研究目的
To develop a computationally efficient imaging algorithm that can obtain high-quality 3-D reconstruction based on planar MIMO array.
研究成果
The proposed omega-K algorithm (ωKA) for 3-D reconstruction based on planar SIMO/MIMO array demonstrates high computational efficiency and imaging accuracy. It opens a potential for real-time operation in near-field 3-D high-resolution imaging applications such as through-wall surveillance, security check, and subsurface detection.
研究不足
The RO correction is achieved by an approximate way, which introduces spatial limitations for accurate reconstruction. The algorithm's performance is constrained by the residual error after CDROC, requiring the imaging area to be partitioned into blocks if too large.
