Interference Potential of the Discrete Address Beacon System (DABS) Provisional Signal Formats on X and Y Mode TACAN Equipments.

摘要

The interference potential of newly-developed Discrete Address Beacon System (DABS) signal formats upon the performance of TACAN/DME equipment is investigated. This study is based upon information from an equipment test program conducted by ECAC in FY 74, involving several candidate DABS formats. Interference effects of the DABS signals on TACAN performance are described in terms of (1) average DABS signal level received by a TACAN interrogator, relative to the maximum interference level which several can be tolerated by the interrogator, and (2) the percent of deadtime and loading generated by the TACAN beacon as a result of DABS interference. A set of minimum frequency-distance separations that would limit the impact of DABS signal formats on the performance of TACAN equipments is developed. (Author)
