Millimeterwave imaging with compressed sensing: Effects of modulation frequency and data type

Millimeter wave imaging is a promising field that can be used in many areas, primarily in defense and security. The lack of high-resolution two-dimensional imaging detectors that work in this band, as well as the cost of measurements in this frequency band being high, make single-pixel imaging configuration attractive. Data acquisition with compressed sensing is preferred to reduce the number of measurements. In this study, an experimental study of millimeter-wave imaging at 60 GHz center frequency is presented. The masks used in compressed sensing are designed to have a new mask in each row/column motion to approach real time imaging. The effect of the acquired data type and modulation frequency on the reconstructed image is investigated.
