RADAR SYSTEMS IN TODAYS NAVY
There are too many radar systems used in todays
Navy to cover in this volume.
However, table 1-2
provides an overview of the radars and sensors in use,
by AN system designator, ship class, and related FC
systems.
SUMMARY
Radio, detecting, and ranging (radar) uses radio
frequency (RF) energy and a complex integration of
computers, displays, and support equipment to detect a
target. However, radar is just one type of sensor that is
available to the modern Fire Controlman. Other types
of sensors (e.g., infrared and optical) use different
