Science, 1991
Full disk images of Mars have been obtained with the use of the Very Large Array (VLA) to map the radar reflected flux density. The transmitter system was the 70-m antenna of the Deep Space Network at Goldstone, California. The surface of Mars was illuminated with continuous wave radiation at a wavelength of 3,5 cm.

Shuttle Imaging Radar Experiment
Science, 1982The 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.

Journal of Geophysical Research, 1976
The paper presents a set of seven radar brightness images and the corresponding altitude contours of small portions (circular regions of 1500-km diameter) of the Venus surface located at the center of the disk taken in the winter of 1973-1974. The regions imaged are arranged in an equatorial belt on the one face of Venus which is always seen on the ...

AbstractRadar systems combining coherent signals with frequency and angular diversity offer the possibility of synthesizing images of complex objects with spatial resolution of a few wavelengths. The availability of high‐quality microwave sources and components, high‐speed digital computers, and efficient signal‐processing algorithms allows radar ...

Why is there so much interest in space radar systems? Radar is the way to monitor changing events in a reliable manner as it is largely independent of weather – particularly useful for Europe which is so often widely cloud-covered.

We introduce a new approach to radar imaging based on the concept of compressive sensing (CS). In CS, a low-dimensional, nonadaptive, linear projection is used to acquire an efficient representation of a compressible signal directly using just a few measurements.
