摘要： In a phased-array antenna apparatus of this invention, one of the transmit/receive modules of each of radiators is set in a receiving operation state in accordance with a control signal from an arithmetic processing unit. An RF reference signal from an exciter is radiated in the air from a reference antenna and received by the transmit/receive modules in the receiving operation state. Thereafter, the signals are frequency-converted by the receiver, and element data are extracted from the signals by a beam forming section. The arithmetic processing unit detects the phase and amplitude data of the reception signals from the transmit/receive modules on the basis of the element data, and compares the detected data with the past phase and amplitude data of the transmit/receive modules, thereby calculating correction data and weight data for the transmit/receive modules.

摘要： An antenna apparatus is provided with two parabolic antennas which are attached to an X-axis and adapted to independently rotate about the X-axis. The X-axis is supported between both ends of a support rail in the shape of a semicircular arc to pass through the center of the arc. The support rail is adapted to slide and is thereby permitted to rotate about the central axis of the arc as a Y-axis. The support rail is placed on a rotating base 13 adapted to rotate about a Z-axis. The entire apparatus is covered with a radome. Each of the parabolic antennas is therefore permitted to rotate about each of the X, Y and Z-axes. By controlling each axis driving mechanism according to the locations and orbits of two satellites, each of the parabolic antennas is permitted to track a respective one of the satellites.
摘要翻译：天线装置设置有两个抛物面天线，其附接到X轴并且适于围绕X轴独立地旋转。 X轴支撑在支撑轨道的两端之间，以半圆弧的形状穿过弧的中心。支撑轨适于滑动，从而允许围绕弧线的中心轴线作为Y轴旋转。支撑轨道放置在适于围绕Z轴旋转的旋转底座13上。整个设备被天线罩覆盖。因此，每个抛物面天线被允许围绕X，Y和Z轴各自旋转。通过根据两颗卫星的位置和轨道控制每个轴驱动机构，允许每个抛物面天线跟踪相应的一颗卫星。
