Analysis on the Application of Feed-Forward Technology for Space Tracking, Telemetering and Control Ships

摘要

Shipborne radar devices are influenced by ship-swaying in terms of their tracking accuracy, especially under bad sea conditions, which making it very important to employ a technique which not only maintains tracking stability but also isolates ship-swaying effects. A scheme which compensates antenna azimuth and elevation angles for feed-forward controls is proposed. First the radar ship-swaying feed-forward compensation technique is introduced, followed by feed-forward equations deduced by compensating tracking errors caused by ship-swaying and target movements. Then, the deduction results are analyzed and concluded that ship-swaying feed-forward data can be validly produced without target distance values provided.
