pulse repetition frequency

1. In lasers, the number of pulses that occur each second.
2. In radar, the number of pulses that occur each second. Pulse repetition frequency should not be confused with transmission frequency, which is determined by the rate at which cycles are repeated within the transmitted pulse. Also called PRF. See also laser.
