| CWO John Walker led one of the most devastating spy rings ever unmasked in the United States. Along with his brother, son, and friend, he compromised U.S. Navy cryptographic systems and classified information from 1967 to 1985. This research focuses on just one of the systems compromised by John Walker himself: the Fleet Broadcasting System (FBS) during the period 1967-1974, which was used to transmit all U.S. Navy operational orders ... |

Ronald O'Rourke; LIBRARY OF CONGRESS WASHINGTON DC CONGRESSIONAL RESEARCH SERVICE
|
 | The concept of network-centric warfare (NCW) is a key element of the Department of Defense's (DoD's) transformation effort. NCW focuses on using computers, high-speed data links, and networking software to link military personnel, platforms, and formations into highly integrated local and wide-area networks. Within these networks, personnel will share large amounts of critical information on a rapid and continuous basis. DoD believes that NCW will dramatically improve combat capability and ... |

Brian Higgins; NAVAL POSTGRADUATE SCHOOL MONTEREY CA
|
| The goal of this thesis is to investigate the effectiveness of a trolley interface for ship-to-ship cargo transfer. The new interface alleviates some of the torsional problems associated with existing ramp designs and can be effectively utilized for both skin-to-skin and Roll-On Roll-Off operations. A mathematical model is developed in order to predict cargo transfer rates in a seaway. Three dimensional hydrodynamic analysis data are used to calculate expected transfer ... |

Alfredo Rodriguez; NAVAL POSTGRADUATE SCHOOL MONTEREY CA
|
| A proposed U.S. Navy ship to ship, line of sight, high data rate communication system is analyzed. Because of the limited bandwidth available in the UHF band, it is desired to reuse a frequency channel at the shortest possible range. By limiting the radiated power to the minimum required to establish a desired quality of service, the channel can be reused at considerably shorter ranges ... |

|
| This document is a continuation and expansion of an earlier study that examines the feasibility of using the evaporation duct to support an alternative high-speed communication system for Navy applications. This Evaporation Duct Communication (EDCOM) experiment is a unique opportunity to evaluate another communication channel that can alleviate Navy ship-to-ship communication problems. Therefore, it is strongly recommended to proceed with this measurement program. (Author) |

| The Evaporation Duct Communication (EDCOM) project is an effort to provide an alternative ship-to-ship communications channel using the natural environment. A microwave communication link can be used on an over-the-water, over-the-horizon path through the evaporation duct. This report shows how a microwave communication link, operating at a range separation of more than twice the line-of-sight range, can be constructed. This link can achieve about 80- percent availability at a transmission ... |

| A multiple frequency quaternary phased shift (MFQPSK) signaling system has been developed and experimentally tested in a controlled environment. In order to insure that the quality of the received signal is such that information recovery is possible, error detection/correction (EDC) must be used. This thesis reviews various EDC coding schemes available and analyzes their application to the MFQPSK signal system. Hamming, Golay, Bose-Chaudhuri- Hocquenghem (BCH), Reed-Solomon (R-S) block codes as ... |

| This report briefly describes the development of a low-cost, ship-to ship optical communications system (OCS) under a six-month Phase I Small Business Innovative Research (SBIR) contract. Laser communication systems have been developed for use at fixed ground stations, aircraft, and satellites. However, they have not been successfully used in ship-to-ship applications. The difficulty is that ships have large, random linear random linear and angular motion, which interferes with holding a ... |

| An analysis of two sets of atmospheric optical and supporting meteorological data has been performed. The first data set was taken by an airborne differential absorption lidar (DIAL) system. From this data set, vertical water vapor density profiles were extracted and used to calculate transmittances for cw and pulsed DF lasers. Thermal blooming calculations also were made to compare the performance of a laser optimized using a standard atmosphere water ... |

| To do absolute optical transmittance measurements between two ships requires that the light source and the receiver reciprocally track each other. This report describers the tracker equipment designed to do this measurement and the tracking ability test results of January 1982. We demonstrated a dynamic tracking error of 20 microrad in both azimuth and elevation. The modified Nike- Hercules tracker has a 32 in. primary. The receiver includes a modified ... |

| As investigation was made of the practicality of assessing anti- submarine warfare (ASW) team performance by means of measures of the volume of communications. A system for classifying communications was developed based on an analysis of published data on communication rates (e.g., number of evaluative messages sent per minute) of ASW helicopter crews. Next, communication rates were recorded for ship's teams during two exercises in the 14A2 ASW team trainer. ... |

| The document addresses ship-to-ship tactical hf communications (groundwave distances over seawater). It provides performance predictions in ready-to-use graphical form, and discusses transmission system factors that influence system performance. It suggests a deviation from the traditional procedure of tactical hf frequency assignment (static assignment in the 2-6-MHz band) to a more dynamic assignment procedure by making assignments based upon the tactical situation and performance predictions covering the entire hf band.
