Download or read book Air Defense Initiative ADI Clutter Model written by and published by . This book was released on 1998 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a republication of RADC-TR-90-170. This technical report documents a detailed radar clutter model utilized throughout the duration of the Air Defense Initiative (ADI) program conducted by the US Air Force from 1985 to 1995. One objective of this effort was to identify possible sources of false alarms in an airborne early warning (AEW) radar environment, and quantify the number of sources as a function of radar frequency, location, season, and time of day. Analysis is presented for radars designed to operate at UHF, L-Band, and S-Band. The environments modeled included tropospheric clutter (precipitation, lightning, and turbulent layer), sea clutter (open sea and land-sea interface), distributed terrain clutter, discrete manmade clutter (buildings, vehicles, and vessels), angels (birds and insects), and aurora. ADI was initially created to provide for a defense against low radar cross section threats. The most significant problem facing ADI is achieving a high probability of detection against modern targets while maintaining very low false alarm rates due to clutter returns. Given the power and size constraints of an AEW radar, most of the burden for achieving this performance is placed on waveform design and signal processing which, in turn, is strongly influenced by how the interference from the clutter environment is defined.

Book excerpt: Strategic Defense Initiative examines developments in the technologies currently being researched under SDI. The OTA does not repeat the work of its earlier reports but gives special attention to filling in gaps in those reports and to describing technical progress made in the intervening period. The report also presents information on the prospects for functional survival against preemptive attack of alternative ballistic missile defense system architectures now being considered under the SDI. Finally, it analyzes the feasibility of developing reliable software to perform the battle management tasks required by such system architectures.

Download or read book A 10s Over Kosovo written by Phil M. Haun and published by www.Militarybookshop.CompanyUK. This book was released on 2011 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: First published in 2003. The NATO-led Operation Allied Force was fought in 1999 to stop Serb atrocities against ethnic Albanians in Kosovo. This war, as noted by the distinguished military historian John Keegan, "marked a real turning point . . . and proved that a war can be won by airpower alone." Colonels Haave and Haun have organized firsthand accounts of some of the people who provided that airpower-the members of the 40th Expeditionary Operations Group. Their descriptions-a new wingman's first combat sortie, a support officer's view of a fighter squadron relocation during combat, and a Sandy's leadership in finding and rescuing a downed F-117 pilot-provide the reader with a legitimate insight into an air war at the tactical level and the airpower that helped convince the Serbian president, Slobodan Milosevic, to capitulate.
