RESEARCHS

The research and education activities in Microwave Remote Sensing Laboratory, Center for Environmental Remote Sensing, Chiba University, Japan covers research themes as below. This laboratory promotes the education and research to develope the internationally technologies and sciences. We 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 develope original methods or sensor during the courses.

Global vegetation mapping using synthetic aperture radar images
This laboratory proposes many methods to monitor the landcover of earth surface by using microwave (L, C, and X bands) to know the characteristics of vegetation, especially interferometric and polarimetric SAR techniques are employed to retrieve the tree informations, including 3D tree mapping.
Mapping of snow area in tropical area
This laboratory employs the polarimetric - interferometric SAR (Pol-InSAR) and develop original methods to monitor the snow cover in tropical area, especially at Papua island. This research is focused to retrieve the correlation between snow change and global warming.
Natural resources mapping using SAR technique
The main objective of this research is to mapping the natural resources by interpret the earth surface using synthetic aperture radar. We collaborate with many agency relating the mineral exploration to map the global natural resources, especially in Asian countries. The multi polarization microwave is employed to find the accuracy natural resources map. This result is also used to develop new sensor in our laboratory.
Three dimension city mapping using old maps and satellite images
This important research is done to build 'Asian spatial database program' using remote sensing and GIS technique. This program is established to promote the Asian infrastructure, especially the spatial information infrastructure. In this program, we collect the old maps as reference to make scale 1:50 000 maps whole of Asian countries.
Development of high resolution - ultra wide band SAR (HiRes-UWB-SAR)
This laboratory developes many types of next generation sensors for earth surface monitoring.
We propose the synthetic aperture radar that has high resolution and multi bands. In the future, this sensor could be employed to retrieve detail information of earth surface, including natural resources or minerals, vegetation, city mapping, snow area etc.
Development of 3D Weather Radar
In this research, we develop original 3D Weather Radar that works in 5 GHz and 13 GHz. This radar will be installed in many sites around Asian countries to profiling the cloud to investigate the phenomenon in hydrosphere.
Development of microstrip antennas for SAR and mobile satellite communications
This is an unique research theme in this laboratory. In this research, we develop many types of original shape of microstrip antennas for SAR and mobile satellite communications. Recently, we received many awards and research grants relating this research.
