MIMO SAR Imaging for Wide‐Swath Based on Compressed Sensing

Mathematical Problems in Engineering, Volume 2017, Issue 1, 2017., 2017
To reduce the amount of data to be stored and software/hardware complexity and suppress range ambiguity, a novel MIMO SAR imaging based on compressed sensing is proposed under the condition of wide‐swath imaging. Random phase orthogonal waveform (RPOW) is designed for MIMO SAR based on compressed sensing (CS).

Investigation on Beamspace Multiple‐Input Multiple‐Output Synthetic Aperture Radar Data Imaging

International Journal of Antennas and Propagation, Volume 2016, Issue 1, 2016., 2016
The multiple‐input multiple‐output (MIMO) technique can improve the high‐resolution wide‐swath imaging capacity of synthetic aperture radar (SAR) systems. Beamspace MIMO‐SAR utilizes multiple subpulses transmitted with different time delays by different transmit beams to obtain more spatial diversities based on the relationship between the time delay ...

An Efficient Signal Reconstruction Algorithm for Stepped Frequency MIMO‐SAR in the Spotlight and Sliding Spotlight Modes

International Journal of Antennas and Propagation, Volume 2014, Issue 1, 2014., 2014
Multiple‐input multiple‐output (MIMO) synthetic aperture radar (SAR) using stepped frequency (SF) waveforms enables a high two‐dimensional (2D) resolution with wider imaging swath at relatively low cost. However, only the stripmap mode has been discussed for SF MIMO‐SAR.
