Exploring Tornado Debris Signature Hypotheses Using Radar Simulations and Large-Eddy Simulations
(2021)
Tornadoes can loft various types and sizes of debris, sometimes resulting in a polarimetric radar signature called the TDS (Tornado Debris Signature). The presence of a TDS in the radar data can help confirm the occurrence ...
Quantifying and Mitigating Debris-Induced Bias in Radar Measurements of Tornadic Winds
(2021)
The centrifuging of lofted tornadic debris is known to cause bias in Doppler radar measurements of tornado wind speeds. Debris presence in a radar volume is associated with anomalous radial divergence, underestimation of ...
Digital predistortion of wideband radar waveforms
(2021-12-17)
As demands for increased radio frequency system performance have grown over time, sufficiently mitigating the distortion introduced by high power amplifiers has proven to be a major challenge to overcome. Digital predistortion ...
