TL;DR: In this paper, a synthetic aperture radar (SAR) target simulator for simulating the radar return, or echo, from a target seen by a SAR antenna mounted on a platform moving with respect to the target includes a first-in-first-out memory (26) which has digital information clocked in at a rate related to the frequency of a transmitted radar signal and digital information timed out with a fixed delay defining range between the SAR and the simulated target, and at a time related to frequency of the return signal.

TL;DR: The surface of Titan, Saturn's largest moon, appears to consist of solid hydrocarbons or CO2 with considerable small-scale structure, according to a new electromagnetic scattering model that uses both Cassini radar reflectivity and emissivity measurements.

TL;DR: In this paper, the relationship between radar backscatter and aerodynamic roughness of bare rocks and soils was investigated using calibrated multiple wavelength, polarization, and incidence angle aircraft radar data, and applied the results to models to gain an understanding of the physical properties which produce the relationship.

TL;DR: It is confirmed that the phase artifacts in the Iceland interferogram are due to dispersive ionospheric propagation rather than other decorrelation factors such as neutral atmospheric delays, and confirmation of the cause of the image artifacts suggests that they can be routinely corrected from the InSAR data alone, provided that the sensor measures the change in TEC along the radar swath.
