为使本公开的上述目的、特征和优点能更明显易懂，下文特举可选实施例，并配合所附附图，作详细说明如下。

具体实施方式
为了使本公开的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本公开进行进一步详细说明。应当理解，此处描述的具体实施例仅仅用以解释本公开，并不用于限定本公开。
在一个或多个实施例中，如图1所示，提供了一种天线校正方法，本实施例以该方法应用于终端进行举例说明，该终端可以但不限于是各种个人计算机、笔记本电脑、智能手机、平板电脑和便携式可穿戴设备。本实施例中，该方法包括以下步骤：
S110：在确定目标发射通路时，断开目标发射通路。
其中，目标发射通路存在损坏的天线阵元和/或移相器。参考图2，提供了一种天线结构，其中，信号源可以为毫米波信号源，配置成电磁波信号的发射和接收；功率分配单元具体为功率分配器(功分器)，配置成给每一发射通路分配电磁波信号；每路发射通路包括移相器和天线阵元，移相器配置成对相控阵天线进行移相，得到每个天线阵元的不同相位值，天线阵元配置成组成天线阵列，实现相控阵天线的角度扫描功能；本公开实施例中可以在每路发射通路上设置开关，配置成控制对应发射通路的导通与关断；控制模块具体可包括相位控制单元和基带控制单元，其中相位控制单元具有相位寄存功能与相位控制功能，可分别控制各移相器的状态，也可以写入各移相器的状态，基带控制单元可分别控制各开关的开与断以及功率分配单元的功分通路。示例性的，图2所示天线结构包括4路发射通路，第一路发射通路包括开关1、移相器1和天线阵元1，第二路发射通路包括开关2、移相器2和天线阵元2，第三路发射通路包括开关3、移相器3和天线阵元3，第四路发射通路包括开关4、移相器4和天线阵元4。可以理解的是，图2仅示意性地示出了一种可实施的天线结构，本公开的天线校正方法还可适用于具有更多天线阵元的天线系统。
在本公开实施例一实施方式中，确定目标发射通路，包括：
S111：控制天线中的各发射通路依次与目标基站通信。
示例性的，可通过控制各发射通路的开关，每次仅导通一路发射通路，例如参考图2，打开开关1，同时关闭开关2、开关3和开关4，第一路发射通路导通，第二路发射通路、第三路发射通路和第四路发射通路断开，如此，依次控制第二路发射通路、第三路发射通路和第四路发射通路导通，导通的发射通路可向目标基站发射电磁波信号，也可以接收目标基站发射的电磁波信号，其中，目标基站为与天线对应的终端建立通信的基站。
S112：如果任一发射通路在预设通信时间内未收到目标基站的应答，则将任一发射通路确定为目标发射通路。
其中，预设通信时间可设置为基站与终端通信时的常规响应时间。
示例性的，在导通任一发射通路时，信号源工作，如果该任一发射通路上的天线阵元和/或移相器没有损坏，通过该任一发射通路会向目标基站发射电磁波信号，目标基站接收到该电磁波信号时，会基于电磁波信号的请求进行反馈；但是，如果该任一发射通路上的天线阵元和/或移相器已损坏，便不会向目标基站发射电磁波信号，目标基站自然不会做出应答。因此，如果任一发射通路在预设通信时间内未收到目标基站的应答，则将任一发射通路确定为目标发射通路。
在确定目标发射通路时，断开该目标发射通路，避免了损坏的天线阵元和/或移相器对正常发射通路的影响。
S120：遍历剩余发射通路中各移相器的状态，得到多组移相数据以及各组移相数据对应的天线信号强度。
其中，剩余发射通路为天线中除目标发射通路之外的发射通路，天线信号强度包括天线接收到的目标基站发射的第一信号强度，或者目标基站接收到的天线发射的第二信号强度。
在本公开实施例一实施方式中，遍历剩余发射通路中各移相器的状态，得到多组移相数据以及各组移相数据对应的天线信号强度，包括：
S121：调节剩余发射通路中各移相器的移相角度，得到各移相器的移相角度的全部组合，其中，每种组合的移相角度构成一组移相数 据。
具体的，移相器的移相角度即为移相器的状态，其对应的数据为移相数据，控制模块控制调整各移相器的移相角度，而每个移相器可包括多个可调的移相角度，例如30度、60度、90度、120度、150度、180度、210度、240度、270度、300度、330度和360度，此时，每个移相器可调整12个不同的移相角度，如果剩余发射通路的数量为3个，遍历剩余发射通路中各移相器的状态即可得到12*12*12＝1728种组合。示例性的，继续参考图2，剩余发射通路包括第一路发射通路、第二路发射通路和第三路发射通路，先调整第一路发射通路和第二路发射通路中的移相器，即移相器1和移相器2的移相角度为30度，再依次调整移相器3可调的移相角度，例如移相器3的移相角度依次调整为30度、60度、90度、120度、150度、180度、210度、240度、270度、300度、330度和360度，每次与移相器1和移相器2的移相角度组成一组移相数据，之后将移相器的移相角度调整为60度，再依次调整移相器3可调的移相角度。如此，遍历剩余发射通路中各移相器的状态。
