本发明涉及无线通信技术领域，尤其涉及一种基于移动平台的天线测试方法、装置及信息处理设备。
背景技术
天线是将传输线中的电磁能转化成自由空间的电磁波，或将空间电磁波转化成传输线中的电磁能的专用设备。目前，随着通信业务需求的增强，天线的应用场景也越来越多。不同的天线具备不同的方向图，根据天线的方向图可以获取天线的部分参数，从而可以确定天线的部分性能。
通常可以通过天线测试来获取天线的方向图。根据天线测试距离的远近，天线测试有近场测试和远场测试之分。其中，室内暗室测试就属于近场测试，在室内暗室测试天线时，需建立固定屏蔽室，搭配测试系统，通过算法实现近远场转换，对天线方向图相关数据的测试精度高。而对于某些天线，例如大尺寸天线，近场测试环境中由于空间的限制，难以使得发射天线和待测天线之间的距离满足远场条件；故测试大尺寸天线时需采用远场测试方式。目前的远场测试时需要覆盖较大的空间区域，在该较大的空间区域架设各类测试设备的成本较高且不易于管理。

具体实施方式
在本发明实施例中，对诸如大尺寸天线等待测天线进行测试时，在移动平台上(例如无人飞行器或无人车)设置发射天线，而待测天线固定于一个测试位置处；通过移动平台的移动来测试待测天线在不同的对发射天线的接收角度下的相关数据，进而采集得到待测天线的方向图相关数据(发射天线与待测天线之间的相对方位角度和在各个相对方位角度下接收到信号强度)，完成方向图的测试。无人飞行器等移动平台仅需在一定距离上围绕待测天线做圆周运动或近似的圆周运动即可，并且移动平台可以自动地规划移动轨迹，从而使得待测天线能够在不同的角度上接收到接收信号。本发明实施例大大提高了待测天线的远程测试的灵活性和便捷性，移动平台和待测天线均易于管理，对场地的 要求并不高，特别是在移动平台采用无人飞行器时，在多数地形情况下都能对待测天线进行方向图测试。具体请参阅图1，图1为本发明实施例提供的一种天线测试系统的架构示意图。如图1所示，天线测试系统包括天空端系统和地面端系统。天空端系统包括移动平台、以及该移动平台搭载的发射天线101和信号发生器102。
该移动平台可以是无人飞行器，例如无人机(Unmanned Aerial Vehicle，UAV)。该移动平台可以包括：机身103、控制设备104和动力系统105。该动力系统105安装于所述机身103，可以用于给移动平台提供飞行动力。控制设备104可以用于控制移动平台按照预先规划的目标移动轨迹进行移动。控制设备104与信号发生器102连接，信号发生器102与发射天线101连接。信号发生器102为信号源，用于生成目标信号。发射天线101用于发射所述目标信号。具体地，在移动平台按照待测平面中的目标移动轨迹移动时，控制设备104控制信号发生器102生成目标信号，并通过发射天线101发射该目标信号。
地面端系统包括待测天线(或者说接收天线)201、信号强度测试设备和信息处理设备203，以下以信号强度测试设备为频谱仪202来进行示意性说明。待测天线201可以分别与频谱仪202和信息处理设备203连接；频谱仪202与信息处理设备203连接。待测天线201可以用于接收发射天线101发射的所述目标信号。频谱仪202可以用于检测待测天线201接收到的目标信号的接收信号强度。在移动平台按照待测平面中的目标移动轨迹移动的过程中，信息处理设备203用于确定待测平面中发射天线101发射目标信号时相对于待测天线201的角度信息。信息处理设备203还用于从频谱仪202获取待测天线201在该角度信息对应角度下接收到的目标信号的接收信号强度(Received Signal Strength，RSS)，并根据该角度信息以及该接收信号强度，确定待测天线在该待测平面上的方向图。
