具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
本发明的技术方案可以适用于多种天线,如双反射面天线、平板天线等,下面以具有双反射面的卡塞格伦天线为例进行说明。
图1为一种卡塞格伦天线的结构示意图,如图1所示,卡塞格伦天线由三部分组成,即主反射面、副反射面和馈源。其中主反射面为旋转抛物面,副反射面为旋转双曲面。在结构上,双曲面的一个焦点与抛物面的焦点重合 (焦点如图1中的F2所示),双曲面焦轴与抛物面的焦轴重合,而馈源位于双曲面的另一焦点上(焦点如图1中的F1所示)。卡塞格伦天线是由副反射面对馈源发出的电磁波进行的一次反射,将电磁波反射到主反射面上,然后再经主反射面反射后获得相应方向的平面波波束,以实现定向发射。
图2为本发明抵抗天线晃动的方法实施例一的流程图。如图2所示,本实施例的方法,包括:
步骤201、获取天线晃动的方向参数;所述方向参数用于指示所述天线晃动的方向和天线晃动的角度。
步骤202、控制所述天线的反射面根据所述方向参数所指示的所述天线晃动的方向和天线晃动的角度进行移动,以使所述天线的波束指向向所述天线晃动的方向的相反方向偏转。
具体来说,本实施例中首先获取天线晃动的方向参数,方向参数用于指示所述天线晃动的方向和天线晃动的角度,获取天线晃动的方向参数具体可以通过在天线上放置陀螺仪和加速度计获取天线晃动的方向和角度或者也可以通过软件的方法检测天线晃动的方向参数;控制所述天线的反射面根据所述方向参数所指示的所述天线晃动的方向和角度进行移动,以使天线波束的指向向天线晃动的方向的相反方向偏转,补偿天线晃动引起的天线方向图晃动,其中反射面包括主反射面以及副反射面。
本实施例,通过获取天线晃动的方向参数;控制所述天线的反射面根据所述方向参数所指示的所述天线晃动的方向和角度进行移动,实现了天线在晃动过程中,使天线波束的指向向天线晃动的方向的相反方向偏转,补偿天线晃动引起的天线方向图晃动,结构简单,解决了现有技术中调整结构复杂的问题。
图3为本发明抵抗天线晃动的方法实施例二的天线调整示意图一,在实施例一的基础上,本实施例中,所述控制所述天线的反射面根据所述方向参数所指示的所述天线晃动的方向和天线晃动的角度进行移动,至少包括以下两种实现方式:
第一种实现方式:
控制所述天线的副反射面朝所述天线晃动的方向偏转预设角度,其中,所述预设角度由所述天线晃动的角度确定;
第二种实现方式:
控制所述天线的副反射面朝所述天线晃动的方向偏移预设位移,其中,所述预设位移由所述天线晃动的角度确定。
具体来说,本实施例中获取天线晃动的方向参数,具体可以通过在天线抱杆(或固定在抱杆的设备上)放置陀螺仪和加速度计获取天线晃动的方向和角度或通过软件的方法检测天线晃动的方向参数;控制天线的副反射面朝所述方向偏转预设角度或偏移预设位移,以使天线波束的指向向天线晃动的方向的相反方向偏转,补偿天线晃动引起的天线方向图晃动,具体来说可以通过音圈电机(Voice Coil Motor,简称VCM)或步进电机驱动天线的副反射面朝所述方向偏转或偏移。由于VCM或步进电机具有反应迅速的特点,而且副反射面较轻,因此可以快速调整天线的波束指向,补偿天线晃动。上述预设角度由所述天线晃动的角度确定,可以为根据经验值预先设定好的预设角度与天线晃动的角度的对应关系得出,或者通过天线自身根据方向参数的变化自适应得出的;上述预设位移由所述天线晃动的角度确定,可以为根据经验值预先设定好的预设位移与天线晃动的角度的对应关系得出,或者通过天线自身根据方向参数的变化自适应得出的。
在副反射面可以放置陀螺仪和加速度计、或在副反射面可以放置角度检测或位移检测器件,在副反射面的偏转或偏移的过程中,可以在副反射面处检测副反射面移动的方向,偏转的角度或偏移的位移,是否满足天线波束的指向保持不变,使得达到天线波束的指向与天线晃动之前的指向一致的目的。
