MATLAB-Based 3-D MoM and FDTD codes for the RCS analysis of realistic objects

Abstract

Three-dimensional (3-D) MAT-LAB-based codes are developed for radar cross-section (RCS) modeling and simulation (MODSIM) using method of moments (MoM) and finite-difference time-domain (FDTD) approaches. Any object can realistically and comparatively be investigated. Electrical engineering education and training necessities electromagnetic (EM) MODSIM approaches [1]–[2][3]. Modeling and simulation has long been discussed in this magazine both as feature articles and as tutorials in this column. Multipurpose two-dimensional (2-D) FDTD-based education/training tools have been developed and shared with the reader [4], [5]. A series of articles [6]–[7][8] discussed RCS modeling and simulation and presented 3-D FDTD-based RCS packages. Finally, MATLAB-based 2-D FDTD codes were introduced to the use of the reader who is interested in EM MODSIM.
