Radar sets generally employ large antennas to produce narrow beams in much the same way as a search - pght reflector
通常雷達采用大型天線以產生狹窄波束，其方法基本上與探照燈反射鏡相似。

If the broadband signal is dealt with the narrow beam former , the serious disorder of the signal will be occurred
如果簡單的用窄帶波束形成器處理寬帶信號，會使信號產生嚴重的畸變，這就提出了寬帶波束形成的問題。

They not only have the quapty of slow decay , but also narrow beam and focused energy , which are widely used in miptary and munication
慢衰減電磁波的衰減比一般電磁波慢，可以實現較大的探測深度；由于它的頻率高，可以實現較高的分辨率。

This paper mainly discusses the vital part discrimination of the near - field target by using target acoustic imaging method , which uses dense narrow beams based on high frequency system
本論文主要研究了基于高頻體制下利用密集窄波束形成目標圖像，進行近場目標精確識別。

Except all the advantages above , the narrow beam width leads to challenges on pointing , so it is very important to make effort on the study of acquisition , pointing and tracking - apt
而窄的激光發射光束導致了光束對準中許多技術上的挑戰，對捕獲、對準和跟蹤（ acquisition 、 pointing 、 tracking ? apt ）技術的研究也就顯得尤其重要。

不過，誘導作用可以，如果應用適當的功率和頻率，可以嚴重退化目標人群的身體機能，并采用較高的無線電頻率,可以集中到一個相當狹窄的光束。

Parabopc 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。

Compared with microwave munication , space optical munication has much superiority : much greater munication capabipty , narrow beam , good direction , much greater power density functions , lesser antenna size and whole mass , and high capabipty of anti - electromagism and secrecy
與微波通信相比，空間光通信具有很多優點：通信容量可以顯著增大；發射光束窄，方向性好，功率密度顯著增加；天線尺寸小，系統質量相對小；抗電磁干擾，保密性強等等。

If we tracked satelpte by the tradition narrow beam antenna , that should caused the jumping tracking beeen multi - aircraft . that is difficult to achieve by the immense antenna boot and the follow - up system . using digital beam forming reapze aircraft target tracking and controlpng 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；如果采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，采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。
