本文介绍了一个在圣安德鲁斯大学开发的相干24 GHz雷达系统的硬件设计，以获得微多普勒数据。该系统基于ADI公司的EV-RADAR-MMIC 2评估板，该评估板基于由三个集成电路组成的芯片组：一个双通道发射器、一个四通道接收器和一个小数N分频频率合成器。该评估板与许多其他组件相结合，可实现与基于PC的数据采集卡的一致操作，并提高输出功率以增加工作范围。三个相同的定制光滑壁圆锥喇叭天线发射和共和交叉极化接收信号的设计和建造的雷达系统。结果表明，这些高增益（24.5 dBi）天线的性能非常符合设计模拟。最后，包括人，鸟和无人机的微多普勒数据的现场试验结果显示，以验证系统的性能。
This paper presents the hardware design of a coherent 24 GHz radar system developed at the University of St Andrews to obtain micro-Doppler data. The system is based on the Analog Devices EV-RADAR-MMIC2 evaluation board which is based around a chipset of three integrated circuits: a two channel transmitter, a four channel receiver and a fractional-N frequency synthesizer. The evaluation board is combined with a number of other components to enable coherent operation with a PC-based data acquisition card and to boost the output power to increase the operational range. Three identical custom-made smooth-walled conical horn antennas for transmit and co- and cross-polar receive signals were designed and built for the radar system. It is shown that the performance of these high gain (24.5 dBi) antennas agrees extremely well with the design simulations. Finally, field trial results comprising human, bird and drone micro-Doppler data are shown to validate the system performance.
