Research of Space Solar Power
Station/Satellite (SPS)
We study various researches for the SPS as follows ;
・ System
design of the SPS (in Japanese/international SPS research committees)
・ Development
of Phase Controlled Magnetrons for high efficient phased array
We have developed phase
controlled magnetron with cooker-type magnetron which is high efficient, low
cost and high power and have developedphased array with the PCM(SPORTS2.45, SPORTS5.8). Additionally,
we have developed phase and Amplitude Controlled Magnetron (PACM) and the PCM
for phase modulation.
・ Development
of high efficient phase array with semi-conductors
We develop high
efficient phased array for the SPS with company. It contains GaN FET and MMIC
phase shifter for 5.8GHz.
・ Research
of high accurate target detecting system with retrodirective
We have developed retrodirective
target detecting transmitter with asymmetric 2 pilot signals, and have
developed retrodirective target detecting transmitter without local oscillator.
We have also carried out some experiments of software retrodirective with new
algorism of target detecting.
・ Development
of rectenna (Rectifying Antenna)
We construct the theory
of rectenna array connection to increase efficiency of rectenna array. We also
developed high efficient rectenna in weak power or in high power microwave. Recently,
we have developed GaN diode for high power rectenna with
