SOLUTION: Active modules 120, 130 supply two signals received from array antennas 100, 110 to a power combining portion 140 to combine them. A frequency converter portion 150 supplies a bias from a signal distribution/detection portion 160, and converts a satellite signal into a signal of a frequency band lower than that. The distribution/detection portion 160 distributes the satellite signal received from the converter portion 150, supplies it to a rotary joint 190, receives a tracking signal selection signal from a satellite tracking portion 170 for detecting a tracking signal, and detects the strength of a signal of a desired channel.

Abstract: The present invention relates to a method and a device for phase measurement for microwave image diagnosis. The disclosed method for phase measurement comprises the steps of: measuring a phase value of microwaves received by N receiving antennas; calculating a phase difference value of the microwaves received by the adjacent receiving antennas among the N receiving antennas; and acquiring unwrapped phase data by selectively adding and subtracting the measured phase value according to the calculated phase difference value. Therefore, since an unwrapped phase can be easily measured even if a narrowband microwave transceiving unit is configured using a single frequency when acquiring the unwrapped phase data, the microwave transceiving unit can be configured at low costs, thereby reducing manufacturing costs. Since a single frequency, not a plurality of frequencies, is measured, measurement time is reduced. Since a measurement frequency band can be increased, resolution characteristics of a microwave image diagnostic device can be improved.
Abstract translation: 本发明涉及一种用于微波图像诊断的相位测量方法和装置。 所公开的相位测量方法包括以下步骤：测量由N个接收天线接收的微波的相位值; 计算由N个接收天线中的相邻接收天线接收的微波的相位差值; 并通过根据计算出的相位差选择性地加减法测得的相位值来获取展开的相位数据。 因此，即使在获取展开相位数据时使用单频率配置窄带微波收发单元，也能容易地进行展开的相位测量，所以能够以低成本构成微波收发单元，从而降低制造成本。 由于测量单个频率，而不是多个频率，所以测量时间减少。 由于可以提高测量频带，因此可以提高微波图像诊断装置的分辨率特性。
