摘要：
This paper introduces a W-band phased electromagnetic surface radar system. This phased electromagnetic surface works at 92∼96 GHz and is manufactured with general PCB technology and processing accuracy requirements. The appropriate unit design makes the DC bias voltage of each PIN diode on the phased electromagnetic surface controlled for the current reversal purpose at a low cost and portability. A 180° phase shift of the unit cell can be provided as the current direction on the unit cell is reversed. Beam scanning in different directions can be formed when inputting the right spatial codes. This transmission type phased electromagnetic surface with the ability of beam scanning is used as the receiving antenna of the radar system. This paper presents a W-band phased electromagnetic surface radar system and its manufacture and measurement results, which are fundamental to further research of precision guidance, target identification, and imaging. © 2021 Institute of Electronics Chinese Academy of Sciences.
