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 ...

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.

Sparsity and Compressed Sensing in Radar Imaging [PDF]
Remote sensing with radar is typically an ill-posed linear inverse problem: a scene is to be inferred from limited measurements of scattered electric fields. Parsimonious models provide a compressed representation of the unknown scene and offer a means for regularizing the inversion task.

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

International Journal of Imaging Systems and Technology, 1992
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 ...

Proceedings of the 16th International Workshop on Mobile Computing Systems and Applications, 2015
Mobile computing is undergoing a significant shift. Where traditional mobile networks revolved around users and their movements, new networks often center around autonomous mobile agents. These include semi-autonomous drones on military missions, vacuum robots search for dirt at home, intelligent cars that deliver us to work, and first responder robots
