narrow-beam antenna 中文意思是什麼
narrow-beam antenna
解釋
窄束天線-
Parabolic antenna in a widely used is tracking antenna area, by use the optimum design, it may produce a very narrow beam, it ' s tracking precision is high, but because it ' s beam width is very narrow, the searching target is very difficult
摘要拋物面天線是火控雷達中普遍使用的一種跟蹤天線,通過系統優化設計,可以形成很窄的波束,所以其跟蹤精度很高,因為其波束很窄,所以搜索發現目標困難。 -
If we tracked satellite by the tradition narrow beam antenna, that should caused the jumping tracking between multi - aircraft. that is difficult to achieve by the immense antenna boot and the follow - up system. using digital beam forming realize aircraft target tracking and controlling should be best means to resolve this problem
隨著我國多星測控系統的發展,在一個測控站作用范圍內將出現多星,同時要求地面站對多星同時進行跟蹤測控;如果採用傳統的窄波束天線對目標進行跟蹤測控,必然導致天線在多個飛行器之間進行跳動跟蹤,這對于龐大的天線引導、伺服系統來說難以實現,採用數字波束對飛行器目標進行跟蹤測控是解決此問題的最好方法。
