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.

在这项研究中，我们开发了一个可运输的S波段边界Layr雷达（BLR）系统，该系统较小，光线和便携。 S频段BLR由天线单元，发射机/接收器单元，数据采集单元和数据处理单元组成。・天线单元是直径为1 m的相位阵列天线，增益为26 dbi。比率小于20％。・数据采集单元主要由A/D转换器和DSP（数字信号处理器）提示组成。它将接收到的信号转换为数字数据，并执行脉冲压缩和相干集成的解码。为了实时执行这些计算，数据采集单元并行使用八个DSP提示。・数据处理单元由工作站组成，控制雷达并实时执行数据处理。通过使用工作站，可以使用无人操作，并且“快速外观”的观察数据也可以与观测值同行。观察的开始和停止可以使用GUI（图形用户界面）进行操作。我们在Shigaraki MU观察时与MU雷达同时进行了观察。从与MU雷达的观察结果相比，我们证实了S波段BLR可以观察到风。
