A/G radar shows only moving targets?

A Doppler Radar is going to have the strongest signal from something moving.

 

You can see static objects if you are close enough and the ground is flat, you can also see runways but it is difficult. It will be much easier once DBS/EXP modes are implemented but they still won’t light up as a brick the way moving objects do

The A-G radar ain't magical all revealing. Not even all moving targets become visible with it, and some static ones can be visible.

 

But once ED implements the real military tactics, you will notice that even moving ground vehicles becomes invisible to the radars as modern militaries (since 80's) use camouflage nets that are anti-radar and even anti-thermal.

The vehicle crews will do all their power to hide their vehicles from the air, vehicles are driven near the forests, parked inside the forests edges and under trees and treelines, vehicles gets camouflaged with the trees, grass, nets etc making their hard edge/flag surface shapes invisible to radars, thermal becomes trouble only at specific situations and directions etc. And crews as well use a simple reflector devices (small diamond shaped metal ones) that they hang around different places that will cause A-G radars to get strong reflection and detects it as a vehicles, regardless there ain't any. And smart infantry place those to all kind fancy places and ways that generate long movements and that gets A-G radars go crazy that there is ground vehicles moving.

Default MAP mode is to draw a basic map, EXP/DBS is not correctly implemented at the moment, the one in the game is just a placeholder.

 

Buildings, tanks, shelters will all reflect the radar signal, its hard for the radar to tell what is what if the signal is static.

 

So if U want to AG radar to show some "contact" then its either a moving target, or a very clear target on the sea. Ground tgt may be showed as a contact in some case, but its a good idea to use TGP to ID the static targets.

Static targets in general won't show a synthetic return, which is what those bricks in GMT are (as well as SEA).

 

They would, however, show on a map. The higher the resolution of the map, the smaller objects you will be able to see. Right now DBS/EXP are satelite maps, but the idea is similar in the way that the satelite view uses the visible part of the EM spectrum and the radar operates in the radio part. There is no physical reason objects like hangars, warehouses, ammo dumps and bunkers wouldn't show on a radar map, as the radar map is only using the doppler effect to sharpen the resolution as opposed to an actual filter. They just won't show as a synthetic brick because the radar isn't in a mode where it can make assumptions. I.e., in GMT the radar can assume you are looking for a moving target on the ground. In mapping modes you're saying "show me what this area of the Earth looks like at X resolution"

Map draws based on strength of signal return. Buildings return strong signals, water will be pretty weak/weakest, so they range from bright green to black. The rest of the picture is interpretation by the human mind.

 

GMT uses a filter. Static objects regardless of type will return a signal at a certain frequency range but parts of the signal will have doppler shift due to relative motion, so the RADAR will only show those areas. Most of the picture will be black with some noise.

 

GM is like MAP but with a filter so the signal is reduced below the noise floor with only the stronger returns being painted. This is why some objects appear and others don't.
