MIMO Radar with Widely Separated Antennas
IEEE Signal Processing Magazine, 2008 A review on Multiple-input multiple-output (MIMO) radar is given that is with widely separated antennas. MIMO radar is an architecture that employs multiple, spatially distributed transmitters and receivers and is even considered as a multistatic radar ...

MIMO Radar with Colocated Antennas
IEEE Signal Processing Magazine, 2007We have provided a review of some recent results on the emerging technology of MIMO radar with colocated antennas. We have shown that the waveform diversity offered by such a MIMO radar system enables significant superiority over its phased-array counterpart, including much improved parameter identifiability, direct applicability of adaptive techniques

UWB Antenna for a Radar Sensor
2020 13th International Conference on Communications (COMM), 2020In the last years ultra wide band (UWB) signals have more and more applications, including radar sensors. These systems need an antenna as an interface with the propagation media. The paper refers to an UWB antenna employed for a radar sensor used for subsurface searching, describes the method used to measure the parameters of the antenna and presents ...

Radar imaging based on rotating antenna
ICASSP-88., International Conference on Acoustics, Speech, and Signal Processing, 2003A radar imaging method for terrain is introduced in which the radar is suspended in the air, but the radar antenna is rotating. The relation between echo signals and the terrain image (the absolute value of terrain reflectivity) is examined. An imaging method called equal-range projection deconvolution is the derived, and an algorithm reconstructing ...

Photonic feedback control for radar antennas
2012 Tyrrhenian Workshop on Advances in Radar and Remote Sensing (TyWRRS), 2012A feedback control network based on photonic sensors has been exploited to increase resiliency of large phased arrays for radar and space applications has been proposed. The sensor network is embedded in the antenna array front-end such to provide a a real-time control of the failures/calibration errors of system components.

The influence of radome on radar antennas system
2012 9th International Conference on Communications (COMM), 2012This paper aim is to study the influence of a radome on the air surveillance radar systems. The study was performed using numerical methods, due to the problem complexity. It is very hard to accomplish a complete realistic study because of huge electrical dimensions but we can get some conclusions to improve the radar-radome assembly.
