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 ...

Abstract : Research effort was directed toward the investigation of components, techniques, and fundamental theoretical limitations of arrays for long-range radar applications. Research on components for arrays includes low-noise RF amplifiers, highpower modular transmitters, high-speed building blocks for data- processing systems, high-speed microwave

Large phased‐array radars can play a very important part in arms control. They can be used to determine the number of RVs being deployed, the type of targeting of the RVs (the same or different targets), the shape of the deployed objects, and possibly the weight and yields of the deployed RVs.

Phased array weather / multipurpose radar
IEEE Aerospace and Electronic Systems Magazine, 2010The first phased array radar dedicated to weather observation and analysis is now instrumented with eight simultaneous digital receivers. The addition of these additional channels will enable the use of advanced signal processing to improve signal/clutter in an adaptive mode.

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.

Optically controlled phased array radar
International Topical Meeting on Microwave Photonics. MWP '96 Technical Digest. Satellite Workshop (Cat. No.96TH8153), 2002The experimental results presented in this paper indicate that optically driven phased array antennas with high performance and true time delay can be practically implemented. The paper concentrates on the potential performance of optically driven antenna systems using a coherent WDM architecture.

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 ...

Some MIMO radar advantages over phased array radar
2010 The 2nd International Conference on Industrial Mechatronics and Automation, 2010MIMO radar is a new radar technique developed recently. It can achieve better detection performance than conventional phased radar. In this paper, we investigate some advantages of MIMO radar on the non-ideal factor of transmitting signal such as the instability in signal phase and the spur in transmitting signal etc.

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
