Abstract:Flight simulation at the different stages of the seeker development plays an important role. Based on microwave dark room environment composite seeker flight simulation test automation system for the engineering background, containing a main control system, a three-axis turntable, 2 D target three subsystem, is a collection of machine, light and electricity as one of the large-scale comprehensive test system. This paper details with the hardware and software design principle of the testing system, through the five axis system design, separation of the turntable and the target in lockstep, the accuracy of 2 D target simulator smooth transmission, gyro orientation test turntable angle correction algorithm several big key innovative technology, established a set of flight simulation test automation system, solved the target trajectory simulation and seeker debugging test problem, has realized the dynamic characteristics of a microwave/ir compound seeker of test automation.
