Availability Estimate of a Conceptual ESM System.
Abstract
As part of an overall Electronic Support Measures (ESM) improvement program, a study was performed to define a high-availability conceptual ESM system. Prior studies of existing shipboard ESM systems have (1) outlined component units needing improvement and (2) established the characteristic availabilities of two existing systems as well as goals (or standards) for ESM availability. This report defines the operating, support, and maintenance requirements of a proposed ESM (conceptual design) system with a potential for performance modernization and availability improvement over existing shipboard systems. Modernization as used here refers to configuration redundancy for broad frequency coverage and independent performance modes (for easy growth to meet new threats) and configuration flexibility to permit incorporation of advanced technology. The first task was to determine the performance requirements of the conceptual ESM by means of a functional block diagram. Existing off-the-shelf components were identified to represent nearly all of the exterior mast-mounted equipment and some of the interior below-deck equipment. The remaining portion of the equipment was modeled by selecting representative quantities and types of active devices. Failure rates and cost figures were compiled for all components. Next, modes of operation and operating requirements were established along with the attendant automatic and operator-controlled functions and types of operator interfaces. System redundancy was defined for each mode of operation.
