Multiple Sensor Simulation in Support of Helicopter Day, Night and All Weather (DNAW) Operation

This paper presents an implementation of an IIMMW simulator for use in developing a multisensory fusion methodology for Helicopter DNAW operations. The functional modeling approach based on power representation of the simulated sensors is adopted in the simulation. The detailed power and attenuation models are described and the received power from the target and background is converted into intensity values and rendered as an image. The effect of various weather conditions including rain, fog, snow and dust are considered. As a result, some examples of simulated MMW and IR images generated by the simulator are shown.