S122：分别在各组移相数据下获取天线信号强度。
示例性的，每次调整完剩余发射通路中各移相器的状态后，在对应该组移相数据下发射与接收电磁波信号，得到发射或接收的电磁波信号的强度，即天线信号强度。如此，可得到各组移相数据及其对应的天线信号强度。
考虑到终端与基站通信的互异性，即当天线接收到的目标基站发射的信号强度最强时，目标基站接收到的该天线发射的信号强度也最强。因此，可获取天线接收到的目标基站发射的信号强度或者目标基站接收到的该天线发射的信号强度，即第一信号强度或者第二信号强度。
示例性的，获取天线信号强度可包括：获取天线的信号源接收到的电磁波信号的强度，并作为第一信号强度。
或者，获取天线信号强度可包括：获取目标基站的反馈信息；基于反馈信息得到第二信号强度。该实施方式中，目标基站的反馈信息 包含目标基站接收到的天线发射的信号强度，基于该反馈信息可解析得到目标基站接收到的天线发射的信号强度，即第二信号强度。
S130：确定最大天线信号强度对应的至少一组移相数据。
在多种移相器的状态的组合下，可能存在一组或多组移相数据都对应最大天线信号强度。通过对比在各组移相数据下获取的全部天线信号强度，可确定最大天线信号强度，再基于上述实施例确定的每组移相数据与天线信号强度的对应关系，可确定最大天线信号强度对应的至少一组移相数据。
S140：基于至少一组移相数据调整对应移相器的状态，以校正天线。
示例性的，在至少一组移相数据包括多组移相数据时，可随机选取该多组移相数据中的一组移相数据，控制模块基于该组移相数据调整对应移相器的状态，从而可使第一信号强度或第二信号强度最强。
在上述实施例中，在确定具有损坏的天线阵元和/或移相器的目标发射通路时，通过断开目标发射通路，遍历剩余发射通路中各移相器的状态，得到多组移相数据以及各组移相数据对应的天线信号强度，确定最大天线信号强度对应的至少一组移相数据，基于至少一组移相数据调整对应移相器的状态。如此，将目标发射通路断开，避免了损坏的天线阵元和/或移相器对正常发射通路，即剩余发射通路的影响，再遍历剩余发射通路中各移相器的状态，得到多组移相数据以及各组移相数据对应的天线信号强度，由此可确定天线信号最强时的至少一组移相数据，进而利用至少一组移相数据调整对应移相器的状态，可将天线的通信质量调到最优，使得部分天线阵元和/或移相器的损坏不影响天线与基站的正常通信，即本公开技术方案可以在部分移相器和/或天线阵元损坏的情况下对天线进行校正，改善天线通信质量。
在本公开上述实施例的基础上，在一些实施例中，天线校正方法还可包括：仅为剩余发射通路分配电磁波信号。
可选的，调整功率分配器(功率分配单元)的功分通路，以使调整后的功分通路与所述剩余发射通路一一对应连接。示例性的，参考图2，功率分配单元为4路功率分配器，即包括4路功分通路；当剩余 发射通路为3路发射通路时，如为第一路发射通路、第二路发射通路和第三路发射通路，将功率分配单元的4路功分通路调整为3路功分通路，且分别与第一路发射通路、第二路发射通路和第三路发射通路连接。如此，可避免信号强度的损失，防止因天线的辐射较弱而导致基站接收不到信号，进一步保证终端与基站的通信质量。
在本公开上述实施例的基础上，在一些实施例中，天线校正方法还可包括：如果不存在目标发射通路或者目标发射通路没有改变，则控制各移相器的状态保持不变。
示例性的，当不存在目标发射通路，即天线的各发射通路的移相器和天线阵元均完好无损时，仍使用原来设置的移相数据来控制移相器的状态；当目标发射通路没有改变，即目标发射通路的数量和位置均未改变时，使用前一次确定的至少一组移相数据控制移相器的状态。如此，可实时保证终端与基站的通信质量最优。
另外，在本公开上述实施例的基础上，在一些实施例中，天线校正方法还可包括：仅存储最大天线信号强度对应的至少一组移相数据。如此，在后续进行天线校正时，只在该至少一组移相数据中确定最大天线信号强度对应的一组移相数据即可，避免了大量的数据处理，提高了天线校正效率。
应该理解的是，虽然图1的流程图中的各个步骤按照箭头的指示依次显示，但是这些步骤并不是必然按照箭头指示的顺序依次执行。除非本文中有明确的说明，这些步骤的执行并没有严格的顺序限制，这些步骤可以以其它的顺序执行。而且，图1中的至少一部分步骤可以包括多个子步骤或者多个阶段，这些子步骤或者阶段并不必然是在同一时刻执行完成，而是可以在不同的时刻执行，这些子步骤或者阶段的执行顺序也不必然是依次进行，而是可以与其它步骤或者其它步骤的子步骤或者阶段的至少一部分轮流或者交替地执行。
