Microwave radar imaging using a solid state spintronic microwave sensor
Abstract
In this paper, we demonstrate that spintronic microwave sensors have the capability to perform microwave imaging. The detection of the amplitude and phase of a scattered microwave signal over a wide frequency band allows this technique to determine the time delay of a microwave signal scattered by the target. Combining microwave radar techniques and a wavefront reconstruction algorithm with a spintronic microwave sensor in circular trajectory, the reconstructed images of targets are obtained. The reconstructed images clearly indicate the targets' positions even when the targets were immersed in a liquid to simulate an inhomogeneous tissue environment. Such a technique provides a promising approach for microwave imaging, with the potential for biomedical applications.
