Abstract
In view of the problem of simplicity in test project of infrared search and track system(IRST) in current, a test equipment taking into account both operating range and tracking accuracy was designed by combining the theory of operating range test and dynamic target. Temperature-control blackbody and step attenuator module were used to simulate remote target, and arm structure with double mirror has been used to simulate target movement, these could promote simulation effect of dynamic target. The control system of test equipment was designed. On the basis of analyzing test accuracy of each part of equipment, the errors were caused by rotating of arm structure were analyzed emphatically by software of finite element analysis. In the rotating speed of 6 rad/s, the error of tracking accuracy is 0.76, and equipment could meet requirements of test accuracy. The design provides feasible method and theoretical basis on developing and improving of test equipment of IRST.
