The use of point-to-point lasers for navy ships

Bonk, Scott S. 06 1900 (has links)
Approved for public release; distribution is unlimited / Currently the Navy uses microwave technology to wirelessly connect ships at sea. These systems provide approximately a 1.5Mb/s transfer rate and have some significant drawbacks. Microwave antennas provide a very large electromagnetic signature, require a large power source, and require a lot of support equipment and personnel to maintain connections. Laser technology can offer connection speeds 50 times greater than microwave, have no electromagnetic signature, use only a fraction of the space and power requirements, and require little to no personnel maintenance. Lasers offer many advantages to its microwave counterpart but it may also have some drawbacks. This paper addresses the effects inclement weather will have on range and bandwidth. Weather ranging from fog to heavy rain also is analyzed in relation to the current system. Aside from communications between ships, lasers offer other untouched tactical benefits including - enhanced communications between ships and remote controlled drones. Unmanned vehicles could provide full motion video, telemetry, atmospheric conditions, and provide an uplink for smaller water or land based terminals to the ship. / Ensign, United States Navy

Microwave Wireless Communication Link Base Band Part

Jamil, Faisal January 2006 (has links)
<p>This thesis was completed as a part of the project "Microwave wireless Communication </p><p>Link". In this thesis, the requirements to develop base band part for the transceiver were </p><p>studied, including, usage of proper hardware equipment as well as software </p><p>programming. A signal injector performed as a hardware interface between the Analog </p><p>part and the Digital (base band) part of the tranceiver, whereas, a PCI card acted as a data </p><p>acquisition device for base band part. A programming language was required to build </p><p>such a software, able to successfully represent a transmitter and a receiver. All the </p><p>features were found in Labview (Laboratory Virtual Instrument Engineering Workbench) </p><p>introduced by National Instruments in 1980s. A modern version of Labview i.e. version </p><p>7.1, was used in this thesis, it views the software as a virtual instrument to automate and </p><p>measure the values passed from the connected hardware. Labview provides a graphical </p><p>development environment, which is modular and parallel in nature, and uses an efficient </p><p>G compiler. A coherent base band receiver using matched filter was implemented, and a </p><p>base band transmitter using NRZ-L digital encoding scheme and QPSK modulation </p><p>scheme was developed.</p>
