The use of pseudo-noise phase modulation in meteorological Doppler radars
Abstract
It is shown that pseudo-noise (PN) phase modulation of Doppler radar parameters can be used to adapt the radar pulses to a meteorological target. The specific radar parameters used in PN phase modulation are: range resolution; maximum unambiguous range; and unambiguous Doppler velocity. An 8.6-mm-wavelength Doppler radar incorporating a PN phase modulation scheme is described. The radar has been used to measure the time variations of drop-size distributions in rainfall and for monitoring physical processes in clouds and precipitation. The data processing and acquisition system of the meteorological Doppler radar are described in a block diagram.
