An Innovative Fuzzy-Logic-Based Strategy for an Effective Exploitation of Noisy Inverse Scattering Data

Abstract

Abstract-This paper presents an innovative inverse scattering approach based on a fuzzy-logic strategy aimed at fully exploiting the information content of the scattered data in a microwave imaging system. The effectiveness of the proposed method is assessed through the results of a numerical analysis concerned with the reconstruction of single as well as multiple dielectric targets in various noisy environments. For comparison purposes, the obtained performance are compared with those of a standard method in terms of reconstruction accuracy and computational load to point out the improvement induced by the proposed approach.

Angular-Diversity Radar Recognition of Ships by Transformation Based Approaches --- Including Noise Effects

“…However, this is not important because our main purpose is to illustrate that the transformation based approaches can reduce the dimensions of scattering data, tolerate noise effects and achieve high recognition rate in such angular-diversity arrangements. From physical points of view, the radar recognition from RCS is basically an approximate approach of inverse scattering [9][10][11][12][13][14]. Similar to the angular-diversity reconstruction of target shape in inverse scattering, the target ships are well classified by their angular-diversity RCS characteristics in this study.…”

Exploitation of Te-Tm Scattering Data for Microwave Imaging Through the Multi-Scaling Reconstruction Strategy

“…Dealing with two-dimensional inverse scattering problems, the transverse electric (T E) illumination and the transverse magnetic (T M ) illumination are usually taken into account. The latter has been more frequently used [16][17][18] because of the scalar nature of the arising scattering equations. Notwithstanding, the use of T E-polarized incident waves implying the solution of vectorial integral equations have been considered [2,[19][20][21][22][23][24][25][26][27], as well.…”
