DOI: 10.1109/lgrs.2022.3175822
Abstract: When a sparse reconstruction (SR) space-time adaptive processing (STAP) strategy is employed for sea clutter suppression, the computational burden imposed by the spectrum reconstruction process is still a challenge. Hence, a low-complexity multiple-input multiple-output (MIMO)… read more here.

DOI: 10.3390/app13095653
Abstract: In an airborne passive radar, multipath (MP) clutter, which is caused by MP signals contained in the contaminated reference signal, degrades the space-time adaptive processing (STAP) performance. The MP clutter suppression algorithm before STAP can… read more here.
