Abstract

The Navy has a need to score Naval Gunfire Support exercises using a virtual land mass, positioned off the Pacific Missile Range Facility (PMRF) at Barking Sands, Kauai, Hawaii, as a target. The target area is approximately 15,000 yards from shore. As a part of this exercise, illumination rounds that detonate 1000 to 1500 feet above the surface and airburst high explosive rounds that detonate approximately 50 feet above the surface must be scored. The design requirements for the measuring system for the illumination rounds is detonation position accuracy in three dimensions of approximately +/- 15 yards and for the high explosive airburst rounds the determination of air as opposed to water detonation. Detection and measurement is to be automatic. The optical portion of the system consists of two shore based high resolution CCD cameras mounted on precision rotators, surveyed in via GPS and supported by appropriate hardware and software. One station is located 80 feet above sea level and the other is located 1500 feet above sea level. Data from both stations is telemetered to a central station for position computation and display. The base line along the shore is approximately 10,000 yards. Preliminary measurements, system design, error analysis, and calibration techniques will be discussed.
