This report is Interim Report Volume 10 for the Cost and Operational Effectiveness Analysis for Ice Patrol Mission Analysis Study. Previous studies have provided a basis for estimating the probability of detection of icebergs by the ANAPS-135 SLAB radar. There is less of a basis for similar probabilities for the ANAPS-137 FLAB. There have been no studies or models which represent the joint effect of the radars. It is necessary to obtain a better estimate of performance from the FLAB radar. Models need to be developed to evaluate the searchimage mode and determine the impact on POD due to intermittent looking. With that knowledge, integration with the existing or upgraded SLAB is possible with the expectation that the joint system POD curves can be developed and, ultimately, search levels may be reduced. The acquisition of the SLAB upgrade in the FY96 ACl BCP is critical in order to maintain the existing high level of program performance. With an expected life of 14 years, the payback period is less than 4.5 years. The SLAB upgrade acquisition must also include a validation and verification component to develop new estimates of probability of detection for the new radar. A number of enhancements requiring follow on modeling efforts are possible. These include expanded track spacing based on revised PODs, digital image enhancement, and full use of GPS with the Tactical Workstation to eliminated position ambiguity and enhance identification of detected targets.
