Phased-MIMO Radar: A Tradeoff Between Phased-Array and MIMO Radars [PDF]
, 2009 We propose a new technique for multiple-input multiple-output (MIMO) radar with colocated antennas which we call phased-MIMO radar. The new technique enjoys the advantages of MIMO radar without sacrificing the main advantage of phased-array radar which ...

Wave Measurements Using Multi-Frame Processing of Marine Radar Data
Sensors, 2021 Marine radars have proven to be useful for measuring ocean waves, but the accuracy of the measurements is limited by several factors including the look-angle dependence of the radar signals as well as noise in the radar data.

An improved hydrometeor detection method for millimeter-wavelength cloud radar [PDF]
Atmospheric Chemistry and Physics, 2017 A modified method with a new noise reduction scheme that can reduce the noise distribution to a narrow range is proposed to distinguish clouds and other hydrometeors from noise and recognize more features with weak signal in cloud radar observations ...
