Correlation between cosmic noise absorption and VHF coherent echo intensity [PDF]
, 2005 International audienceWe present examples and statistical analysis of the events with statistically significant correlation between the cosmic noise absorption (CNA) and the signal-to-noise ratio (SNR) of the VHF coherent echo intensity in the area ...

The radar signature of the Wind Lens: a less disruptive wind turbine? [PDF]
, 2012 We study the radar signature of a new type of wind turbine, named the Wind Lens. This design includes a flanged shroud around the turbine which concentrates the wind flow past the turbine blades and hence improves the efficiency.

Bistatic noise radar: Demonstration of correlation noise suppression
IET Radar, Sonar & Navigation, 2023 In this study, spatial separation of the radar transmitter and receiver units is considered, as a means of reducing the masking effect in noise radars.

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 ...

Coherent Integration Loss Due to Nonstationary Phase Noise in High-Resolution Millimeter-Wave Radars
Remote Sensing, 2021 Phase noise refers to the instability of an oscillator, which is the cause of instantaneous phase and frequency deviations in the carrier wave. This unavoidable instability adversely affects the performance of range–velocity radar systems, including ...

Techniques for homodyne dechirp-on-receive linearly frequency modulated radar [PDF]
, 2011 This thesis presents work done to extend and improve the operation of homodyne dechirp-on-receive linearly frequency modulated radars. First, an investigation of the effect of common phase errors on the point response function of the radar is ...
