EXTENSION OF SHIPBOARD EXTERIOR COMMUNICATIOIN DESIGN ANALYSIS TO WIDEBAND SYSTEMS

摘要

This paper describes the extension of present shipboard exterior communication design analysis to wideband systems.The present design procedure is an iterative process by which candidate RF-system designs can be analyzed to determine their relative desirability.To support the design procedure,a pair of system-modeling computer codes:Design (Communications) Algorithm (DECAL) and Performance Evaluation (Communications) Algorithm (PECAL) were developed.Both DECAL and PECAL analysis have been limited to narrowband communications.Recently,a new system analysis model called COSAM Ⅱ (DECAL/PECAL) has been developed which can perform a topside Electromagnetic Compatibility (EMC) analysis involving both narrowband communications and wideband communications not previously used by the US Navy.
