Abstract : A test and evaluation was conducted at the Federal Aviation Administration Technical Center to compare the surveillance performance and the range and azimuth accuracy of the Air Traffic Control Radar Beacon System (ATCRBS) mode of the Mode S (formerly the Discrete Address Beacon System (DABS)) to that achieved with the existing Automated Radar Terminal System (ARTS) III. Targets of opportunity and ATCRBS-equipped Technical Center test aircraft were used in this evaluation. The 5-foot ATCRBS antenna at the Technical Center Mode S terminal sensor was used to collect data at both the Mode S and the ARTS III sensors. Data reduction and analysis tools developed by the Technical Center were used to determine sensor performance characteristics and to highlight areas for further analysis. It was concluded that the ATCRBS mode of the Mode S sensor provided improved blip scan ratio, Mode A code, and altitude reliability performance when compared to the ARTS III. The Mode S sensor also provided better range and azimuth accuracy than the ARTS III. (Author)
