Abstract :
In this paper, modeling and simulation of chaff cloud using fullwave electromagnetic solver is presented. Scattering characteristics of chaff using a cloud of strip dipoles has been studied in presence or large target. The influence of mutual coupling between the dipoles is taken into account. Randomly oriented and distributed chaff cloud is generated using automated script. Both monostatic and bistatic RCS of chaff cloud in presence of 41 meter large aircraft is calculated using Finite Difference Time domain (FDTD) solver of EMPro simulation tool. It has been shown that complicated chaff cloud can be modeled and analyzed without any approximations or simplifications, in a relatively reasonable time, using the electromagnetic Finite Difference Time Domain (FDTD) solver.
