Abstract

Acquiring acceptable image quality in Microwave Imaging is one of the challenging tasks in this field. This paper aims to investigate and compare the modified level set method (MLSM) with four s tate-of-the-art methods i. e., distorted born iterative method (DBIM), contrast source inversion (CSI) method, linear sampling method (LSM) and multiple signal classification (MUSIC) method in image reconstruction with focus on quantitative comparison. Furthermore, three important criteria of image quality, namely accuracy, resolution and contrast, are quantitatively investigated for the aforementioned methods. The three quantitative methods of DBIM, CSI, and MLSM start with an initial guess of the scatterer profile and change it in an iterative process to get close to the actual scatterer. Despite large numerical computations, the resolution and contrast in these methods are remarkably high compared to the other two methods. As will be seen, the DBI and CSI methods are capable of completely resolving two objects at 0. 4λ and MLSM at 0. 07λ . Also, the MLSM provides more accurate reconstructions than the other two, since the investigation domain is deformed to a smaller one