对于第一种实现方式来说,可选地,所述控制所述天线的副反射面朝所述天线晃动的方向偏转预设角度,具体包括:
控制所述副反射面绕平行于所述天线的主反射面口面的任意轴线,朝所述天线晃动的方向偏转所述预设角度;所述轴线过所述副反射面的中心点。
具体来说,如图3所示,例如副反射面以O2为旋转支点,图3中O1为馈源相位中心点,O2为副反射面几何结构的对称中心点或叫凹面锅底中心点,O3为主反射面和副反射面的焦点,通过VCM或步进电机,以通过所述旋转支点平行于Y轴的线为轴偏转角度,如图3中偏转θ1,则天线指向会向副反射面偏转的相反方向偏转。
主反射面口面指的是主反射面口径所在的平面。
可选地,所述控制所述副反射面绕平行于所述天线的主反射面口面的任意轴线,朝所述天线晃动的方向偏转所述预设角度,包括:
当所述天线晃动的方向为绕X轴逆时针旋转的方向,则控制所述副反射面通过所述副反射面的中心点绕X轴逆时针偏转所述预设角度;或,
当所述天线晃动的方向为绕X轴顺时针旋转的方向,则控制所述副反射面通过所述副反射面的中心点绕X轴顺时针偏转所述预设角度;或,
当所述天线晃动的方向为绕Y轴逆时针旋转的方向,则控制所述副反射面通过所述副反射面的中心点绕Y轴逆时针偏转所述预设角度;或,
当所述天线晃动的方向为绕Y轴顺时针旋转的方向,则控制所述副反射面通过所述副反射面的中心点绕Y轴顺时针偏转所述预设角度。
图4为为图3所示的天线调整仿真结果示意图,表1为天线调整仿真结果的数据对应关系的表格,图4为以副反射面在其中心点,通过所述中心点平行于Y轴的线为轴旋转为例仿真,主反射面口径1.2m,副反射面口径0.3m,工作频率6GHz;表1为副反射面旋转角度为不同值时的仿真结果。
表1

上述表1中,第一列为副反射面旋转角度,第二列为天线波束的偏转角度,第三列为天线的实际增益,第四列为天线的增益损失。如表1所示,当θ=6°时,天线波束指向偏向副反射面旋转的相反方向,天线波束的偏转角度为2.1°,天线的增益损失较小只有0.46dB;表1中列出一些副反射面旋转角度与天线波束的偏转角度的对应关系,天线波束的偏转角度用于补偿天线晃动的角度,该对应关系也即上述列举的副反射面旋转角度与天线晃动的角度的对应关系,从表1可以看出,若副反射面旋转角度的初始值为2°,对应 的波束偏转角度为0.7°,且方向与副反射面旋转的方向相反,那么随着副反射面旋转角度以整数倍增大,则对应的波束偏转角度也以整数倍增大。
本实施例的副反射面旋转方案的优点:天线增益损失较少,指向偏转2.8°时,增益损失仅0.85dB。
图5为本发明抵抗天线晃动的方法实施例二的天线调整示意图二。
可选地,所述控制所述天线的副反射面朝所述天线晃动的方向偏转预设角度,具体包括:
控制所述副反射面绕相互正交的两个轴线中的一轴线向所述天线晃动的方向偏转第一预设角度,并绕所述相互正交的两个轴线中的另一轴线朝所述天线晃动的方向偏转第二预设角度;所述两个轴线的交点为所述副反射面的中心点;其中,所述第一预设角度和第二预设角度由所述天线晃动的角度确定。
具体来说,控制所述副反射面绕过所述副反射面的中心点的相互正交的两个轴线,分别向所述方向偏转第一预设角度和第二预设角度,使天线波束向天线晃动的反方向摆动,达到补偿天线晃动引起的天线方向图晃动,可以补偿任意方位的天线晃动,可以通过使用两个VCM或步进电机驱动副反射面偏转。如图5所示,例如可以分别绕通过副反射面的的中心点的X轴和Y轴,向所述方向偏转第一预设角度θ1和第二预设角度θ2,第一预设角度θ1和第二预设角度θ2由所述天线晃动的角度确定,具体可以根据经验值确定或通过天线自身根据方向参数的变化自适应确定。
