1. Coast Guard Research & Development Center Multi-Sensor Performance Prediction (MSPP) Tool-Set Kim Babcock U.S. Coast Guard R&D Center

2. What is MSPP? Coast Guard analyst software tool to estimate sensor performance • Validated • User-Friendly • Well-Documented Fills the shortfall for data that cannot be obtained from field tests

3. Sweep Widths • Lateral Range Curves • Instantaneous Probability of Detection Plots - Radial - Azimuthal • Target • Environment - Weather - Location - Date/Time • Platform • Sensor • Mode RADAR SENSORS AREPS Detection (Advanced Refractive Effects Prediction System - SPAWAR) NIGHT VISION & INFRARED SENSORS TAWS (Target Acquisition Weapons Software - AFRL) Detection Classification Evaluation What is MSPP? (Cont’d) Inputs Engine: DoD Models Outputs THE BETTER THE INPUT, THE BETTER THE OUTPUT!

4. MSPP User Input Options PLATFORMS Air– CG helicopters & fixed wing aircraft Surface – CG patrol boats, medium & high endurance cutters SENSORS (multiple modes per sensor are available) RADAR – SPS/73, APS-127, APS-137, APS-143, SINS 1933C INFRARED – Wescam DSi, Milcam XP+, CASPER-IR, MARFLIR-IR NIGHT VISION – PVS-5, 7, 7C, 14 PRE-DEFINED ENVIRONMENTS CG District 1 (good, average, poor) CG District 7 (good, average, poor) Cape Cod (7am or 7pm local in Feb, May, Aug, Nov) Key West (7am or 7pm local in Feb, May, Aug, Nov) ** users can create and/or edit platforms, sensors & environments **

9. Platform: Air (altitude: 500ft) Sensor: OldIR and NewIR Target: 6-Person Raft with 2 People Environment: Cape Cod August, 11pm local time MSPP Sample Output Radial Plots of Instantaneous Probability of Detection These results indicate that in both NFOV and WFOV, OldIR provides moderately better detection results than NewIR.

10. MSPP Sample Output Platform: Air (altitude: 500ft) Sensor: OldIR and NewIR Target: 6-Person Raft with 2 People Environment: Cape Cod August, 11pm local time Azimuthal Plots of Instantaneous Probability of Detection (POD) NewIR OldIR Wide FOV Wide FOV These azimuthal plots use color to POD at increasing ranges from the center where the sensor is positioned. As in the previous slide, these results indicate that in both NFOV and WFOV, OldIR provides moderately better detection results than NewIR. 100 50 Narrow FOV Narrow FOV 0 POD Key

11. FY05 MSPP Tasks • Modify MSPP for unrestricted operation • implement the same approach used by TAWS • Incorporate radar wind-dependent sea clutter model (AREPS) • Investigate requirements to interface/integrate MSPP with mapping software such as ESRI’s Arc View • Add graphical output to batch mode (currently tabular)

12. MSPP Wish List • Validation of method used to estimate minimum detectable temperature (MDT) data for IR predictions • Expansion of MSPP Prediction Capabilities • Addition of CCD TV model (planned FY06) • Visibility impact on IR/NVG predictions (planned FY06) • Account for target height in IR/NVG max range predictions • Modeling of retro reflective effects for NVG • Modeling of unaided visual detection • Effects of radar scan-to-scan integration
