摘要：<p>The system using the characteristic energy radiation in the visible and/or IR range as well as that in the sound wave range, uses a detection sensor(8) an identification sensor (11) and a horizontal sensor (14) controlling the elevation of the previous two. The azimuth and elevation of the identified helicopter are automatically supplied to a control for aligning a weapon with the required firing angle. The identification sensor (11), responsive to modulated rotor radiation in the IR range, is combined with a gas laser (33) directed onto the rotating rotor blades, so that a double shift of the laser signal is caused by the rotor blade movement so that the movement of the helicopter itself is used for identification. The gas laser (33) may form part of a distance measuring device (34, 35). The gas for the laser is pref. carbon dioxide.</p>