图6为本发明抵抗天线晃动的方法实施例二的天线调整示意图三。
对于第二种实现方式来说,可选地,所述控制所述天线的副反射面朝所述天线晃动的方向偏移预设位移,具体包括:
控制所述副反射面在平行于所述天线的主反射面口面的平面内,沿过所述副反射面的中心点的轴线朝所述天线晃动的方向偏移所述预设位移。
具体来说,通过一个VCM或步进电机驱动天线的副反射面向天线晃动的方向偏移预设位移,可以使天线的波束向天线晃动的反方向摆动,达到补偿天线晃动引起的天线方向图晃动。
可选地,所述控制所述副反射面在平行于所述天线的主反射面口面的平面内,沿过所述副反射面的中心点的轴线向所述方向偏移所述预设位移,包括:
当所述天线晃动的方向为沿X轴的方向,控制所述副反射面沿X轴偏移所述预设位移;或,
当所述天线晃动的方向为沿Y轴的方向,控制所述副反射面沿Y轴偏移所述预设位移。
如图6所示,例如副反射面在其中心点,VCM或步进电机驱动副反射面,以通过所述中心点平行于主反射面口面的面内偏移,如以图中X轴方向偏移预设位移L1,则天线指向会向副反射面偏移的反方向偏转,其中,预设位移L1由所述天线晃动的角度确定,具体可以根据经验值确定或通过天线自身根据方向参数的变化自适应确定。
图7为图6所示的天线调整仿真结果示意图,表2为天线调整仿真结果的数据对应关系的表格,图7中以副反射面在其中心点,通过中心点平行于主反射面口面的面内X轴偏移为例仿真,主反射面口径1.2m,副反射面口径0.3m,工作频率6GHz;表2为偏移的位移为不同值时的仿真结果。
表2
Figure PCTCN2014091715-appb-000002
上述表2中,第一列为副反射面偏移的位移,第二列为天线波束的偏转角度,第三列为天线的实际增益,第四列为天线的增益损失。如图7和表2所示,当偏移50mm时,天线的波束指向向副反射面偏移的反方向偏移,天线波束的偏转角度为2.7°,天线的增益损失较大,增益损失达2.58dB;表2中列出了其中一些副反射面偏移的位移与天线波束的偏转角度的对应关系,天线波束的偏转角度用于补偿天线晃动的角度,也即给出了其中一些副反射 面偏移的位移与天线晃动的角度的对应关系,从表2可以看出,若副反射面偏移的初始位移为10mm,对应的波束偏转角度为0.5°,且方向与副反射面偏移的方向相反,那么随着副反射面偏移的位移以整数倍增大,则对应的波束偏转角度也以整数倍增大。。
本实施例的副反射面偏移的方案,在天线偏移位移较小时,增益损失较小,在天线偏移位移较大时,如偏移50mm时,天线增益损失较大,此时天线波束的偏转角度为-2.7°,增益损失达2.58dB。
图8为本发明抵抗天线晃动的方法实施例二的天线调整示意图四。
可选地,所述控制所述天线的副反射面朝所述天线晃动的方向偏移预设位移,具体包括:
控制所述副反射面在相互正交的两个平面中的一平面内朝所述天线晃动的方向偏移第一预设位移,并在相互正交的两个平面中的另一平面内朝所述天线晃动的方向偏移第二预设位移;其中,所述第一预设位移和第二预设位移由所述天线晃动的角度确定。
具体来说,控制天线的副反射面在两个正交的维度面来回偏移,可以使天线的波束指向向副反射面偏移的相反方向偏转,可以使天线的波束指向向天线晃动的反方向来回摆动,达到补偿天线任意晃动引起的天线方向图晃动,可以通过两个线性电机驱动副反射面移动。
如图8所示,例如副反射面在其中心点,通过X轴、Y轴线性电机,以通过所述中心点平行于主反射面口面的平面内以及垂直于主反射面口面的平面内偏移,如以图中X轴、Y轴方向偏移,分别偏移预设位移L1、L2,则天线指向会向副反射面偏移的相反方向偏转,其中预设位移L1、L2由所述天线晃动的角度确定。
