Foreword to the Special Issue on Advances in SAR and Radar Technology

Abstract

1]. There 163 papers were presented to over 240 attendees with worldwide 17 exhibiting companies. It was a very exciting activity [2] held by IEEE GRSS All Japan Chapter [3] and the Institute of Electronics, Information, and Communication Engineers (IEICE) Electronics Society.APSAR covers a wide variety of SAR and radar related topics including SAR applications, analysis techniques, signal processing, and SAR system design and concepts. In APSAR 2013, "Disaster Monitoring" was the main theme, providing the attendees with an opportunity to think about how each of us can contribute through SAR technology to overcome the hardships after disasters.To further promote research activities in this and relevant areas, IEEE JSTARS planed to publish this Special Issue on Advances in SAR and Radar Technology. The scope of this Special Issue is then identical with that of APSAR 2013 Tsukuba, which ranged over the six topical fields, namely:A. Disaster Monitoring: Contribution of SAR remote sensing on the Great East Japan Earthquake, ALOS2 projects for prediction, mitigation, and restoration, SAR applications for various disasters, and present and future SAR systems and missions in Asia-Pacific region; B. SAR Applications: Land use and land cover, soil and vegetation applications, atmosphere and ocean observation, snow and ice, and coastal and wetlands; C. Analysis Techniques: Electromagnetic modeling, InSAR and high-resolution SAR, POL and POLInSAR, and Bistatic SAR; D. SAR Signal Processing: High-resolution SAR processing, SAR/GMTI/STAP and change detection, image filtering, correction and enhancement, and SAR/ISAR signal processing; E. SAR Systems and Sensors: Spaceborne and airborne SAR systems and missions, advanced and innovative SAR concepts and modes, ground-based systems, and calibration; F. Radar Technology: Radar components and subsystems, antenna technology and adaptive arrays, UWB, GPR, bio-medical imaging radar systems, and automotive radar.

Real-Time SAR Imaging Based on Reconfigurable Computing

“…Further, the application modes have been upgraded from the original single-radar highresolution imaging to multi-mode multi-angle autonomous guidance, multi-radar cooperative precision imaging, and others. With fixed weight, volume, and power consumption of the load platform, the use of a single chip to complete real-time image processing establishes the basis and challenge for implementation of complex multi-mode new SAR systems [1][2][3][4][5][6][7][8].…”

An Efficient Dual-Channel Data Storage and Access Method for Spaceborne Synthetic Aperture Radar Real-Time Processing

“…It is a radar that uses the Doppler information generated by the relative motion between the radar platform and the detected target, and uses signal processing method to synthesize a larger antenna aperture [1][2][3]. As it can penetrate clouds, soil and vegetation, it has become more and more widely used in many important fields [4][5][6]. Recent publications have reviewed the applications of satellite remote sensing techniques for hazards manifested by solid earth processes, including earthquakes, volcanoes, floods, landslides, and coastal inundation [7][8][9].…”

Spaceborne synthetic aperture radar imaging mapping methodology based on FPGA‐DSP hybrid heterogeneous architecture

“…A spaceborne synthetic aperture radar (SAR) works all‐weather day‐night and has the ability to image vast area at a high resolution [1]. As one of the important means of space‐to‐Earth observation, SAR plays an important role in disaster emergency response, environmental monitoring, resource exploration and geographic information access [2–4]. Recent publications have reviewed the applications of satellite remote sensing techniques for hazards manifested through solid earth processes, including earthquakes, volcanos, floods, landslides, and coastal inundation [5–7].…”
