Digital beamforming in sar systems

IEEE Transactions on Geoscience and Remote Sensing, 2003
The rapid progression in digital hardware and signal processing capabilities stimulates the development of radar systems. The tendency is to move the digital interface toward the antenna, replacing, whenever possible, analog RF-hardware. Based on software codes, these digital systems are more flexible and easier to reconfigure than RF-hardware.

Keynote presentation: SAR systems

2011 IEEE International Conference on Microwaves, Communications, Antennas and Electronic Systems (COMCAS 2011), 2011
Synthetic Aperture Radar (SAR) systems are becoming increasingly important sensors in as well the military environment as in the civilian market. In this keynote presentation an overview will be given over more than 2 decades of SAR system∼ and SAR application development at TNO in the Netherlands.

The ONERA RAMSES SAR system

IEEE International Geoscience and Remote Sensing Symposium, 2003
The ONERA RAMSES system (Radar Aeroporte Multi-spectral d'Etude des Signatures) is a flexible SAR system in constant evolution developed mainly as a test bench for new technologies and to provide specific data for TDRI (Target Detection, Recognition and Identification) algorithm evaluation.

Spaceborne SAR systems and technologies

2010 IEEE MTT-S International Microwave Symposium, 2010
Design and development of Spaceborne Synthetic Aperture Radar Systems is one of the major activities at EADS Astrium, Friedrichshafen, Germany. Examples of recent and current developments are the TerraSAR-X and the TanDEM-X Satellites, both operating at X-band with multi-polarization capability.

SARS: A Health System's Perspective

Healthcare Quarterly, 2003
Effective communications with different stakeholders was critical for health systems everywhere during the worldwide SARS outbreak earlier this year. For Capital Health in Edmonton, Alberta, the health system was able to build on its past experiences in dealing with meningococcal outbreaks and its planning for a pandemic flu.

The NEC interferometric SAR system "NEC-SAR"

IGARSS '96. 1996 International Geoscience and Remote Sensing Symposium, 2005
The authors describe the Japanese "NEC-SAR" remote sensing system outline, and data processing, and the summary of evaluation of interferometric images. This terrain imaging radar system is installed in a Cessna 208 aircraft and is capable of producing topographic images.

Multistatic Scenarios for a GPS SAR System

IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008
This paper presents research results in space-surface multistatic synthetic aperture radar (SS-MSAR) with non-cooperative GPS satellites. The effect of the system's geometry is investigated. We will show that in SS-MSAR, the spatial resolution depends on the geometry of the system, i.e.

A three dimensional SAR system on an UAV

2007 IEEE International Geoscience and Remote Sensing Symposium, 2007
Applications of small unmanned aerial vehicles (UAVs) have increased steadily over the past years. Applications are found in Earth observation, reconnaissance, monitoring, and surveillance missions using imaging systems. The big advantage of radar sensors is their all-weather capability.

Potentials of a compact polarimetric SAR system

2010 IEEE International Geoscience and Remote Sensing Symposium, 2010
The goal of this study is to show the potential of a compact-pol SAR system for vegetation applications. Compact-pol concept has been suggested to minimize the system design while maximize the information and is declined as the π/4, π/2 and hybrid modes.