在一个实施例中，发射天线101的发射方向朝向待测天线201。移动平台按照待测平面中的目标移动轨迹移动时，移动平台与待测天线201之间的距离保持不变；或者说发射天线101与待测天线201之间的距离保持不变。在另一个实施例中，发射天线101的极化方式与待测天线201的极化方式相同。例如，待测天线201的极化方式为水平极化，则发射天线101的极化方式也为水平极 化；待测天线201的极化方式为垂直极化，则发射天线101的极化方式也为垂直极化。
请参阅图2，图2为本发明实施例提供的一种基于移动平台的天线测试方法的流程示意图。本发明实施例中所描述的天线测试方法，应用于如图1所示的天线测试系统中，具体可以由图1所示天线测试系统中的信息处理设备来执行。
其中，信息处理设备首先确定待测天线对应的待测平面，该待测平面可以是包括待测天线所对应位置点在内的任意一个平面。该待测平面例如是包括待测天线所对应位置点在内的水平平面或者垂直平面等。然后基于待测天线的第一坐标信息、该待测平面以及远场测试条件，确定出该待测平面中的目标移动轨迹。该目标移动轨迹所指示的平面与该待测平面相同。在一个实施例中，目标移动轨迹上的各个位置与待测天线之间的距离均大于天线远场测试阈值，或者说目标移动轨迹上的各个位置与第一坐标信息所指示位置之间的距离均大于天线远场测试阈值；该天线远场测试阈值是基于远场测试条件确定的。远场测试条件指示：L>2D*D/λ。L为目标移动轨迹上的位置与第一坐标信息所指示位置之间的距离。2D*D/λ为该天线远场测试阈值，D为待测天线的辐射口径；λ为发射天线所发射的目标信号的波长。在另一个实施例中，目标移动轨迹上的各个位置与待测天线之间的距离还满足预设条件，或者说目标移动轨迹上的各个位置与第一坐标信息所指示位置之间的距离还满足预设条件。该预设条件指示目标移动轨迹上的各个位置与待测天线之间的距离，或者说与第一坐标信息所指示位置之间的距离均相等。由于目标移动轨迹上的各个位置与待测天线之间的距离均相等，则可以保证移动平台按照目标移动轨迹移动时，移动平台与待测天线之间的距离保持不变。
进一步地，信息处理设备将确定出的目标移动轨迹发送给移动平台，以使移动平台根据该目标移动轨迹进行移动。在一实施方式，信息处理设备可以通过待测天线将确定出的目标移动轨迹发送给移动平台；也可以通过信息处理设备自身配置的天线将确定出的目标移动轨迹发送给移动平台。相应地，移动平台接收信息处理设备发送的目标移动轨迹。移动平台的控制设备在检测到移动指令时，获取该目标移动轨迹，并控制移动平台按照该目标移动轨迹进行移动。在控制移动平台按照该目标移动轨迹移动的过程中，控制设备控制信号发生器 生成目标信号，并通过发射天线向待测天线发射该目标信号。目标信号对应的频段为待测天线能够接收到的频段。在一个实施例中，在控制移动平台按照该目标移动轨迹移动的过程中，控制设备可以控制信号发生器每隔预设时间间隔生成一次目标信号，并在生成目标信号之后，立即通过发射天线向待测天线发射该目标信号；控制设备也可以控制信号发生器在移动平台每移动预设距离之后生成一次目标信号，并在生成目标信号之后，立即通过发射天线向待测天线发射该目标信号。
在一个实施例中，移动平台按照该目标移动轨迹移动完成后，至少围绕待测天线对应的位置环绕了一周。移动平台按照该目标移动轨迹移动时是匀速移动的，移动平台在匀速移动时的移动速度是基于对目标信号的接收信号强度的采样频率确定的。预设时间间隔以及预设距离也是基于对目标信号的接收信号强度的采样频率确定的。对目标信号的接收信号强度的采样频率可以是一个默认值，也可以是用户预先设置的。具体地，移动平台在匀速移动时的移动速度与对目标信号的接收信号强度的采样频率之间成正比关系。也即是说，对目标信号的接收信号强度的采样频率越大，则移动平台在匀速移动时的移动速度越快。预设时间间隔所指示的时长可以为上述采样频率对应的采样周期所指示的时长；预设距离可以为上述移动速度与预设时间间隔所指示的时长相乘得到的距离。
