Study of ATCRBS Data Transfer over Existion RML Equipment

摘要

Collins Radio Company has prepared this report in response to Contract ARDS-631 and the attachments thereto. The purpose of this study program is to furnish FAA evaluating engineers with data relative to the Beacon Video Channel performance of FAA RML-4 Radar Microwave Link systems.nAccordingly, a test system consisting of RML-4 terminal and repeater equipment was assembled and evaluated. The test methods, equipment used, and the acquired data are contained in this report.nDetailed beacon video channel performance data is presented herein with particular emphasis on the performance characteristics when the system is loaded with pulse trains corresponding to 4096 Beacon Codes. In ad¬dition, these tests were made under simulated "in the field" conditions such that the acquired data would represent practical system performance rather than performance in a laboratory environment. A brief investiga¬tion was also performed to evaluate the system video performance as a function of microwave frequency drift.
