This chapter focuses on imaging techniques using polyline-shaped MIMO arrays, which serve as an approximate implementation of circular-arc arrays. In Sect. 4.2, we propose an imaging algorithm implemented in a hybrid domain that combines time and spatial frequency processing. Section 4.3 presents an equivalent wavenumber domain imaging technique, associated with phase calibration. Conclusions follow at the end.

摘要

This chapter focuses on imaging techniques using polyline-shaped MIMO arrays, which serve as an approximate implementation of circular-arc arrays. In Sect. 4.2, we propose an imaging algorithm implemented in a hybrid domain that combines time and spatial frequency processing. Section 4.3 presents an equivalent wavenumber domain imaging technique, associated with phase calibration. Conclusions follow at the end.
