pulse radar

pulse radar

[′pəls ′rā‚där]
(engineering)
Radar in which the transmitter sends out high-power pulses that are spaced far apart in comparison with the duration of each pulse; the receiver is active for reception of echoes in the interval following each pulse.

A radar in which the transmission consists of short pulses separated by intervals of silence. Such a system employs a single antenna for transmission and reception unlike in continuous wave radar, which has two antennae—one for transmission and the other for reception. A transmission/reception switch connects the transmitter and the receiver to the antenna. Since pulse radar does not transmit continuously, its average power is much less than its peak power. Also called pulsed radar.
