Title: THREE-DIMENSIONAL MICROWAVE IMAGING SYSTEM AND METHOD
Abstract:
Disclosed are a three-dimensional microwave imaging system (100) and method. The system comprises a signal transceiving module (10), at least two antenna array modules (21-2n), a switch array module (30), a mechanical scanning module (40) and a data processing module (50), wherein the switch array module (30) is used for controlling switching on and switching off states of each transmitting antenna unit and each receiving antenna unit in the antenna array modules (21-2n); the mechanical scanning module (40) is used for controlling the simultaneous rotation of all the antenna array modules (21-2n) around a pre-set target in a pre-set rotation direction; during the process of rotation of the antenna array modules (21-2n), the signal transceiving module (10) transmits an electromagnetic wave to the pre-set target by means of the antenna array modules (21-2n), receives an electromagnetic wave reflected back by the pre-set target, and converts the reflected electromagnetic wave into a simulated echo signal; and the data processing module (50) processes the simulated echo signal to obtain three-dimensional image data of the pre-set target. By means of using at least two antenna array modules (21-2n) to scan a pre-set target, echo data of the pre-set target can be acquired fast, thus realising fast imaging of the pre-set target.
