A Micro-Doppler Modulation of Spin Projectile on CW Radar
ITM Web of Conferences, 2017 To obtain the spin speed of projectile effectively, a micro-Doppler modulation model of rotating projectile measured by continuous-wave radar (CW radar) is introduced.

Servomechanism for Doppler shift compensation in optical correlator for synthetic aperture radar [PDF]
, 1980 A method and apparatus for correcting Doppler shifts in synthetic aperture radar data is described. An optical correlator for synthetic aperture radar data has a means for directing a laser beam at a signal film having radar return pulse intensity ...

A radar‐based investigation of precipitation growth and decay in South Korea
Quarterly Journal of the Royal Meteorological Society, EarlyView.Within a Lagrangian framework, we quantitatively retrieved and assessed precipitation growth and decay using the South Korean radar network, focusing on spatial patterns over the unique geographical features, including complex topography and land–ocean boundaries. Our findings indicate that the precipitation growth and decay is significantly influenced

S-Band Doppler Wave Radar System [PDF]
Remote Sensing, 2017 In this paper, a novel shore-based S-band microwave Doppler coherent wave radar (Microwave Ocean Remote SEnsor (MORSE)) is designed to improve wave measurements. Marine radars, which operate in the X band, have been widely used for ocean monitoring because of their low cost, small size and flexibility.

Quarterly Journal of the Royal Meteorological Society, EarlyView.We explore the variance of the radar–rain‐gauge combination kriging‐based system “CombiPrecip”, showing that it represents satisfactorily the radar–rain‐gauge precipitation uncertainty around the kriging expected value. We then present a method to generate ensembles out of it, which we find to be very similar in texture with the expected‐value image ...

Methods for verifying the accuracy of wind profiles [PDF]
, 1986 Comparisons of radar-measured winds have been made with several types of measurements not only to verify radar data but also to seek a satisfactory comparison method.

Quarterly Journal of the Royal Meteorological Society, EarlyView.The variation of rainfall and its diurnal cycle with the Madden–Julian oscillation over coastal regions of NE Australia exhibit both large‐scale and local‐scale influences. The widespread increased rainfall is driven by large‐scale forcings, while the local enhanced rainfall is likely affected by mesoscale coastal processes. The variation of convective

Progress in existing and planned MST radars [PDF]
, 1986 Radar systems are described which use two different wind measuring techniques: the partial-reflection drift technique and the mesosphere-stratosphere-troposphere (MST) or Doppler beam-swing radar technique.

Quarterly Journal of the Royal Meteorological Society, EarlyView.During July 2021 there were widespread reports of flooding across the equatorial Maritime Continent. This analysis reveals how interactions between a system of convectively coupled Kelvin waves (CCKWs) and diurnally phase‐locked westward‐propagating inertio‐gravity waves during an active Madden–Julian Oscillation (MJO) caused these extreme rainfall ...
