本文介绍了一个16通道，C波段FMCW雷达相控阵接收机的实际实现成像流动雪崩的目的。该相控阵设计为30°视场，可完全覆盖雪崩轨迹。使用2A间距的重叠子阵列实现了完全填充的均匀线性阵列设计，并且具有16个元件，阵列的波束宽度为1.6°。相控阵列布置在三层PCB上，由于其较大的物理宽度（1.95 m），该PCB被分成四个面板。该阵列安装在塑料柱上，用螺丝固定在防水雷达罩的铝底座上，以提供机械强度。PCB和铝底座之间的无线电吸收材料可防止后瓣反射。PCB面板上的连续接地使用接地铜片桥来保持。相控阵的初步实验室测量表明，其性能符合预测。
This paper presents the practical implementation of a 16 channel, C-band FMCW radar phased array receiver developed for the purpose of imaging flowing avalanches. The phased array is designed for a 30° field of view to give full coverage of an avalanche track. A fully populated, uniform linear array design is achieved using overlapping sub-arrays of 2A spacing, and with 16 elements, the beamwidth of the array is 1.6°. The phased array is arranged on a three layer PCB that is split into four panels due to its large physical width (1.95 m). The array is mounted on plastic pillars screwed to an aluminium base in a watertight radome to provide mechanical strength. Radio absorbent material between the PCB's and the aluminium base prevent back lobe reflections. A continuous ground across the PCB panels is maintained using grounded copper sheet bridges. Initial laboratory measurements of the phased array show that its performance agrees well with predictions.
