-# Every 0.05 seconde:
-# [1] Scans /AI/models for (aircrafts), (carriers), multiplayers. Creates a list of
-#     these targets, whenever they are in radar overall range and are valid.
-# [2] RWR (Radar Warning Receiver) signals are then computed. RWR signal values
-#     are writen under /instrumentation/radar2/targets for interoperabilty purposes.
-# [3] At each loop the targets list is scanned and each target bearing is checked
-#     against the radar beam heading. If the target is within the radar beam, its
-#     display properties are updated. Two different displays are possible:
-#     B-scan like and PPI like.
-#     The target distance is then scored so the radar system can autotrack the
-#     nearest target.
-# Every 0.1 seconde:
-# [4] Computes HUD marker position for the nearest target.
