Title:
放射パターン制御装置及び中継器
Document Type and Number:
Japanese Patent JP7257185
Kind Code:
B2
Abstract:
To provide a radiation pattern control device and a repeater that control a digital phase shifter provided in the repeater so as to reliably suppress burst errors on the receiving device side due to the transition of a radiation pattern in the repeater for transmission signals transmitted using satellite transmission lines or terrestrial transmission lines.SOLUTION: A radiation pattern control device 13 according to the present invention includes a radiation pattern calculation unit 131 that calculates a desired radiation pattern, a stepwise output phase determination unit 133 that determines the number of transitions for stepwisely transitioning to the output phase of a radiation element array 231 in a repeater 2 required for transitioning from the current radiation pattern to the desired radiation pattern, and a command generation transmission unit 136 that generates a command for stepwisely controlling the phase shift amount of the digital phase shifter on the basis of the number of transitions and transmits the command to the repeater 2. The repeater 2 of the present invention includes a digital phase shifter controlled by the radiation pattern control device 13.SELECTED DRAWING: Figure 1