如图2所示，本发明实施例的天线测试方法包括：信息处理设备执行S201，在移动平台移动的过程中，确定待测平面中发射天线相对于待测天线的角度信息。在移动平台按照待测平面中的目标移动轨迹移动的过程中，信息处理设备确定待测平面中发射天线发射目标信号时相对于待测天线的角度信息。在一个实施例中，信息处理设备首先确定待测天线的第一坐标信息。待测天线的第一坐标信息可以是信息处理设备的用户手动输入的，信息处理设备接收并存储用户手动输入的待测天线的第一坐标信息。也可以在待测天线所在的位置配置一个定位设备，该定位设备可以是位置传感器，用于采集待测天线的第一坐标信息；信息处理设备可以从该定位设备中获取得到待测天线的第一坐标信息。该第一坐标信息可以用于指示待测天线所处位置的经度、纬度和海拔高度。
然后，信息处理设备获取移动平台通过发射天线向待测天线发射目标信号 时的第二坐标信息。在移动平台按照目标移动轨迹移动的过程中，控制设备控制信号发生器生成目标信号，并通过发射天线向待测天线发射该目标信号时，记录发射天线向待测天线发射该目标信号时移动平台所处位置的第二坐标信息。控制设备可以从移动平台配置的定位设备中获取得到该第二坐标信息。该第二坐标信息可以用于指示移动平台所处位置的经度、纬度和海拔高度。信息处理设备可以从移动平台获取该第二坐标信息。具体地，信息处理设备向移动平台发送坐标获取指令，移动平台接收并响应该坐标获取指令，将记录的发射天线向待测天线发射目标信号时移动平台所处位置的第二坐标信息发送给信息处理设备。在一实施方式，信息处理设备可以通过待测天线向移动平台发送坐标获取指令；也可以通过信息处理设备自身配置的天线向移动平台发送坐标获取指令。移动平台可以通过发射天线向信息处理设备发送该第二坐标信息；也可以通过移动平台自身配置的天线向信息处理设备发送该第二坐标信息。
进一步地，信息处理设备根据该第一坐标信息以及第二坐标信息，确定待测平面中发射天线发射目标信号时相对于待测天线的角度信息。该角度信息用于指示待测平面中发射天线发射目标信号时所在位置，与待测天线所在位置之间的方向角；或者说用于指示待测天线接收目标信号的方向。举例来说，请一并参见图3，图3为本发明实施例提供的一种移动平台与待测天线之间的位置示意图。如图3所示，301所指示的平面为待测平面，302所指示的位置为第二坐标信息对应的位置，也即是发射天线发射目标信号时在待测平面中的相应位置；303所指示的位置为第一坐标信息对应的位置，为待测天线在待测平面中的相应位置。假设以正北方向为参考方向，从图3可以看出，在待测平面中302所指示位置位于303所指示位置的北偏西45度处。发射天线在302所指示位置向待测天线发射目标信号时，在待测平面中待测天线对应的接收目标信号的方向也为北偏西45度。
信息处理设备在执行S202时，获取所述待测天线在所述角度信息对应角度下接收到的目标信号的接收信号强度。需要说明的是，信息处理设备可以在接收到一个目标信号后同时计算接收该目标信号时的角度信息和接收信号强度。
本发明实施例中，待测天线接收到发射天线发射的目标信号之后，频谱仪可以针对待测天线接收到的目标信号进行信号强度检测，得到待测天线接收到 的目标信号的接收信号强度。信息处理设备可以从频谱仪中，获取待测天线接收到的与该角度信息对应的目标信号的接收信号强度。该接收信号强度为待测天线接收到的与该角度信息对应的目标信号的实际接收信号强度。
信息处理设备在S203中根据所述角度信息以及所述接收信号强度，确定所述待测天线在所述待测平面上的方向图。信息处理设备将第一坐标信息对应的点作为方向图中的基准点，将该角度信息所指示的方向角作为该方向图中取值点相对基准点的方向角；基于与该角度信息对应的接收信号强度，确定出取值点对应的取值数值，也即是确定出取值点在该方向角上相对基准点的距离。通过上述方式，可以确定出方向图中相对基准点的每一个方向角上的取值点的位置，从而构建得到待测天线在待测平面上的方向图。采用上述方式得到的待测天线的方向图是未结合测试环境中的路损情况确定出的方向图，也即是测试环境中待测天线在待测平面上的实际方向图。
