研究了单边带混频器作为多普勒雷达传感器目标模拟器的应用。SSB混频器调制多普勒雷达发射的连续波射频（RF）信号，类似于移动目标。为了证明所提出的目标模拟器的有效性，一个真实的人类目标执行手势的响应进行了仿真使用的目标模拟器。的人的手势和模拟器生成的手势的频谱进行了比较的性能评估。一个5.8 GHz的原型提出的目标模拟器和获得的实验结果的文件。
This article presents a study on employing a single-sideband (SSB) mixer as a target simulator for Doppler radar sensors. The SSB mixer modulates the continuous-wave radio frequency (RF) signal transmitted by the Doppler radar, similar to a moving target. To prove the effectiveness of the proposed target simulator, the response of a real human target performing a hand gesture is emulated using the target simulator. The spectrogram of the human hand gesture and the simulator-generated gesture have been compared for performance evaluation. A 5.8-GHz prototype of the proposed target simulator and the obtained experimental results are presented in the paper.
