The Modeling and Simulations of Low Noise Floor Solar Radio Receiver

ABSTRACT

In the field of solar radio, the high performance solar radio receiver which has high sensitivity, large dynamic range is necessary to observe the radio storm fine structure. The low noise floor solar radio receiver can meet the observation request. By the theory analysis of the radio storm receiver’s noise floor and combining with the characteristic of solar radio storm, the paper submits a method based on adding low noise amplifier(LNA) before receiver and decreasing the frequency resolution bandwidth(RBW) to lower the solar receiver noise floor. The paper gives the verification of the design method by means of the modeling and simulations. And the verified results comply with the design target.
