Book excerpt: The Eglin FPS-85 space surveillance radar is a bi-static phased array radar system located in Northern Florida. In 1994, when a new radar control computer was installed at Eglin, the software for the debris fence was not budgeted. The radar only maintained the capability to erect low elevation angle surveillance fences. The software was upgraded in 1999 to create the debris fence, which extends from 155 to 205 degrees in azimuth and is scanned at 35-degrees elevation. This higher elevation angle enables the detection of smaller-sized debris objects at manned space flight orbits. In this configuration, the radar system has a 0.99 probability of detection for all objects that have a radar cross-section greater than -35 dBsm. The new debris fence is intended to enhance the AFSPC's and NASA's ability to detect small debris objects, which are not currently part of the SSN satellite catalog. This paper presents data collected during software version 99-1 development testing.
Download or read book Surface and Anomolous Waves on Phased Arrays of TEM Waveguides with Fences written by Robert J. Mailloux and published by . This book was released on 1971 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report describes the behavior of an infinite array of parallel plane waveguides in a conducting ground plane with metallic fences perpendicular to the ground plane and spaced halfway between each pair of radiators. The study is mainly concerned with anomolous wave nulls and their relation to endfire surface-wave radiation, and, in addition, some data is presented to demonstrate the scan-matching properties of the fence geometry. An interesting new development in open periodic structure theory is reported and is shown to apply to both surface waves and anomolous waves. Certain restrictions on the phase distributions of the aperture fields and fence currents are revealed and studied in detail. In addition to these basic relationships, a numerical study of the scanning properties of waveguide-fence arrays is presented which has indicated that structures of this type can reduce impedance variation during scan and can be especially useful when it is desirable to scan very near to, or even slightly beyond, the point at which a grating lobe moves into real space.

Download or read book Evaluation of the Multifunction Phased Array Radar Planning Process written by National Research Council and published by National Academies Press. This book was released on 2008-09-14 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Multifunction Phased Array Radar (MPAR) is one potentially cost-effective solution to meet the surveillance needs and of several agencies currently using decades-old radar networks. These agencies including the National Oceanic and Atmospheric Administration s (NOAA) National Weather Service (NWS), the Federal Aviation Administration (FAA), the Department of Defense (DOD) and the Department of Homeland Security (DHS) have many and varied requirements and possible applications of modern radar technology. This book analyzes what is lacking in the current system, the relevant capabilities of phased array technology, technical challenges, cost issues, and compares possible alternatives. Both specific and overarching recommendations are outlined.

Book excerpt: This report describes the methods used to quantify the geometrical properties of the Naval Space Command Naval Space Surveillance Radar Fence. The Space Surveillance system was designed and began operations soon after the launch of the first earth satellites. Its mission is to track and catalog objects passing through the plane of the radar beams. The fence comprises three transmitting sites and six receiving sites spread from Georgia to California, making it one of the largest multistatic radar systems ever conceived. Because of the steady increase in the number of satellites launches and the associated orbiting debris from expendable launch vehicles, the number of objects in the catalog continues to grow. However, the catalog is not all inclusive and includes only a subset of all orbiting objects. At a time where the number of users of the catalog is increasing and the interest in a more complete and accurate description of the hazard is growing, improvements to the fence are being considered.

Download or read book Routledge Handbook of Commercial Space Law written by Lesley Jane Smith and published by Taylor & Francis. This book was released on 2023-07-31 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Routledge Handbook of Commercial Space Law provides a definitive survey of the transitions and adjustments across the stakeholder community contributing to outer space activities. The interaction between NewSpace, traditional aerospace industrials, and non-traditional space-related technologies is driving market changes which will affect state practice in what has until now been a government dominated market. Greater private commercial participation will lead to new economic approaches to risk-sharing models driven by a space services dominated market. This handbook is a detailed reference source of original articles which analyse and critically evaluate the scope of the current paradigm change, and explain why space contracts and risk apportionment as currently known will change in tune with ongoing market transitions. Reference is made to the scope of best practices across various leading states involved in space activities. With contributions from a selection of highly regarded and leading scholars and practitioners in the Commercial Space Law field, and the inclusion of salient documents, regulatory and contractual documents, the Routledge Handbook of Commercial Space Law is an essential resource for students, scholars, and practitioners who are interested in the field of Commercial Space Law.

Available in PDF, EPUB and Kindle. Book excerpt: Presented is an analytical approach to the study of the system-performance aspects of phased array radars using integro-differential tensor forms. Using tensor transformations between different coordinate systems we examine some of the most important system surveillance parameters for static and rotating phased array radars facilitated by an analysis on space-like and time-like manifolds. The mathematical approach discussed allows the derivation of the optimum configurations between the two types of arrays and a comparison between the two systems is made.
