Development of a transportable S-band boundary layr radar

在这项研究中，我们开发了一个可移动的S波段边界雷达（BLR）系统，该系统体积小、轻便、便携。天线单元、发射器/接收器单元、数据获取单元和数据处理单元的S波段BLR组件。天线单元是一个相位阵列天线，直径为1米，增益为26分贝。发射机/接收机单元具有发射频率为3.05千兆赫的性能，峰值功率为500瓦，带宽为10兆赫，工作速率低于20%。A/D转换器和DSP （数字信号处理器）的数据获取单元主要考虑因素。它转换为接收信号到数字数据，并对脉冲压缩和相干积分进行解码的性能。如果要在实时中执行这些计算，则数据采集单元在并行中使用8个DSP提示。数据处理单元由一个工作站控制，雷达控制，并在实时进行数据处理。通过使用工作站，未经授权的操作可用，“快速查看”的观测数据也可在并行观测中使用。启动和停止的观察可以通过使用GUI （图形用户界面）来操作。我们使用MU radar at the Shigaraki MU observatory。从MU Radar的观测结果比较，我们确认S-Band BLR可以观察到的窗口。

In this study, we have developed a transportable S-band boundary layr radar (BLR) system which is small, light, and portable. S-band BLR consists of an antenna unit, a transmitter/receiver unit, a data acquisition unit, and a data processing unit.・The antenna unit is a phased array antenna with a diameter of 1 m and a gain of 26 dBi.・The transmitter/receiver unit has the performance of a transmitted frequency of 3.05 GHz, a peak power of 500 W,a band width of 10 MHz, and a duty ratio of less than 20%.・The data acquisition unit mainly consists of A/D converters and DSP (Digital Signal Processor) tips. It converts received signal into digital data, and performs decoding of pulse compression and coherent integrations. In order to perform these calculation in real-time, the data acquisition unit uses eight DSP tips in parallel.・The data processing unit consists of a workstation, controls the radar, and performs a data processing in real-time. By using the workstation, unmanned operation is available, and 'Quick Look'of observation data is also available in parallel with observations. Start and stop of observations can operate by using GUI (Graphical User Interface).We conducted simultaneous observations with the MU radar at the Shigaraki MU observatory. From comparison with the observation results by the MU radar, we confirmed S-band BLR can observe winds.
