本文首次对超高频波段中高层大气雷达(日本茂垣天文台)在频率分集条件下的距离成像技术性能进行了评价。这是通过在2015年6月1日至2015年6月14日进行的Shigaraki无人机雷达实验运动期间检测在雷达附近操作的无人机(UAV)来完成的。在这次致力于使用DataHawk无人机和MU雷达上的湍流传感器测量对流层下层精细尺度湍流和稳定性的活动中,MU雷达对小型无人机的探测为在单个硬目标存在的情况下评估距离成像技术提供了一个极好的机会。研究发现,距离成像以极好的精度(约10米的数量级)再现了飞机位置及其位移的忠实图像,为在稳定分层条件下通常从距离成像技术观察到的薄回波层及其垂直位移提供了额外的可信度。
For the first time, the performance of the range imaging technique of the very high frequency band middle and upper atmosphere (MU) radar (Shigaraki observatory, Japan), when using frequency diversity, is assessed. This is done by the detection of unmanned aerial vehicles (UAVs) operated near the radar during the Shigaraki UAV radar experiment campaign, carried out from June 1, 2015 to June 14, 2015. During this campaign devoted to the measurements of fine-scale turbulence and stability in the lower troposphere using the turbulence sensors on the DataHawk UAV and the MU radar, the detection of the small UAV by the MU radar provided an excellent opportunity for taking stock of the range imaging technique in the presence of a single hard target. It was found that range imaging reproduces a faithful image of the aircraft position and its displacements with an excellent accuracy (of the order of ~10 m), giving extra credence to the thin echo layers and their vertical displacements generally observed from the range imaging technique in stably stratified conditions.
