Integration of a Maritime Modeling Capability into the Infrared Sensor Stimulator (IRSS)

The Office of the Secretary of Defense (OSD), Central Test and Evaluation Investment Program (CTEIP) is tasked with providing a coordinated process for making joint investments in defense test and evaluation (T&E) to offset the challenges presented by declining investments in test assets and increasing test requirements. Under CTEIP sponsorship, the Navy and Air Force are jointly developing three Joint Installed System Test Facility (JISTF) enhancements that are based on dynamic virtual reality simulation technology. The three enhancements are the Infrared Sensor Stimulator (IRSS), Generic Radar Target Generator (GRTG), and Joint Communications Simulator (JCS) . These enhancements will provide each ISTF with the capability to simultaneously test multiple avionics and sensor subsystems installed on an aerospace System Under Test (SUT) (e.g., manned and unmanned aircraft) in a ground test environment. The ISTF enhanced test capabilities will be used to evaluate multisensor data fusion/correlation and subsystems interoperability for Infrared Sensors, RADAR, GPS, and Communications and Data Link subsystem. The IRSS program was previously briefed at the 1997 and 19982 GTM&V Conference. This paper addresses the integration of a maritime modeling capability into the IRSS Scene Generation Subsystem (SGS). This paper will outline the basic process of the integration of the extracted and reworked portions of IRENE into IRSS and several of the challenges, issues, and solutions that accompanied this task.
