It is based on the information from two harmonic frequencies of Flourier Transformation of longitudinal charge distribution. We select 500MHz and 3GHz as working frequency and the system consists of power splitters, band-pass filters and a mixer. Raw data are acquired by a digital oscilloscope and analyzed by MATLAB code. The system has been calibrated by Streak Camera in single-bunch experiment environment with bunch charge from 0.23nC to 6.05nC. The paper also shows bunch length synchronous oscillation phenomenon during injection period.
