SCNS/FLIR Target Locating
| Abstract: | To improve the operational capability of the Special Operations Forces (SOF) aircraft, the U.S. Air Force plans to integrate the AN/AAQ-17 forward looking infrared (FLIR) system on SOF C-130 aircraft equipped with the Self-Contained Navigation System (SCNS). As part of this integration, the SCNS will provide pointing information to the FLIR so that a navigator can locate fured reference points (RPs) on the ground (e.g., a water tower of known coordinates). This paper presents the analysis for optimizing pointing information for locating RPs and the recommendation for a more successful pointing algorithm. This investigation demonstrated the necessity of evaluating the FLIR maximum likelihood pointing angles. The maximum likelihood angle is that angle that maximizes the probability that the reference point appears in the FLIR field of view (FOV). If the FLIR is pointing at the SCNS-estimated RP location instead of the maximum likelihood angle, there could be a significantly larger probability that the RP is not within the FOV. The technique derived in this analysis for maximum likelihood pointing angles can and should be applied in any integrated navigation and pointing search system. |