本实施例,实现了天线在晃动过程中,通过获取晃动的方向和角度,控制天线的副反射面朝所述方向移动,以使天线波束的指向向天线晃动的方向的相反方向偏转,补偿天线晃动引起的天线方向图晃动,结构简单,解决了现有技术中调整结构复杂的问题。
图9为本发明抵抗天线晃动的方法实施例三的天线调整示意图一,在实施例一的基础上,本实施例中,所述控制所述天线的反射面根据所述方向参数所指示的所述天线晃动的方向和天线晃动的角度进行移动,包括:
控制所述天线的主反射面朝所述天线晃动的方向的相反方向偏转预设角 度,其中,所述预设角度由所述天线晃动的角度确定。
具体来说,本实施例中首先获取天线晃动的方向和天线晃动的角度,具体可以通过在主反射面和抱杆(或固定在抱杆的设备上)分别放置陀螺仪和加速度计、或分别放置角度检测器获取天线晃动的方向和角度,也可以通过软件的方法检测天线晃动的方向和天线晃动的角度;控制天线的主反射面朝所述天线晃动的方向的相反方向偏转预设角度,以使天线波束的指向向天线晃动的方向的相反方向偏转,补偿天线晃动引起的天线方向图晃动,具体来说可以通过VCM或步进电机驱动天线的主反射面朝所述方向的相反方向移动。由于VCM或步进电机具有反应迅速的特点,因此可以快速调整天线的波束指向,补偿天线晃动。上述预设角度由所述天线晃动的角度确定,可以为根据经验值预先设定好的预设角度与天线晃动的角度的对应关系得出,或者通过天线自身根据方向参数的变化自适应得出的。
在主反射面和天线抱杆分别放置陀螺仪和加速度计,在天线抱杆处检测天线晃动的方向和角度,在主反射面的偏转的过程中,在主反射面处可以检测主反射面偏转的方向和角度,是否满足天线波束的指向保持不变,使得达到天线波束的指向与天线晃动之前的指向一致的目的。
可选地,所述控制所述天线的主反射面朝所述天线晃动的方向的相反方向偏转预设角度,具体包括:
控制所述主反射面绕平行于所述主反射面口面的任意轴线,朝与所述天线晃动的方向的相反方向偏转所述预设角度;所述轴线过所述主反射面的中心点。
在本发明的一种实施方式中,如图9所示,可以通过使用一个VCM或步进电机驱动天线的主反射面在俯仰面偏转预设角度θ(根据天线晃动自适应的角度),使天线波束向天线晃动的反方向旋转,其中,预设角度θ由所述天线晃动的角度确定。
例如主反射面以O4(图9中经过所述主反射面的中心点与纸面垂直的轴)为旋转轴,通过电机驱动主反射面进行旋转,则天线指向会以与主反射面旋转的相同方向进行偏转。
图10为图9所示的天线调整仿真结果示意图,表3为天线调整仿真结果的数据对应关系的表格,图10中以上述旋转轴旋转为例,对主反射面口径260mm、副反射面口径25mm的天线进行仿真分析,工作频点为78.5GHz, 主反射面旋转角度3.6°,表3为主反射面旋转角度为不同值时的仿真结果。
表3

上述表3中,第一列为工作频点,第二列为主反射面旋转角度,第三列为天线波束的偏转角度,第四列为天线的实际增益,第五列为天线的增益损失。如图10和表3所示,当主反射面偏转角θ=3.6°时,天线波束的偏转角度为3°。本实施例的主反射面旋转方案的优点:天线增益损失较少,当天线波束的偏转角度为3°时,增益损失仅0.82dB;天线的波束指向与主反射面偏转的方向一致。天线波束偏转角度用于补偿天线晃动的角度。
可选地,所述控制所述天线的主反射面朝所述天线晃动的方向的相反方向偏转预设角度,具体包括:
控制所述主反射面绕相互正交的两个轴线中的一轴线朝与所述天线晃动的方向相反的方向偏转第一预设角度,并绕相互正交的两个轴线中的另一轴线朝与所述天线晃动的方向相反的方向偏转第二预设角度;所述两个轴线的交点为所述主反射面的中心点;其中,所述第一预设角度和第二预设角度由所述天线晃动的角度确定。