举例来说，请参见图4，图4为本发明实施例提供的一种方向图的示意图。如图4所示，401所指示的平面为待测平面，403所指示的位置为待测天线在待测平面中的相应位置。402所指示的位置为取值点，从图4可以看出，在待测平面中402所指示位置位于403所指示位置的北偏西45度处；402所指示的取值点，或者说在待测平面中402所指示位置与403所指示位置之间的距离，用于表示待测天线在北偏西45度方向上的信号收发能力。可见，待测天线在不同方向上的信号收发能力通常不一致。
在一个实施例中，可以多次重复前文所述的步骤，以获取到待测天线接收到的与该角度信息对应的目标信号的多个接收信号强度，并基于该多个接收信号强度，确定出待测天线接收到的与该角度信息对应的目标信号的平均接收信号强度。然后根据该角度信息以及该平均接收信号强度，确定出待测天线在待测平面上的方向图。采用上述方式，可以在一定程度上避免测试环境中其他信号的干扰，得到的天线在待测平面上的方向图更加准确。
在另一个实施例中，信息处理设备首先获取与目标移动轨迹对应的路径损耗信息，然后根据该路径损耗信息以及该接收信号强度，确定出与该角度信息对应的目标接收信号强度；最后根据该角度信息以及该目标接收信号强度，确定出待测天线在待测平面上的方向图。其中，该路径损耗信息是根据标准天线 在待测平面上的标准方向图、以及标准天线设置在待测天线位置时接收到的目标信号的接收信号强度确定的。标准天线设置在待测天线位置的过程中，移动平台按照目标移动轨迹移动时通过发射天线向标准天线发射目标信号。采用上述方式得到的待测天线的方向图是结合测试环境中的路损情况确定出的方向图，也即是待测天线在待测平面上的标准方向图。
其中，获取与目标移动轨迹对应的路径损耗信息的方式可以为：将待测天线替换成一标准天线。该标准天线在待测平面上的标准方向图已知。该标准天线设置的位置与待测天线设置的位置相同，且该标准天线的天线类型可以与待测天线的天线类型相同。控制设备在检测到移动指令时，获取待测平面中的目标移动轨迹，并控制移动平台按照该目标移动轨迹进行移动；在移动平台按照该目标移动轨迹移动的过程中，控制设备控制信号发生器生成目标信号，并通过发射天线向该标准天线发射该目标信号。
进一步地，在移动平台按照该目标移动轨迹移动的过程中，信息处理设备获取该标准天线的坐标信息、移动平台通过发射天线向该标准天线发射目标信号时的坐标信息；根据该标准天线的坐标信息、移动平台通过发射天线向该标准天线发射目标信号时的坐标信息，确定待测平面中发射天线相对于标准天线的目标角度信息。然后获取待测天线接收到的与目标角度信息对应的目标信号的接收信号强度；并根据该目标角度信息以及该接收信号强度，确定出该标准天线在待测平面上的实际方向图。具体方向图确定方式可参考前文描述，此处不再赘述。进一步地，信息处理设备获取标准天线在待测平面上的标准方向图，并将标准天线的标准方向图与实际方向图进行对比，确定出与目标移动轨迹对应的路径损耗信息。该路径损耗信息用于指示从目标移动轨迹上的各个位置发射出的目标信号传输到标准天线(或者说待测天线)所在位置过程中分别产生的损耗程度。
本发明实施例在移动平台按照待测平面中的目标移动轨迹移动的过程中，确定待测平面中发射天线相对于待测天线的角度信息，并获取待测天线在角度信息对应角度下接收到的目标信号的接收信号强度，然后根据角度信息以及接收信号强度，确定待测天线在待测平面上的方向图，从而可以利用移动平台来实现天线的远场测试，增加天线远场测试的灵活性，易于对移动平台和待测天 线的管理；另外无需建设用于远场测试的专用场地，可以降低天线测试的成本。
