Abstract

An evaluation tool for the effectiveness of infrared decoys against anti-ship missiles has been built. In a flexible software setup, different methods of preprocessing and detection can be chosen for the processing of recorded infrared image sequences. Since a flying missile seeker with a variable speed and variable starting distance is simulated, the recorded images, from a static camera or a camera moving at relatively low speed, are corrected before they are fed into the seeker algorithm of the simulated missile. MODTRAN and the Naval Aerosol Model are used to calculate the atmospheric transmission effects in the preprocessing. The hot spot seeker algorithm uses features such as contrast and position above or below the horizon to differentiate between ship, infrared decoys and false alarms resulting from clutter. During the simulation the track window of the seeker is visualized on the recorded images. The aim point of the missile during the flight is logged in a file to enable evaluation. With this tool the effectiveness of a recorded decoy deployment in various scenarios can be evaluated by varying the missile parameters such as distance between missile and ship when the first decoy is deployed, missile search algorithm, and missile track algorithm.
