MIMO phased-array for SMTI radar
2009 International Waveform Diversity and Design Conference, 2008Waveform diversity techniques for radar have gained considerable interest over the past several years. Novel radar waveforms have been proposed to improve detection performance and metric accuracy (i.e., angle estimation performance). This paper explores the potential for using a waveform diversity technique known as multiple input, multiple output ...

Benefits of Digital Phased Array Radars
Proceedings of the IEEE, 2016In this paper, an overview is given of the radar benefits of digital arrays in comparison with conventional phased arrays. Considered are passive and active phased arrays as well as subarray- and element-level digital arrays; their key differences are highlighted.

IEEE Spectrum, 1968
An array antenna can enlarge the capability of a radar system by contributing beam-pointing agility as well as providing a way of handling large power. The fundamental theory of such antennas was outlined in IEEE Spectrum exactly four years ago.1 Advances in the art have been so impressive that this month's Proceedings of the IEEE is a special issue on

Electronics & Communication Engineering Journal, 1990
Array antennas were used in early radar systems. Today's microwave phased arrays with electronic beam-steering allow surveillance and tracking with variable data rates in a multifunction radar. The paper reviews system options and discusses the engineering of active arrays, using as an example the Siemens Plessey Radar/ARE MESAR, which is now ...

Solid state phased array radar
1974 Antennas and Propagation Society International Symposium, 1974The system advantages and limitations imposed by the solid state phased array radar are reviewed. The implications of these factors on the radar subsystems are discussed and the characteristics of the U.S. Army test bed solid state radar are presented.

The Jicamarca phased-array radar
2013 IEEE International Symposium on Phased Array Systems and Technology, 2013Phased array and spaced antenna radar techniques developed and employed at the Jicamarca Radio Observatory for ionospheric research are reviewed. The ionospheric scatterers studied by Jicamarca are not spatially homogeneous and not beam filling in some cases, and distinguishing the bearing of the radar backscatter is essential for correctly ...
