Spaceborne Radar for Space Situational Awareness [PDF]

, 2022
The space environment around planet Earth comprises a variety of nonhomogeneous and nonstationary fluxes of natural and manmade junk. Such debris may collide at hyper-velocity with strategic orbital infrastructure, thus jeopardizing the space economy.

Observing the polar oceans with spaceborne radar [PDF]

, 1986
The application of spaceborne imaging radar data to polar oceanography and sea ice is explored. Several problems come to mind which are presently ripe with ideas and models, but are in need of new data, SAR data, for any progress to be made.

Investigations on the Advanced SAR Processing Algorithms for Security Applications With Distributed Sensing

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
A distributed airborne/spaceborne synthetic aperture radar (SAR) system that consists of a set of monostatic and/or bistatic SARs offers many advantages thanks to the bi-/multiaperture reception.

The Geometry of Spaceborne Synthetic Aperture Radar

, 2018
The paper defines a new coordinate system that was developed in 1977-78 for the world's first digital synthetic aperture radar (SAR) ground processor for images from the Seasat-A satellite. The coordinate system is for the range-Doppler paradigm in the context of a spaceborne platform orbiting a rotating planet.

Spaceborne meteorological radar studies [PDF]

, 1988
Various radar designs and methods are studied for the estimation of rainfall parameters from space. An immediate goal is to support the development of the spaceborne radar that has been proposed for the Tropical Rain Measuring Mission (TRMM).
