Control system for monopulse satellite receiver antenna - derives control error from sum and difference of at least two antenna signals and continuously monitors functionality

摘要

The system forms the sum and difference signals from the receiver signals of at least two antenna (3,4) and from these it derives the control error signal for the antenna control system (11). Additionally, the difference (UK) between the sum and difference signal is formed and displayed. USE/ADVANTAGE - Simple arrangement enables continuous functional monitoring of control system during operation.
