Dwell time (TD) in surveillance radar is the time that an antenna beam spends on a target. The dwell time of a 2D–search radar depends predominantly on

  • the antenna's horizontal beam width θAZ, and
  • the turn speed n of the antenna (in rotations per minute or rpm, i.e. 360 degrees in 60 seconds = multiplied by a factor of 6).

    • Dwell time is calculated by:

    T D = θ A Z 6 ⋅ n (in seconds)
