Visualization of Chaff Cloud Aerodynamics based on Random Generation of Chaff Dipoles in 3D Space

Chaff is one of the most widely used and effective expendable electronic attack (EA) devices. It is a form of volumetric radar clutter consisting of multiple metalized radar reflectors known as chaff fibers designed to confuse hostile radar operation. It is dispensed into the atmosphere to deny radar acquisition, generate false targets. To understand the dynamics of chaff cloud, a software has been developed by introducing a methodology which takes concern of various dynamic parameters like ejection velocity, blooming and settling, and terminal velocity of chaff fiber. The software is developed in a high level programming language, known as MATLAB[1]. The chaff fibers were generated randomly in 3D space at t=T 0, i.e. ejection.Then the blooming code wasimplemented on these randomly distributed fibers to visualize the entire 3D chaff cloud at any given time (t). Output of the software is in the form of images and video which show the complete evolution of chaff cloud and its final settling. In images as output, the chaff fiber distribution in 3D space was shown on different time. In video as output, all the images were taken in sequence in MATLAB and the complete blooming is visualized. This software finds its main application in evaluating the dynamic RCS behaviour of chaff cloud.
