AIR TRAFFIC CONTROL RADAR BEACON SYSTEM 3-PULSE SIDE LOBE SUPPRESSION EXPERIMENTATION.
Abstract
The report contains the results of technical and operational tests of Air Traffic Control Radar Beacon System 3-Pulse Side Lobe Suppression Development equipment to determine their suitability for implementation of the 3-Pulse Side Lobe Suppression technique. The Side Lobe Suppression Omni-directional Antenna met the side lobe coverage and netting with the Directional Antenna requirements. The colocation siting problems of the Omnidirectional and the Directional Antennas were also investigated and found to be minor in nature. A number of difficulties requiring modification of the ATCBI-2 Transmitter System were uncovered during the experimental testing of the 3-Pulse Modification Kit, but the 3-Pulse Modification Kit did effectively perform the basic requirement of generating the correct number of mode and side lobe suppression pulses. The original Side Lobe Suppression Crystal Diode Switch failed to meet the insertion loss specification, but with the modification of the switch crystals, all specifications were met. The various modifications to incorporate the 3-Pulse Side Lobe Suppression technique were feasible and compatible; and, it was recommended that the modifications be implemented in the Air Traffic Control Radar Beacon System.
