In realizing geostationary high throughput satellite (HTS), building flexible beam adapting to change of communication traffic is needed. Digital beam forming (DBF) has advantages of flexibility of beam steering and high integration. The R&D project focused on developing receiving DBF with Ka-band is ongoing. In DBF system, it is important to calibrate the gain, phase, and delay for each antenna element. In this chapter, we propose a method of calibration using digital processing on the satellite and ground station. The crosscorrelation vector between elements calculated in digital processor on the satellite is useful for detecting error of the gain, phase, and delay for each antenna element. These errors will be corrected with setting the correction coefficient to the satellite, which is calculated at the ground station with a cross-correlation vector transmitted from the satellite.
