Wildfire and Weather Radar: A Review [PDF]

Journal of Geophysical Research: Atmospheres, 2019
AbstractResearch in the pursuit of better understanding of fire behavior and fire‐atmosphere interaction has frequently encountered a dearth of observational data, especially from events that cause most impact. Here we show that meteorological radar has been demonstrated as an effective tool for profiling the microphysics, thermodynamics, and fire ...

Pulse compression for weather radars [PDF]

IEEE Transactions on Geoscience and Remote Sensing, 1998
Wideband waveform techniques, such as pulse compression, allow for accurate weather radar measurements in a short data acquisition time. However, for extended targets such as precipitation systems, range sidelobes mask and corrupt observations of weak phenomena occurring near areas of strong echoes.

Compressed sensing applied to weather radar [PDF]

2014 IEEE Geoscience and Remote Sensing Symposium, 2014
We propose an innovative meteorological radar, which uses reduced number of spatiotemporal samples without compromising the accuracy of target information. Our approach extends recent research on compressed sensing (CS) for radar remote sensing of hard point scatterers to volumetric targets.

Sense and Avoid Airborne Radar Implementations on a Low-Cost Weather Radar Platform

Aerospace, 2017
Traditionally, multi-mission applications in airborne radar are implemented through very expensive phased array architectures. The emerging applications from civilian surveillance, on the other hand, prefer low-cost and low-SWaP (space, weight and power)
