The shuttle imaging radar (SIR-A) acquired images of a variety of the earth's geologic areas covering about 10 million square kilometers. Structural and geomorphic features such as faults, folds, outcrops, and dunes are clearly visible in both tropical and arid regions. The combination of SIR-A and Seasat images provides additional information about the surface physical properties: topography and roughness. Ocean features were also observed, including large internal waves in the Andaman Sea. 

Overview of the Shuttle Imaging Radar-B Preliminary Scientific Results

The Shuttle Imaging Radar-B experiment consisted of a large number of scientific investigations in the earth sciences to study the generation and propagation of surface waves, the dynamics of internal waves, oil slick detection, and the properties of southern polar ice.

Spaceborne Radar Subsurface Imaging in Hyperarid Regions

Imaging data acquired with the Shuttle Imaging Radar (SIR-A) over the hyperarid region of Egypt/Sudan clearly show surface penetration through the sand cover. Even though absorption does occur in the

Radar Images and Geoarchaeology of the Eastern Sahara

The first Shuttle Imaging Radar (SIR-A) instrument was flown in earth orbit in November 1981. Data were obtained pertaining to a flat, sand-covered region in the eastern Sahara of North Africa. These

The Shuttle Radar Topography Mission

The Shuttle Radar Topography Mission produced the most complete, highest-resolution digital elevation model of the Earth, using dual radar antennas to acquire interferometric radar data, processed to digital topographic data at 1 arc sec resolution.

An overview of spaceborne imaging radars presently flying or under development is presented, to allow quantitative measurements of surface and near‐surface geophysical parameters and monitoring of surface processes over long‐term duration.

Shuttle imaging radar views the Earth from Challenger: The SIR-B experiment

In October 1984, SIR-B obtained digital image data of about 6.5 million km2 of the Earth's surface. The coverage is mostly of selected experimental test sites located between latitudes 60 deg north

Space Imaging Radar in Planetary Exploration and Earth Observation

Spaceborne imaging radars are becoming key tools for mapping Earth and planetary surfaces and near subsurface. Developments in the past decade are leading to capabilities for three-dimensional

Spaceborne synthetic-aperture imaging radars: Applications, techniques, and technology

In the last four years, the first two Earth-orbiting, space-borne, synthetic-aperture imaging radars (SAR) were successfully developed and operated. This was a major achievement in the development of

Remote sensing of the Earth with spaceborne imaging radars

Spaceborne imaging sensors in the visible, infrared and passive microwave have been used to observe and study the Earth's surface since the early stages of the space program. More recently, active

Synoptic, large-area radar images of the earth's land and ocean surface, obtained from the Seasat orbiting spacecraft, show the potential for geologic mapping and for monitoring of ocean surface

Spaceborne and airborne imaging radar observations of sand dunes

Seasat and aircraft radar imagery of five areas of sand dunes in the southwestern United States and northwestern Mexico have been studied and compared to Landsat imagery and air photos. Radar imaging

Radar sensors are being used to provide two-dimensional imagery of the ocean surface. The radar image has a brightness variation which is proportional to the local backscatter cross-section of the

Internal Solitons in the Andaman Sea

Using theoretical results from the physics of nonlinear waves, it is shown that the internal waves are solitons and their interactions with surface waves are described.
