Abstract

The paper proposes a method for high resolution range imaging at millimeter wave frequencies (85 GHz to 100 GHz) based on model-based compressed sensing (CS). A detailed description of the underlying CS-theory, the experimental setup and radar sensor are presented along with experimental results for one-dimensional range imaging. The proposed method is based on motorized reference measurements, which form the dictionary matrix for subsequent CS-processing. These reference measurements are tested against measurements from a glass fiber reinforced polymer (GFRP) component. A comparison of the CS-processed data to a classical Fourier-domain analysis revealed superior ranging performance of the CS-approach at the expense of a higher signal processing load.
