Abstract: Synthetic Aperture Radar (SAR) is well-known as a multi-purpose sensor that can be operated in all-weather and day-night time. In this research, we propose Circularly Polarized Synthetic Aperture Radar (CP-SAR) or Elliptically Polarized Synthetic Aperture Radar (EP-SAR) to retrieve the physical information of land surface and disaster monitoring. The sensor is designed as a low cost, light, low profile configuration to transmit and receive left-handed circular polarization (LHCP) and right-handed circular polarization (RHCP). For this purpose, we also develop unmanned aerial vehicle (UAV) for ground experiment of this sensor. The main mission of CP-SAR is to hold the basic research on elliptically polarized scattering and its application developments. In the basic research, we will investigate the elliptical (including circular and linear polarizations) scattering wave from the land surface, generation of axial ratio image (ARI), ellipticity and tilted angle images etc. CP-SAR sensor transmits only one polarization, RHCP or LCHP, then this sensor will receive RHCP and LHCP scattering waves simultaneously. The image is employed to investigate the relationship between the physical characteristics of vegetation, soils, snow etc. The image of tilted angle as the response of land surface also will be extracted to mapping the physical information of the surface, i.e. geological matters, contour, snow-ice classification, vegetation characteristics etc. In this presentation we will introduce our progress on development of CP-SAR sensor, unmanned aerial vehicle and microsatellite, including ground station and applications of SAR image processing to monitor environmental change in Asian region, especially Malay Peninsula.

Speaker’s Biography: He was born in Sulaiman Special Force Airbase — Indonesian National Air Force Hospital, Bandung, and West Java, Indonesia in 1970. He received the B.Eng. and M.Eng. degrees in Electrical and Computer Engineering from Kanazawa University, Japan in 1995 and 1997, respectively (Subsurface Radar Systems) and the Ph.D. degree in Artificial System Sciences (Applied Radio Wave and Radar Systems) from Chiba University, Japan in 2002. From 1990 to 1999, he was a Researcher with the Agency for Assessment and Application of Technology, Jakarta. He was with the Center for Frontier Electronics and Photonics (Venture Business Laboratory), Chiba University, Japan as a Lecturer (Post Doctoral Fellowship Researcher) from 2002 to 2005. He was an Associate Professor (permanent staff) at the Center for Environmental Remote Sensing (CEReS), Chiba University from 2005 to 2013, then Full Professor (permanent staff) at the same center from 2013 to now, and as a Visiting Lecturer/Professor in many Universities. His main interests are theoretically scattering microwave analysis and its applications in microwave (radar) remote sensing, especially synthetic aperture radar (SAR) and subsurface radar (VLF) including DInSAR and PS-InSAR, analysis and design of antennas for mobile satellite communications and microwave sensors, development of microwave sensors including SAR for Unmanned Aerial Vehicle (UAV) and microsatellite development. He manages Josaphat Microwave Remote Sensing Laboratory (JMRSL), Center for Environmental Remote Sensing (CEReS), Chiba University, Japan. His laboratory promotes the education and research to develop the internationally technologies and sciences. He always encourages the undergraduate and postgraduate students to know the microwave phenomenons and to be familiar with the interaction between microwave and natural matters (i.e. vegetation, artificial materials, earth surface, snow), therefore they could develop original methods or sensor during studying in the courses.
