| Abstract(in English) | Engineering Test Satellite VIII(ETS-VIII)was equipped with the large deployable reflector antenna(LDRA)for mobile communications with the physical size of 19m by 17m, which is one of the largest size for communications satellite. This paper describes the electrical performances of that antenna. We measured signal level of radio wave from LDR at some ground receiving stations. This result is daily variation of receiving level and precipitous variation during the satellite-eclipse. We considered this phenomenon was caused by thermal distortion of reflector. We made experiment to correct the antenna beam position and measured the receiving level for improvement of this variation. |
