Abstract
The frequency dependence of the antenna voltage patterns and the amplitude and phase errors calibrated by external noise sources is analyzed and verified by simulations and experiments, an improved calibrated method using external single signal is proposed to be an alternative to the external noise sources, and the simulations and experiments show that the improved method can mitigate the effect of the frequency dependence of that can be as an alternative in the calibration of aperture synthesis radiometer.
