It is a 4m diameter antenna operating a feeder of the type of broadband ‘Cavity Backed’ to observe the emission spectrum of solar flares in the canonical band emission (from 2 to 40 GHz). Measures the emission of circularly polarized radiation from solar flares in its two modes. The primary detection is used to solve the inverse problem of determining the spectrum of particles, which were accelerated during abrupt burst of the blast energy from the photon spectrum. Provides basic parameters related to the spread of this disorder in interplanetary space until his arrival on Earth. The trial is expected to generate 250 MB / day and similarly to the previous case is compatible with a standard for transmission over the Internet anywhere at INPE. You also need a part-time operator for the ongoing maintenance of the instrument.
