Prediction Model of ATCRBS Transient Effects Performance.

摘要

A pulse-by-pulse simulation of the Air Traffic Control Radar Beacon System (ATCRBS), developed by the Transportation Systems Center of the DOT, was adapted by the Electromagnetic Compatibility Analysis Center (ECAC) for use with the UNIVAC 1110 computer. The model was made more flexible by adding the capability to use automated input information about ATCRBS and aircraft deployment. A terrain mode was added so the effects of terrain on coverage can be assessed. In addition, routines were added that simulate the effects of staggered and jittered PRF's and transponder reply codes, so that near-synchronous interference problems, broken and false targets, and other time-related anomalies can be investigated. Within the scope of this project, code-data-sampling and code-validation functions of the following digital processors have been included in the simulation: ARTS III, AN/TPX-42, and the AN/FYQ-49 common digitizer.
