The radar is used to continually scan sectors. It is has a high [[Electric network|power]] demand. It uses 77% of the power generated by one [[Boiler]], so a radar produces indirectly more [[Pollution]], which attracts more biters. The radar itself doesn't attract biters and has to be defended like belts or solar panels. See [http://www.factorioforums.com/forum/viewtopic.php?f=8&t=6008&p=53660#p53660 Let's see your clever builds].

The radar is used to scan continuously the radar area and to steadily explore land.

== Scanning ==

Radar continuously scans a 7x7 [[Chunk]] (224x224 [[Tile]]s), based on the central tile of radar structure chunk is in. This is area is updated within seconds and will for example show all enemy movements. It shows also trains, cars and other players in this scanned area.

== Exploring ==

Radar explores (= scans) one [[Chunk]] every sector scanning progress finishes (open the radar to see this progress).

* It scans the unexplored country first.
* This is done in an 29*29 chunks around the Radar.
* If everything is explored, it repeats the scan process by scanning those chunk, which was scanned the longest time ago.

By doing this, slowly discovers a large area of the map.

=== In other words ===

* As long as you provide the radar with enough energy, it reveals a [[chunk]] every (???) seconds.
* When the radar finishes the sector process, it finds the chunk in the area that wasn't scanned for the '''longest time''' and rescans it.
* In the beginning these are the chunks that are not charted at all and they get discovered.
* Once the radar discovers all the chunks in the area, it will start updating chunks again.

'''It is possible, that the natives will build a new nest or village, while you are not scanning the area. Don't be surprised!

'''So it is always possible, to build more radars, to get more frequent update of the surrounding area.
