This report describes the tests being conducted to determine what effect the implementation of the Discrete Address Beacon System (DABS) will have on the performance of the Air Traffic Control Radar Beacon System (ATCRBS), and presents interim results on the tests conducted to date. Uplink tests were conducted to measure transponder suppression rates in the ATCRBS airborne environment under various DABS and ATCRBS ground interrogator site configurations. Analysis of the data collected to date indicates that suppression levels generally become lower when DABS sensors replace ATCRBS sites, thus, resulting in an improvement in the ATCRBS airborne environment. Tests were also conducted on three reply processors being used by the Federal Aviation Administration (FAA) in operational facilities to process ATRCBS targets to determine processor susceptibility to DABS fruit interference. There was no indication from the resultant data of any significant degradation in performance in the presence of varying amounts of DABS fruit.
