Abstract
An alarm system for military objects of a laser-radiating hostile weapon system. A plurality of units for detecting impinging laser radiation are mounted on an airplane, for example. Each detection unit is arranged to detect in one of six directions along three mutually perpendicular axes. The detection units are coupled to output signals representing the direction of incoming laser radiation to processing electronics. Each detection unit has an array of detector elements in a first plane and a diaphragm equal in size to the array in a second plane parallel to the first plane. The diaphragm and array are arranged so that the direction of the laser radiation can be determined from the pattern of detector elements activated in response to laser radiation passing through the diaphragm.
