提出了一种基于动态合成孔径（DSA）提取特征的交替方向乘子法（ADMM），用于合成孔径雷达（SAR）图像真假目标的重建。这使我们能够并行地解决重建问题，这大大提高了DSA算法的效率，特别是当使用多个DSA时。为了解决ADMM方法中的参数选择问题，已经解决了诸如相干处理增益、目标动态范围、DSA数目和初始收缩等因素，最终导致可靠的重建结果。通过对比实验和对真实的目标的仿真，验证了该算法的准确性。
This paper formulates an alternating direction method of multipliers (ADMM) approach to reconstruct true and false targets in a deceptively jammed synthetic aperture radar imagery based on characteristics extracted by dynamic synthetic apertures (DSAs). This enables us to solve the reconstruction problem in parallel, which considerably improves the efficiency of the DSA algorithm especially when multiple DSAs are used. To tackle the parameter selection problem in the ADMM approach, the factors, such as coherent processing gains, target dynamic range, number of DSAs, and initial shrinkage, have been addressed, eventually leading to reliable reconstruction results. Comparison experiments and simulation of a real target are presented to verify the fidelity of the proposed algorithm.
