Detect phase shifter module of array antenna using the sun

The Sun is an emission source which has a wide spectrum and high-energy flow, it can be used as a calibration source; The phase shifter module is the minimum detection unit of the phase array antenna, the paper propose two evaluation parameters, which by receiving the energy of the solar radio, then compare the receiving power of each channel, that can get the two evaluation parameters, those two parameters shows the performance of each phase shifter module; Finally, verify the effectiveness of the method by a simulation experiment.
