Decimeter high resolution solar radio spectroscope

High sensitivity (8 – 0.8 s.f.u.), high time (100 msec), frequency (300 – 3000) KHz resolution decimeter spectroscope operating at present in the frequency range of (1600 ± 50) MHz has been put into operation in Sao Jose dos Campos at the National Space Research Institute, Brazil. Finally, this spectroscope will be operated over a frequency range of (200 – 2500) MHz. However, in high resolution mode, it will be operating over a frequency range of (fs ± Af), ( Af will be selected in the range of (50 – 500) MHz or as desirable), where fs is the frequency selected in the entire range of band. At the same time, the entire frequency band will be monitored with low resolution mode. Initial observations of this spectroscope at (1600 ± 50) MHz, the details of spectroscope and future development plans (up to 1992) are presented.
