月面低周波電波天文台観測システムの検討

摘要

Low frequency radio wave of below 30 MHz is one of the last frontiers for astronomical observation because of theinterference by the terrestrial ionosphere and the lower angular resolution of a single element antenna. We proposethe first-step observation system to display the technical and astronomical properties by a 25 to 30 MHz-band radiointerferometer composed by the antenna on the lunar polar area and terrestrial observatory. We examine the design ofthe antenna on the lunar surface and the mechanism for its expansion. The design of data acquisition and handlingsystem, and the argument for the comparison with the formation flight system are also presented.
