A Method for Missile Autopilot Performance Evaluation

The essential benefit of HardWare-In-the-Loop (HWIL) simulation can be summarized as that the performance of autopilot system is evaluated realistically without the modeling error by using actual hardware such as seeker systems, autopilot systems and servo equipments. HWIL simulation, however, requires very expensive facilities: in these facilities, the target model generator is the indispensable subsystem. In this paper, one example of HWIL simulation facility with a target model generator for RF seeker systems is introduced at first. But this generator has the functional limitation on the line-of-sight angle as almost other generators, then, a test method to overcome the line-of-sight angle limitation is proposed.
