Radar Cross Section

Abstract

RCS is a amount of how measurable an object is with radar wave. We have first study to find the rcs of some simple electrodynamics problems with converting their particular fundamental equations into a linear system and on next we have properly describe the Method of Moment for electrostatic problem in which analytical solution of object is hard to compute so we used a numerical technique called Method of Moment. The simulation results of these electrostatic and electrodynamics problems have done on MATLAB, after that when the electrodynamics problem gets complicated for complex object like boat. We approached the comsol software on which the project is based on any object hit by a radar wave; our model of boat reveals the use of a backdrop field in an electromagnetic mirrored problem. Specially build up the backdrop field and sweeping it over a different angles of incidence, this model determine how to calculate the far-field and the radar cross section. Though the modelling process is similar in 3D, this is in 2D to fast set up and solve. The geometry is intentionally kept very simple to focus on the concept. Simulation results have done on COMSOL software.
