Dwell time (radar)
Dwell time 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.
A block of constant PRF and coherently phased RF pulses, is referred to as a coherent dwell interval or coherent dwell time.