具体来说,控制所述主反射面绕过所述主反射面的中心点的相互正交的两个轴线,分别向与所述方向相反的方向偏转第一预设角度和第二预设角度,使天线波束向天线晃动的反方向摆动,达到补偿天线晃动引起的天线方向图晃动,可以补偿任意方位的天线晃动,可以通过使用两个VCM或步进电机驱动主反射面偏转,第一预设角度和第二预设角度由所述天线晃动的角度确定,具体可以根据经验值确定或通过天线自身根据方向参数的变化自适应确定。
图11为本发明抵抗天线晃动的方法实施例的天线结构侧视图。
如果主反射面承受较大的风载,则会使得步进电机驱动功率大大增大。在本发明的另一实施方式中,为了解决风载问题,如图11所示,在主反射面背后增加伪主面20,伪主面20与其围边21、天线罩22构成一个保护罩,起到承受风载的作用。图11中,23为馈源,24为主反射面。
本发明实施例中的天线结构,主反射面馈源保持现有紧凑形式,馈线与主面解耦,与主反射面互不影响,馈电效率高。
本实施例,实现了天线在晃动过程中,通过获取天线晃动的方向和角度,控制天线的主反射面朝所述方向的相反方向移动以使天线波束的指向向天线晃动的方向的相反方向偏转,补偿天线晃动引起的天线方向图晃动,结构简单,解决了现有技术中调整结构复杂的问题。
图12为本发明抵抗天线晃动的方法实施例四的流程图。如图12所示,本实施例的方法,包括:
步骤1201、获取天线晃动的方向参数;所述方向参数用于指示所述天线晃动的方向和天线晃动的角度;
步骤1202、控制放置在天线发射波束一侧的透镜根据所述方向参数所指示的所述天线晃动的方向和天线晃动的角度进行移动,以使所述天线的波束指向向所述天线晃动的方向的相反方向偏转。
可选地,所述透镜包括:
平底柱形透镜、平底锅形透镜、凹面柱形透镜或凹面锅形透镜。
具体来说,透镜放置在天线发射波束的一侧,通过VCM或步进电机,在与天线口面平行的面内移动透镜,即可改变天线的波束指向,达到补偿天线晃动引起的方向图改变。
可以通过放置在天线上的陀螺仪和加速度计,在天线处检测天线晃动的方向和角度,也可以通过软件的方法检测天线晃动的方向和角度,通过自适应调整透镜的偏移位移和频率,快速补偿天线晃动引起的波束偏转,能够快速的纠正波束指向。
可以根据预先获知的透镜与所述天线口面的距离,确定放置透镜的初始位置,例如可以是经过仿真得到的最优的与所述天线口面的距离,在所述初始位置放置所述透镜。
天线口面指的是天线的反射面口径的平面。
本实施例,通过获取天线晃动的方向参数;在天线口面前放置透镜,控制所述透镜根据所述方向参数所指示的所述天线晃动的方向和角度进行偏移,以使所述天线的波束指向向所述天线晃动的方向的相反方向偏转,实现了天线在晃动过程中,补偿天线晃动引起的天线方向图晃动,结构简单,解决了现有技术中调整结构复杂的问题。
图13为本发明抵抗天线晃动的方法实施例五的天线调整示意图一,在实施例四的基础上,本实施例中,所述控制放置在天线发射波束一侧的透镜根据所述方向参数所指示的所述天线晃动的方向和天线晃动的角度进行移动,包括:
控制所述透镜朝所述天线晃动的方向偏移预设位移,其中,所述预设位移由所述天线晃动的角度确定。
具体来说,通过一个VCM或步进电机驱动所述透镜向天线晃动的方向偏移预设位移,可以使天线的波束指向向天线晃动的反方向摆动,达到补偿天线晃动引起的天线方向图晃动;其中,所述预设位移由所述天线晃动的角度确定,可以为根据经验值预先设定好的预设位移与天线晃动的角度的对应关系得出,或者通过天线自身根据方向参数的变化自适应得出的。

当所述天线晃动的方向为沿Y轴的方向,控制所述透镜沿Y轴偏移所述预设位移。
具体来说,以平底柱形透镜为例,如图13所示,例如通过VCM或步进电机驱动平底柱形透镜,在平行于天线口面的面内偏移,如以图中X轴方向偏移(箭头所示方向),则天线指向会向平底柱形透镜偏移的相反方向偏转。
