Outline of Final Research Achievements

We studied several techniques for intelligent plasma wave receiver to measure space plasma environment around the Earth using formation-flying satellites.
First we made a feasibility study to propose a co-operational measurements using inter-satellite communication system. We proposed algorithms for selection of optimum observation mode adjusting dynamic change of Earth’s magnetosphere. We also developed signal processing modules on FPGA such as sub-band compression of waveforms to achieve real-time data processing in a miniaturized receiver. Finally we demonstrated new techniques for direction finding of plasma waves and estimation of ion constituents in the Earth’s plasmasphere.
