摘要：
We present a direct imaging algorithm for extended targets using far-field data generated by incident plane waves. The algorithm uses a factorization of the response matrix for far-field data that is derived from physical considerations and a resolution-analysis-based regularization. The algorithm is simple and efficient since no forward solver or iteration is needed. Efficiency and robustness of the algorithm with respect to measurement noise are demonstrated.
