Design of an infrared target simulator for military testing

Aimed at the requirement of terminal guidance simulation test for a certain infrared seeker, an infrared target simulator which is used to complete the non-uniformity correctionand target tracking performance detection was developed. The simulator integrates black body and infrared target simulation system, and switches two working modes (testing and non-uniformity correction) by means of electronic control. This article introduces the main composition, working principle and realization of each subsystem, and tests the key performance indicators of the system. The results show that the parameters of the system meet the design requirements and achieve the desired application results.
