Weather Detection with an AESA-Based Airborne Sense and Avoid Radar

2020 IEEE Radar Conference (RadarConf20), 2020
Modern radar systems shall provide multifunctional capabilities because airborne applications typically demand sensor equipment, which has optimized size, weight and power. Therefore the use of multifunctional sensors is necessary and efficient. This work represents the first weather radar data of flight tests of such an multifunctional AESA (Active ...

Airborne polarimetric Doppler weather radar: Performance enhancement using AESA technology

2018 IEEE Radar Conference (RadarConf18), 2018
Active electronic scanning array (AESA) enables rapid scanning, and the radar beam could be steered to any angular direction nearly instantly. Rapid steering of the antenna beam is suitable for beam multiplexing. Beam multiplexing (BMX) enables the collection of independent sample pairs of radar signals that reduce errors in radar measurements while ...

Detection of Turbulence with Airborne Weather Radars using Space-Time Filtering

IEEE Transactions on Aerospace and Electronic Systems, 2010
Detection of hazardous atmospheric zones with a high level of turbulence is a crucial problem for airborne weather radars. Usually it is solved via estimation of the spectrum width of weather echoes. Unfortunately atmospheric turbulence is not the only phenomenon that increases the spectrum width in airborne weather radars.

Range profiling of the rain rate by an airborne weather radar

Remote Sensing of Environment, 1990
A class of methods based on a measure of path attenuation that is used to constrain the Hitschfeld-Bordan solution is investigated. Such methods are investigated for lidar, radar, and combined radar-radiometer applications. Their function is to allocate the attenuation in proportion to the strength of the measured reflectivity.

Determination of windspeed within a weather storm using airborne Doppler radar

IEEE Proceedings of the SOUTHEASTCON '91, 2002
A real-time airborne pulse Doppler radar signal simulator is developed to detect low-altitude windshear. Using the numerical simulation model of an isolated microburst the radar returns from the undesired objects are obtained using appropriate probabilistic models.
