摘要: 为了在实际条件下验证稀疏阵列孔径综合方法可以避免稀疏阵旁瓣较高的问题，以及基于压缩感知理论的成像算法可以对具有稀疏特性的目标进行重建，开展了微波暗室实验。针对实验中的阵列误差，给出了具体的校正方法。通过实验数据处理证明了阵列误差校正方法、稀疏阵列孔径综合方法以及基于压缩感知理论成像算法的正确性和有效性。Abstract: The anechoic chamber experiment is carried out to prove that in practical condition the thinned array aperture synthesis method can avoid the thinned array high sidelob, and the imaging algorithm based on compressed sensing theory can reconstruct the sparse target. For the array errors in experiment, the corresponding calibration methods are presented. Via experiment data processing, the validity of array error calibration method, the thinned array aperture synthesis method and the imaging algorithm based on compressed sensing theory are testified.
