Airborne polarimetric Doppler weather radar: Performance enhancement using AESA technology
2018 IEEE Radar Conference (RadarConf18), 2018Active 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, 2010Detection 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, 1990A 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, 2002A 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.

Sea-surface winds estimation using airborne Doppler weather radar ASTRAIA-ELDORA
1995 International Geoscience and Remote Sensing Symposium, IGARSS '95. Quantitative Remote Sensing for Science and Applications, 2002The aim of the present paper is, using ocean backscatter cross-section measurements, to estimate the surface wind field which is an important parameter involved in latent heat transfer between ocean and atmosphere. The radar cross-section is related to speed and wind direction through an empirical relation for the X-band and the variable polarization ...

Evolution and Prospects of Airborne Weather Radar Functionality and Technology
2005 18th International Conference on Applied Electromagnetics and Communications, 2005This paper presents an overview and analysis of a class of airborne radar systems that usually are named weather radars though traditionally they are multifunctional avionics systems. Functional, methodical, and technological aspects of airborne weather radar are considered. Significant contribution to the content of the paper is taken from the results
