pulse-compression radar

pulse-compression radar

[′pəls kəm‚presh·ən ′rā‚där]
(engineering)
A radar system in which the transmitted signal is linearly frequency-modulated or otherwise spread out in time to reduce the peak power that must be handled by the transmitter; signal amplitude is kept constant; the receiver uses a linear filter to compress the signal and thereby reconstitute a short pulse for the radar display.

In the case of a pulse-compression radar, the transmit waveform's bandwidth B is enhanced by imposing a frequency or phase modulation on the carrier.
