SSRE 

The Center for Space Science and Radio Engineerig conducts research to deepen our understanding of various electromagnetic environments from outer space and the upper layers of the Earth to the places where we live and work, based on the measurement and modeling of electromagnetic waves. Information on each laboratory will be updated as it becomes available.

CONTENTS

Through electromagnetic observations and modeling from the ground and satellites, we aim to understand the electromagnetic environment of the earth and space (science) and to monitor and predict natural disasters caused by earthquakes, torrential rains, tornadoes, and solar activity (engineering), in order to realize a safe and secure society. 


XIAO LAB. 

http://www.emclab.cei.uec.ac.jp/

CONTENTS

Our research interests include electromagnetic environment, EMC (Electromagnetic Compatibility), electromagnetic field visualization, microwave and millimeter-wave transmission circuits, and computational electromagnetics. Specifically, we are conducting research on the following points Research on electromagnetic wave visualization. Research on EMC modeling, SI and PI analysis. We are analyzing crosstalk between lines and clarifying coupling mechanisms using numerical analysis software developed in our laboratory and commercial electromagnetic field simulation software.


KOJIMA LAB. 

CONTENTS

We study transmission technologies (modulation and demodulation and channel coding) for digital wireless communication systems such as satellite and mobile communications. We aim to establish transmission technologies that can transmit more data, with less energy, and with fewer errors, through both computer simulations and theoretical investigations.


ANDO LAB.

CONTENTS

Our research interests include “electromagnetic field analysis”. We study efficient calculation methods for electromagnetic wave propagation, antenna analysis, and simulation of radio wave propagation in space. Research topics range from the science of simulating unknown electromagnetic phenomena to the engineering of antenna design to meet required specifications.

CONTENTS

The 21st century is the era of advanced utilization of space: space communications by communications and broadcasting satellites, earth environment measurements by meteorological and geodetic satellites, navigation using GPS satellites, the International Space Station (ISS) for the creation of new science and technology, and extra-vehicular space activities to maintain the ISS. In order to achieve these goals, it is essential to have a precise understanding of the Earth's upper atmospheric environment, including space, in order to deploy and maintain space systems safely, to ensure stable links with the ground, and to predict safety during extravehicular activities. In particular, a detailed understanding of the dynamics of the ionosphere, a layer of ionized atmosphere extending from an altitude of 80-500 km, is important because it is the area over which the ISS and many polar-orbiting satellites fly and has a significant impact on radio propagation for satellite communications and satellite positioning. To meet this demand, we are engaged in various measurement projects to elucidate the physical processes that govern the dynamic changes in the Earth's upper atmospheric environment.. 


SAKAI LAB. 

CONTENTS

Our laboratory develops receivers for radio telescopes and conducts observational research using them. The main goal of our research is to understand the mechanism of stellar birth. We are conducting observations not only with existing instruments but also with new instruments developed by ourselves and mounted on large radio telescopes.


TSUDA LAB. 

http://ttt01.cei.uec.ac.jp/

CONTENTS

We explore the science of the Earth's atmosphere and outer space using remote sensing technology based on light and radio waves. We are also engaged in engineering of observation techniques and instruments, such as aurora observation using a high-sensitivity camera and atmospheric observation using lasers.

CONTENTS

Of the 22 events that have been designated as severe disasters by the Cabinet Office in the past five years, 19 were disasters caused by meteorological phenomena, excluding the Nagano and Kumamoto earthquakes and the Hokkaido earthquake. Most of these disasters were caused by landslides and floods due to rainfall, such as typhoons and torrential rains, and the construction of highly accurate rainfall observation systems and their disaster prevention measures are urgently needed in the social context. Our laboratory is developing next-generation meteorological radar technology and disaster forecasting technology based on meteorological knowledge for the purpose of disaster prevention.
