摘要

本文介绍了一种开关超宽带微波成像阵列的设计。成像阵列被设计为交错双静态发射和接收阵列，以提供被成像样品的最佳覆盖。该阵列采用宽带维瓦尔第天线作为阵列单元。为了满足合成孔径成像的要求，该阵列进行了元件间距优化设计。介绍了该阵列的标定过程和实际应用。

UWB microwave imaging array for nondestructive testing applications

This paper presents the design of a switched ultrawideband (UWB) microwave imaging array. The imaging array is designed as an interlaced bi-static transmit and receive array in order to provide optimal coverage of the sample being imaged. The array utilizes wideband Vivaldi antennas as the array elements. The array is designed for optimal spacing between its elements to satisfy the requirements of synthetic aperture imaging. The calibration procedure and utility of this array is presented.
