Inverse Problems, 2013
Because of their ability to operate without regard to day, night or weather conditions, radar systems are ubiquitous in remote sensing operations and are used in a wide variety of commercial and military applications. High resolution radar imaging, however, is a remote sensing subcategory that requires raw radar data to be collected over an ...

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.

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 ...

AbstractThe Seasat and Shuttle imaging radars flown in the 1970s and 1980s established a strong scientific and technical base for a number of imaging radars that are flying or under development. Recent advances in understanding wave‐surface interactions, utilization of multispectral and polarimetric data, as well as advances in microwave and electronic

16th European Microwave Conference, 1986, 1986
This paper is concerned with the problem of obtaining an image by means of a spatially coherent radar signal processing. After a brief review of the above technique, the problems of motion compensation (target tracking) and of 2D-Fourier inversion, arising in practical realisations, are discussed. In addition, the possibility of extending the theory to
