IMPROVED TRACE (TAXIING AND ROUTING OF AIRCRAFT COORDINATION EQUIPMENT) DETECTORS.
Abstract
Results are reported of technical and operational tests of a system designed to detect aircraft movements on the airport surface and in the approach zone of a runway. This system, known as TRACE (Taxiing and Routing of Aircraft Coordination Equipment), consisted of three equipments employing different techniques for aircraft detection. The techniques employed were: (1) a modified induction loop detector, (2) a modified cw doppler detector (S-band), and (3) an fm/cw doppler detector (X-band). Operational tests were conducted on each of the three types of detector units to determine their capabilities of detecion and coverage patterns. Aircraft were taxied at various speeds through the detection fields as well as flown at various altitudes in the approach zone of the runway to determine the respective coverage patterns. In addition to gathering information on the reliability of each type of unit, tests were made to determine the effects of climatic variations and lightning discharges, and the susceptibility of units to false triggering due o rain, foliage, and/or bird movements. Test results indicate that the fm/cw doppler detection technique requires major modification to become suitable for use in a detection system. (Author)
