相控阵发送装置
摘要：
相控阵发送装置设有：通过耦合器单元(161、162)抽取多个发送分支(101、102)的发送输出，对抽取出的各发送分支的信号电平分别进行检波的分支检波单元(121、122)；以及对由信号合成单元(110)合成来自抽取出的两个分支的输出后得到的输出进行检波的合成检波单元(130)，比较分支检波单元(121、122)的输出电平而检测并校正振幅误差，并根据合成检波单元(130)的输出电平来检测并校正相位误差。
摘要（英）：

A phased array transmission device is provided with: branch detection units (121, 122) which extract the transmission output of a plurality of transmission branches (101, 102) by means of coupler units (161, 162), and detect the signal level of each of the transmission branches subjected to extraction; and a synthesis detection unit (130) which detects the output of a signal synthesis unit (110) which synthesizes output from the two transmission branches subjected to extraction. Amplitude errors are detected and corrected by comparing the output level of the branch detection units (121, 122), and phase errors are detected and corrected by using the output level of the synthesis detection unit (130).
