The application of REV method for missile-borne phased array antenna calibration

There are some significant drawbacks when traditional REV method is used for missile-borne phased array. In this paper, auxiliary antenna is applied in near field. The group REV method is created to overcome the disadvantage of too weak total power variety when single array element channel phase shifter changes. So the improved REV method is more suitable for missile-borne phased array antenna calibration. The results of simulation also show that this method can improve the calibration accuracy.
