Abstract : This report describes the test procedures and results of the Discrete Address Beacon System (DABS) and Air Traffic Control Radar Beacon System (ATCRBS) compatibility studies performed at the Federal Aviation Administration (FAA) Technical Center. Four terminal ATCRBS processors: Automated Radar Terminal System (ARTS III), ARTS IIIA Sensor Receiver and Processor (SRAP), ARTS II, an AN/TPX-42, and the en route common digitizer were subjected to various anticipated DABS/ATCRBS asynchronous reply (fruit) environments. Maximum expected DABS fruit rates will not degrade performance of facilities using defruited video. The common digitizer, which does not employ a defruiter, performed with no significant degradation in the various DABS fruit environments. The SRAP, which is planned to be implemented interminal facilities to replace the existing ARTS III Beacon Data Acquisition Subsystem (BDAS), will experience overloading of reply and report buffers by the addition of DABS fruit if a defruiter is not used. A defruiter eliminates the overload conditions to the expected maximum DABS fruit rate but adversely affects the SRAP performance.
