Microwave Imaging Based on Wideband Range Profiles

In this paper, the microwave images of two-dimensional section of multiple objects are formed by using the wideband range profiles of the target. Scattered electric field is obtained by the designed two-dimensional imaging system and Fourier transformed into the highly-resolved range profiles while the target rotates. A filtered backprojection (FBP) algorithm is implemented to form the image from the space domain range profiles. Images of multiple cylindrical rods from both numerically simulated and measured data indicate that the approached imaging scheme can achieve high dynamic range and can be potentially implemented for biomedical imaging detections.
