A linear sparse matrix configuration capable of multistatic imaging is presented. In order to achieve a wide field of view, a configuration based on a large array of which only a few elements are used for each observation zone is proposed. This upgraded version involves the design of a new imaging strategy, as the image plane is scanned in sections, rather than as in the initial design, where it is fully scanned. With this renewed approach, imaging performance is significantly improved and, since only the elements closest to the scanned area are used (the same number as in the base configuration), data acquisition time is not affected. This array thus designed would move vertically as a synthetic aperture in the vertical plane. Simulation results validating the performance of the proposed architectures are shown. This contribution is intended to help the development of better imaging systems for security applications in the near future.
