A Mathematical Model for Simulating Infrared Images of Ships
Abstract
This element-contribution model is programmed so that the distribution of infrared radiation from a ship target can be calculated for any aspect and any infrared waveband. The present application is to simulate the images formed by the guidance system of an imaging infrared antiship missile. The input data needed are the surface temperatures and emissivities and shapes of the main structures and the equivalent black body temperatures of the sky and sea surface. The shape of each ship is represented as a number of 'boxes' with each side and the top of each box represented by faces of elementary cubes. The positions and the centres of each face are calculated from the positions of three rows of elementary faces measured from plans for each box. The output is an array of numbers representing the radiant intensity from the unscreened faces in the required direction and for the defined waveband. This array can be converted to a colour-coded image on a video display for testing and presentation purposes.
