The REV method based on power measurement can avoid the phase measurement, so the calibration can reach a high stability especially in high frequency. A modified method that can significantly reduce the phase-shifting error in REV method is presented in this paper. It is verified that increasing the bits of phase shifter and measuring states can reduce the effect of such error and improve the calibration...
A new combined REV calibration method for large phased array antenna is presented in this paper. This method is based on power measurement, so the measurement can reach a high stability in high frequency. It can also improve the calibration accuracy and efficiency at the same time, especially in large phased array antenna. Simulation results testify the correctness of this new method.
Large APAA (active phased array antenna) contains hundreds of elements and the performance of an APAA will degrade over time as a result of changes mainly in the solid-state components. For airborne and satellite-borne APAA applications, ground-based calibration sources may be difficult or impractical to implement due to the constraints of volume and resources. In this paper, a novel self-calibration...
There could be all kinds of errors in the space-borne active array antenna because of its features such as highly integrated, complex configuration, strong mutual coupling and other factors. Obviously, these errors will affect the performances of array antenna. To address this issue, various methods have been proposed to calibrate these errors to guarantee the performance of the entire array.
