Discrete Address Beacon System (DABS) Air Traffic Control Radar Beacon System (ATCRBS) Interference Analysis.

摘要

The FAA is currently developing the Discrete Address Beacon System (DABS) as an evolutionary upgrading of the Air Traffic Control Radar Beacon System (ATCRBS). DABS will provide improved surveillance and data link service to suitably equipped aircraft operating on the same ATCRBS frequencies. Questions in response to the publication of the proposed DABS National Standard in the Federal Register in March 1978 have been raised regarding the potential interference to ATCRBS because of common channel usage. The purpose of this document is to present the assumptions, models and system operation necessary to assess the potential interference effects of DABS on ATCRBS. The conclusion of the analysis presented herein is that the current ATCRBS surveillance ability will not be degraded as a result of implementing DABS. (Author)
