Weapon System Performance Analysis for an I2R Seeker Integrated with INS/GPS

Donald A. Kelly and M. Scott Heiman

Abstract:	The Air Force’s is investigating the feasibility of placing terminal seeker systems on guided air-to-surface precision strike munitions. One seeker system being considered is Imaging Infrared (I’R). 12R seekers take periodic infrared images of the target area, and then locate the target by comparing this infrared image to an on-board stored image. Sverdrup has developed a medium fidelity model of an 12R seeker using infrared images from flight data. This seeker model is then integrated with an inertial navigation system (INS) that also incorporates global positioning system (GPS) measurements. To determine the accuracy of this INS/GPS/I’R system, the models were placed in the Multimode Simulation for Optimal Filter Evaluation (MSOFE) program developed by the Avionics Laboratory at Wright-Patterson Air Force Base. Combining the seeker model with the MSOFE analysis software has produced an extremely useful analysis tool at reasonable cost. Since MSOFE can operate in Monte Carlo or covariance analysis modes, detailed studies of system performance for various system configurations may be conducted. The purpose of this paper is to briefly discuss some of the capabilities of MSOFE, describe the 12R model, and provide results of the weapon system performance with an 12R seeker.
