Hardware-in-the-loop missile simulation facility

A Hardware-in-the-loop (HWIL) simulation facility has been successfully contributing to the development and evaluation of missiles at the 3rd Research Center, Technical Research & Development Institute, Japan Defense Agency. This facility has two main characteristics. First, it has ability to generate both various RF target and background echoes in several frequency bands. Second, it can be used for the HWIL simulation tests of missiles which have RF/IR dual mode seekers. After the outline of this facility is presented, a technique to overcome the line-of-sight (LOS) angle limitation is proposed, because LOS angle Limitation is inevitable in these HWIL simulation facilities. Moreover, a simulation method for the dual mode seeker missile is shown by using this proposed simulation technique.
