70-500 MHz radiospectrograph for solar observation
Abstract
Solar observations using a swept frequency radiospectrograph have been started at Hiraiso Solar Terrestrial Research Center, Communications Research Laboratory. This spectrograph covers a frequency range from 70 to 500 MHz with a band width of 1 MHz and is able to measure the polarization of solar bursts and their intensity. It consists of a 10 parabolic antenna with a pair of crossed logperiodic antennas as a primary radiator, an antenna controller, two spectrum analyzers as a receiver, and a digital data processing system. The spectrograph is controlled by a personal computer and observation is carried out automatically from sunrise to sunset everyday.
