Method for Improving Detection Efficiency of Microwave Staring Correlated Imaging

A method for improving the detection efficiency of Microwave Staring Correlated Imaging (MSCI) is proposed in this paper. Via the judgment from Gram-Schmidt Orthogonalization and the process of expanded selection, a refined collection of feasible independent radiation fields are picked out from huge amount of original radiation fields, ensuring that the imaging matrix keeps a full rank property at the same time. Numerical imaging results based on the selected radiation fields demonstrate that the proposed method effectively improves the detection efficiency of MSCI, which makes MSCI better applied in fast imaging applications.
