone RCS, also spikes to 20dBsm side aspect.
They all tend to rise to an order of 20-30 dBsm at sides. Dunno why you fight it, it’s just a fact. Other aircraft dedicated specifically made to reduce RCS is another subject
Do you even know what decibels are? how they are calculated from linear units? HOW TO PASS THEM FROM dB TO LINEAR?
It says 10 dBsm front and 30dBsm sideaspect. I’ll let you figure that out yourself
He knows. The lines on the left which correspond to a real aircraft and the right with reduced RCS. The line of the left are impossible to read tbh. And you have another set of graduation 1 and 2 which are an average ±30° or something like that, which I don’t understand.
Either way, it’s a computer simulation, which he generally discards like on others like the SU57. But either way. 10dBsm front and 30dBsm at the sides is reasonable.
Where does it say m^2? That is scale logarithmic using decibels, you should have better intuition reading these kind of charts, dBsm or log is the standard as RCS varies alot.
Its not an exaggeration. RCS is comically large from the sides as you saw above. 20-30 dBsm from the sides isn’t a joke. AT certain frequencies I’ve seen spikes up to 40dBsm at certain frequencies and just low RCS from things you’d expect huge. You really can’t say much of RCS without mentioning wavelength or polarization used, but you can talk with order of magnitude with decibels.
