Paper Abstract

To be effective a DIRCM must direct a Laser beam exceeding a certain power level towards the approaching missile. This power level inevitably leads to a potential laser hazard mainly regarding the eye safety of people potentially hit by the Laser beam. To evaluate this hazard the IEC 60825-1 is a well established international standard. This leads to the definition of a laser safety zone around the active DIRCM which can be as large as a few hundred meters. Therefore it cannot be excluded, that people are present within this zone. This Laser hazard is also a major topic for a civil or military DIRCM system certification. In this report we analyze the impact of various DIRCM designs on this safety zone as well as the resulting Laser hazard footprint at takeoff and landing. Also some technical means to make a DIRCM system inherently eye safe are discussed. As a result we come the conclusion that an eye safe DIRCM is possible, if appropriate measures are taken throughout the DIRCM system design.
