Time correlateddata from these OAR flights will then be brought into theHITL facility in an Interface Control Document (ICD)format. The data is fed into the HITL to enablerepresentation of the functions of the radar illuminator,clutter, electronic warfare system modes and timing,target aircraft time-space-position information (TSPI)during OAR flight. This information, alongwith target radar cross section, antenna pattern information,jammer waveforms and timing, as well as other relevant dataare convolved to create time correlated RF energy which isprovided to the HITL simulator via RF waveguide. The HITLseeker simulator is allowed to provide real-time signals tothe guidance computer which gives commands to avalidated real-time flyout of the missile. The output of theHITL testing is vector miss-distance.
