通信研究实验室（CRL）开发了一种新的C波段（5340 MHz）多参数多普勒雷达系统，具有双基地多普勒雷达网络。其目的是建立下一代降水观测技术，用于气象和水文应用，如天气预报和预测洪水的径流分析。这种新雷达被命名为COBRA（CRL冲绳双基地极化雷达）。该系统的天气目标是台风、锋面降水、副热带中尺度降水和晴空湍流。使用两个发射机（速调管）单元来观察降水粒子的偏振特性。每个脉冲的传输偏振是从六种可能的偏振中选择的。返回信号由两个接收器同时测量，一个用于水平极化，另一个用于垂直极化。
Communications Research Laboratory (CRL) has developed a new C-band (5340-MHz) multi-parameter Doppler radar system with a bistatic Doppler radar network. The purpose is to establish the next-generation technology of precipitation observation for meteorological and hydrological applications, such as weather forecasting and run-off analysis for predicting floods. This new radar is named COBRA (CRL Okinawa Bistatic polarimetric RAdar). The weather targets of the system are typhoons, Baiu-frontal rainfall, meso-scale precipitation in subtropical zones, and clear-air turbulence. Two transmitter (klystron) units are used for to observe the polarization characteristics of precipitation particles. The transmission polarization for each pulse is selected from six possible polarizations. The return signal is measured simultaneously by two receivers, one for the horizontal polarization and the other for the vertical polarization.
