Microphysical cross validation of spaceborne radar and ground polarimetric radar
IEEE Transactions on Geoscience and Remote Sensing, 2003Ground-based polarimetric radar observations along the beam path of the Tropical Rainfall Measuring Mission (TRMM) Precipitation Radar (PR), matched in resolution volume and aligned to PR measurements, are used to estimate the parameters of a gamma raindrop size distribution (RSD) model along the radar beam in the presence of rain.

Spaceborne synthetic aperture radar instrument modelling
IEE Colloquium on Radar System Modelling, 1998Future spaceborne and airborne synthetic aperture radar (SAR) systems will have greatly enhanced flexibility due to the advances in technology currently being made. An important aspect of any SAR programme is the ability to predict the performance of the instrument, particularly during the design and development stages.

Spaceborne rain radar mission and instrument analysis
IGARSS '96. 1996 International Geoscience and Remote Sensing Symposium, 2002The main objective of this paper, based upon a Pre-phase A study founded by ESA, is to define a preliminary design of a spaceborne rain radar from a precise review of user requirements proposed for climate research and operational meteorology purpose. A mission analysis defines the most suitable space segment, taking into account the instrument related

Parallel processing of spaceborne imaging radar data
Proceedings of the 1995 ACM/IEEE conference on Supercomputing (CDROM) - Supercomputing '95, 1995We discuss the results of a collaborative project on parallel processing of Synthetic Aperture Radar (SAR) data, carried out between the NASA/Jet Propulsion Laboratory (JPL), the California Institute of Technology (Caltech) and Intel Scalable Systems Division (SSD).

Improvement to radar reflectivity factor algorithm for spaceborne precipitation radar
IET Conference Publications, 2009Study of spaceborne precipitation radar retrieval algorithms is important in both algorithm development and data application. This paper presents improvement to radar reflectivity factor retrieval algorithm, which introduces equivalent raindrop diameter in each resolution cell and judges whether the scattering obeys Rayleigh condition.

Spaceborne Bistatic Synthetic Aperture Radar
2008In order to maintain adequate swath overlap along the orbit, BSAR missions require careful selection of orbits and pointing which must also take into account system-level issues, for instance: impacts on transmitting/receiving radar mission, requirements on bistatic payload/bus, lifetime.

Adaptively Pointing Spaceborne Radar for Precipitation Measurements
Journal of Applied Meteorology, 1982An auxiliary concept of adaptive pointing is presented as an aid to space-based measurements of precipitation using microwave radar. It is recommended that the instantaneous field of view (IFOV) be limited to cloudy regions of possible precipitation rather than scanning clear-sky areas of no interest.

Submesoscale eddies seen by spaceborne radar
2013In the present study, synthetic aperture radar (SAR) imagery was used to derive statistics on spiral eddies in the eastern Mediterranean and Black seas. The dataset used consists of about 1700 medium resolution Envisat ASAR and ERS-2 SAR images obtained in 2009-2011.
