◇窄波束天线 narrow beam antenna
Examples
- 1n thi s paper we bring forward a new p1an for array miniaturization using the p1ane phase - - contro11ed array can achieve both large covering width and narrow beamwidth
本论文提出一种小型化的方案，采用平面相控阵可以实现大的覆盖宽度和窄波束。 - 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
本论文主要研究了基于高频体制下利用密集窄波束形成目标图像，进行近场目标精确识别。 - 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
随着我国多星测控系统的发展，在一个测控站作用范围内将出现多星，同时要求地面站对多星同时进行跟踪测控；如果采用传统的窄波束天线对目标进行跟踪测控，必然导致天线在多个飞行器之间进行跳动跟踪，这对于庞大的天线引导、伺服系统来说难以实现，采用数字波束对飞行器目标进行跟踪测控是解决此问题的最好方法。 - Smart antenna has been widely researched in communication and signal processing , the adaptive beamforming algorithm is the key technique of smart antenna . it could adaptively steer the array directional pattern to form the main narrow beams with high gain in the direction of the users " signals while deeply nulling the interference signals . it is an effective way to realize the optimal receiving of the interesting signals
智能天线技术是目前通信和信号处理等领域的研究热点，自适应波束形成算法的研究是智能天线的一个关键技术，它能够自适应地控制天线阵方向图在用户信号方向产生高增益窄波束，在干扰信号方向产生较深的零陷，是实现用户信号最佳接收的有效方法。
