Jittering is due to the radar noise, which i've tried to lower using a filter but it still jitters a lot, and vehicle speed is taken into account. I'll upload a better version which doesn't jitter eventually.

is there a way to take into account vehicle speed and reduce the jittering?

It has to do with the delay that the microcontroller introduces. I have made a new version, which does take this into account, but there are a few things that I still have to improve. It will eventually be on the workshop.

the gun is pointing nowhere near where it should what am i doing wrong

If you want to use depricated radars with this microcontroller right now, do the following:
Place two depricated radars next to each other, one vertically and one horizontally.
Then connect the distance node to the first channel in a composite signal.
Then connect the elevation angle from the vertical radar to the second channel.
Connect the elevation angle from the horizontal radar to the third channel.

After you've done that connect the composite output to the composite input of the microntroller.
In the microcontroller remove all the lua scripts and connect the nodes back together where the lua scripts used to be, or remove all codes in the scripts and paste in

"function onTick()
output.setNumber(1, input.getNumber(1))
end"

(there are 4 Lua scripts total).

It should not shake anymore when you've done that. If it doesn't aim in the direction of your target, try inverting the elevation values.

It's shaky because I'm using one of the new radars and haven't found a good way to reduce the noise created from them, which is why I'm using a filter. It reduces the noise a little but it's still kinda bad. I was testing this microcontroller using the depricated radar, which doesn't shake. I'll upload that version in a week or two when I've finished polishing it.

Why is it so extremely shakey, like it is jiggling so much it is insane
