Abstract

PURPOSE: To accurately measure the spectrum distribution of receiving waves, by branching signals emitted from a station drawn from the carrier waves of incoming waves, and using the self and mutual power spectrum density of each low-frequency signal obtained.
CONSTITUTION: Oscillation waves from klystron 1 are projected to plasma 4 from an antenna 3, and the penetrated waves are received by means of an antenna 5 and supplied to mixers 14, 15 through a magic T 6. One portion of the output of an oscillator 1 is fed as signals emitted from a station of the mixers 14, 15 through a directional coupler 7 and a 90° phase shifter 11. When the self-power spectrum density of low-frequency signals V1(t), V2(t) gained from each mixer is severally G11(f),G22(f) and mutual power spectrum density is respectively G12(f), G21(f), power spectrum density S+(f), S+(f) in a wave zone at the upper side and a wave zone at the lower side are acquired by a formula I.
