Active millimeter wave three-dimensional scan real-time imaging mechanism with a line antenna array

Autor: Yu, Yang, Qiao, Lingbo, Wang, Yingxin, Zhao, Ziran

Active Millimeter wave (AMMW) imaging is of interest as it has played important roles in wide variety of applications, from nondestructive test to medical diagnosis. Current AMMW imaging systems have a high spatial resolution and can realize three-di
