Review Of Faa Procurement Of Airport Surface Detection Equipment Asde 3 PDF Download

The Airport Surface Detection Equipment (ASDE)-3 radar test bedat the Federal Aviation Administration (FAA) Technical Center was installed and evaluated in 1980. Resulting from these tests, it was noted that additional information was required prior to the issuance of the procurement specification. Specifically, the three objectives were: (1) an investigation of anomalous elongation of target returns from F-106 aircraft; (2) to determine if there is an improvement in system performance when oversized waveguide is installed in lieu of standard Ku band waveguide; and (3) a comparison of linear vertical, linear horizontal, and right hand circular antenna feed polarizations with respect to clear weather target imaging performance. This report documents the evaluation conducted and the results of this evaluation. The results indicated that: (1) the target elongation is generated by intermediate frequency (IF) amplifier saturation; (2) oversize waveguide improves system performance and should be utilized for long radiofrequency (RF) runs; and (3) linear polarization improves clear weather target imaging and should be provided to the controller as an option.
