本文提出了一种用于汽车(低太赫兹)雷达的前向扫描合成孔径雷达方法，该方法将场景扫描和合成孔径处理相结合，从而提高了角度分辨率，改善了成像效果。我们提出了两种算法，一种是改进的反向投影(BP)算法，另一种是基于压缩感知的BP算法。我们提出了降低所提出算法的计算复杂性的技术。仿真和真实数据实验结果验证了本文提出的方法和算法的有效性。
In this paper, we propose a forward scanning synthetic aperture radar methodology for a forward-looking automotive (low-terahertz) radar, which combines scene scanning with synthetic aperture processing, resulting in enhanced angular resolution and improved imaging. We propose two algorithms, first, a modified back-projection (BP) algorithm and, second, a compressed sensing-based BP algorithm. We suggest techniques to reduce computational complexity of the proposed algorithms. Results of simulation and real-data experiments corroborate the validity of our proposed methodology and algorithms.
