make a alert signal that beeps whenever a entity that is armed is near to you in a local radius

Its difficult to define if a entity is armed or not. I could add a config option to add armed vehicles that will trigger an alert

the possibly shut the Radar down VIA EMP devices
there many addons that has such EMP devices

for the config, can you add it to the context menu for easy use.

@Patrick Can you link the most popular EMP Addons i should make it to work with?

the mod is nice but it would be better if the radar detects planes in the map boundaries because it looses track of the plane after the plane lifts off

like the radar extends to the map's edge boundaries

because it looses track of it very quick

also you should make the icon move

also you can put a dot in the centre for to show where you are

The radius of the radar can be extended as far as you like, see the console command in the description.
Also making the dots on the radar move would make it less realistic but primarily much more extensive when it comes to performance, since the positions and tracking would need to be calculated every frame per second.

@Mekphen not a feature, but is it possible you can give your radar an icon, i got an image of one, all you need to do is, make a folder called entities in the materials folder, i have an image of the icon here: https://i.imgur.com/MoPVBGX.png (rename the image to ent_scifi_radar and put it in the entities folder) and you're done! (the image has to be i beleive 512x512 and 256x256), now it's because most entities on the workshop have icons, again, this is your addon, but if it helps, then good, take care!
