Title:
MULTIPLE-TRANSMITTING MULTIPLE-RECEIVING ANTENNA ARRAY ARRANGEMENT FOR ACTIVE MILLIMETER WAVE SECURITY INSPECTION IMAGING, AND HUMAN BODY SECURITY INSPECTION DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2020/035023
Kind Code:
A1
Abstract:
Provided are a sparse multiple-transmitting multiple-receiving array arrangement (100, 200) for active millimeter wave security inspection imaging, and a human body security inspection device and a human body security inspection method. The multiple-transmitting multiple-receiving array arrangement (100, 200) comprises a set of transmitting antennas (t) for transmitting millimeter waves and a set of receiving antennas (r) for receiving millimeter waves reflected by a human body, wherein the transmitting antennas (t) are arranged along a first row; the receiving antennas (r) are arranged along a second row; the first row is parallel to and spaced apart from the second row; and more than two receiving antennas (r) are correspondingly arranged between two adjacent transmitting antennas (t). The arrangement can improve the data collection speed and the antenna unit utilization rate, and can also reduce the hardware complexity and improve the engineering practicability.
