This book was released on 1976 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this research project was to develop a radar technique to detect the presence of flying birds potentially hazardous to aircraft near airport runways; to distinguish them from other radar targets; to estimate the size and number of birds in order to assess the hazard. The motions of a bird in flight are characterized by a distinctive velocity spectrum that can be detected by radar. These 'aural signatures' were identified by Doppler technique and verified by visual sightings. This report provides a description of the analysis techniques, compares range-gated to nonrange-gated systems and also conventional and Doppler radars. A discussion concerning modification of a typical system to a Doppler system is included. A method of determining the actual number of birds in the target volume is discussed. The report also includes a scene-by-scene description of a film presentation made to more fully quantify the Doppler technique. (Author).

Book Synopsis Airport Surveillance Radar Techniques for Applications in Avoidance of Bird/Aircraft Collisions and Improvement of Flight Safety by : Sidney A Gauthreaux (Jr)
Download or read book Airport Surveillance Radar Techniques for Applications in Avoidance of Bird/Aircraft Collisions and Improvement of Flight Safety written by Sidney A Gauthreaux (Jr) and published by . This book was released on 1973 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extensive work with the ASR-4 radar provided basic data that has been analyzed to produce a method that flight controllers can use to collect data on the quantity, size and altitude of birds migrating aloft. A synthesis of radar data collected to date demonstrated the importance of prevailing wind patterns in the evolution of bird migration patterns throughout the continental United States and the world. Analysis of all the direct visual data and radar data gathered with the WSR-57 radar resulted in an updated method of counting the number of migrating birds aloft in much the same manner as weather radar operators measure the intensity of rain storms. A preliminary draft of a manual on radar ornithology to be used by radar operators in the military, the Federal Aviation Agency, and the National Weather Service to detect, identify, and monitor bird movements which might prove hazardous to aircraft has been completed.

Book Synopsis Flight Safety Aspects of Precision Radar Near Air Bases in Bird-Aircraft Collision Avoidance by :
Download or read book Flight Safety Aspects of Precision Radar Near Air Bases in Bird-Aircraft Collision Avoidance written by and published by . This book was released on 1972 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: The utility of a GEC-AEI No. 654 radar for warning of bird hazards at airfields has been evaluated at Gunbarrel Hill and Valmont Reservoir, near Boulder, Colorado, from 16 March to 19 December 1971. Morning and evening flights of Mallards, Canada Geese, etc., provide good test radar targets at these locations. The 654 radar is useful as it is, but improvements are recommended to allow detection of birds at greater ranges. Some doppler radar signature data were also taken with a cw radar at Baller Lake in spring 1971. Experience with this radar provides a basis for recommending further development of signature capability. Such capability should allow determining quickly if a target is caused by birds or not, the type or size of bird, and whether the echo is from one or a small or large number of birds.

Download or read book Development of a 94 GHZ Radar System for Dedicated Bird Detection at Airports and Airfields written by and published by . This book was released on 2006 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: WaveBand as part of a Dual Use and Science and Technology Contract in partnership with the Federal Aviation Administration and the US Air Force Research Laboratory at Rome NY developed a 94 GHz radar named BIRDARTM to detect and report bird activity at airports and airfields and thus prevent potential bird strikes with aircraft during landing and takeoff. The radar is compact utilizing a state-of-the-art 575 mW solid state millimeter-wave power source. WaveBand's patented scanning antenna is used to transmit and receive signals that detect and track birds. The return signals are processed in a radar signal processor incorporated into a low-cost PC architecture. The integrated monitor displays the backscattered power in several ways. The primary format is backscattered power in range versus azimuth angle or transformed azimuth distance. Alternate displays of moving targets superimposed on GIS maps or two-dimensional perspective imagery with near-photographic quality corresponding to the backscattered power are also available. Months of testing at several venues proved the final radar design to exhibit reliable performance. Calibration test and evaluation sites included USAFRL Rome NY; JFK Airport NY; Klamath Basin OR; El Mirage Dry Lake CA; Salton Sea CA; Bolsa Chica Bird Reserve CA; and DFW Airport TX. Small bird detections were reported at distances of 1.2 to 1.3 km and large birds such as geese at distances of 2.3 to 2.6 km during these tests. Final testing at DFW Airport was a great success in that the radar functioned perfectly throughout and was able to detect birds of opportunity at ranges that provided data to substantiate the extrapolation of future radar designs to the detection of large bird flocks at 3 miles. Substantial coverage of the final DFW tests was provided by members of radio TV and the printed press.

Download or read book Joint Agency Doppler Technology Tests written by Ralph J. Donaldson and published by . This book was released on 1980 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Joint Doppler Operational Project was a cooperative inter-agency program directed toward the evaluation of recent advances in Doppler weather radar technology for operational applications by the participating agencies. The first two years of testing demonstrated the decisive superiority of Doppler techniques, in comparison with conventional methods, for reliable identification and early warning of tornadoes and other severe thunderstorm hazards. During the final year, the program evaluated the format and effectiveness of manually aided automatic display products transmitted in near-real time to operational agencies remotely located from the radar. Experiences of operating personnel utilizing these new techniques provide input toward system definition of NEXRAD, the Next Generation Weather Radar network now under development. One of the most encouraging examples of the enhanced warning capability realized by the remote transmission of the automated Doppler format was a successful forecast of severe weather for an Air Force Base which was a crucial factor in saving a fleet of aircraft from severe hail damage.

Book Synopsis Flight Safety Aspects of Radar Techniques in Bird/Aircraft Collision Avoidance by : Warren L. Flock
Download or read book Flight Safety Aspects of Radar Techniques in Bird/Aircraft Collision Avoidance written by Warren L. Flock and published by . This book was released on 1971 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Federal Aviation Administration and Air Force surveillance radars are capable of monitoring bird movements efficiently and can be used to minimize the hazard of collisions between birds and aircraft if those responsible for the operation of these systems take a sufficient interest in this application. This statement is supported by successive-time-exposure photographic recordings of bird echoes seen by the North Platte and Denver radars. In addition, visits have been made to numerous FAA air route surveillance centers in the lower forty-eight states and DEW and AC and W radar sites in Alaska. Simultaneous monitoring of radar screens at three FAA centers on one occasion provided information about bird movements in the area from Ohio on the east to Arizona on the West. Air Force radars in Alaska have provided interesting new information on bird migration between Alaska and Siberia and along the coastline of Alaska. Such use of existing radar systems on a partially multipurpose basis justifies further their expense of operation. The research conducted with the support of the AFOSR has led to new programs of research, at the University of Colorado, involving the bird hazard in the immediate vicinity of airports and the identification of birds by radar.
