Abstract

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.
