技术领域
本申请涉及通信技术领域，尤其涉及一种波束控制装置、设备以及方法。
背景技术
在一些通信系统中，如第五代移动通信系统(5th generation wireless system，5G)中，网络设备需要在上行发送或者下行接收的过程中，常基于波束赋形技术，通过相控阵系统调制相位阵列，以使一些角度的信号获得相长干涉，使另一些角度的信号获得相消干涉。
目前，相控阵系统基于延时器件(例如移相器或延时线)进行相位调整时，相控阵系统中的延时器件与天线(阵列)的一一对应，每个天线需要有一个对应的延时器件对其将要发射的信号进行相位调整，以实现波束赋形。
然而，随着通信技术的不断发展，天线规模不断提升以满足对通信质量的高要求，此种情况下，相控阵系统的延时器件的数量越来越多，导致相控阵系统的成本较高、体积较大。

应理解，本申请对于网络设备和终端设备的具体形式均不作限定。
下面对本申请设计的波束赋形进行说明：
波束赋形，又称作波束成形或空域滤波，是一种使用传感器阵列定向发送和/或接收信号的信号处理技术。通过波束赋形可以使一些角度的信号获得相长干涉，另一些角度的信号获得相消干涉。相控阵系统正是基于波束赋形技术，对规律性排列的基阵阵元的信号加以适当的移相(或延时)，使得一些角度的信号获得相长干涉，从而获得波束的偏转。
图2a为本申请提供的一种电子架构的相控阵系统200a的结构示意图。如图2a所示，相控阵系统200a包括W个移相器，W为大于1的正整数，例如移相器1至W， 相控阵系统200a中的移相器一般工作在厘米波、分米波或毫米波范围(例如波长1～200毫米)内，移相器对波长范围内的信号进行相位控制后，经过相位控制的信号分别通过W个天线发送。一方面，移相器工作的波长较大，将导致移相器的物理尺寸较大，占用较大的物理空间；另一方面，移相器可利用的频谱资源有限，无法在频域上扩展移相器的相位控制能力，导致相控阵系统200a的相位控制(也即波束控制)能力较低。
图2b为本申请提供的一种微波光子相控阵系统200b的结构示意图。微波光子相控阵系统利用微波光子技术的抗电磁干扰、重量轻、体积小、低损耗、大带宽等优势，可以替代带宽首先的电子技术满足雷达、通信系统的需求。与电子架构的相控阵系统采用移相器时实现波束赋形不同，微波光子相控阵系统200b通过如图2b所示的W个延时线(也称作光子真延时线或真延时线)，例如延时线1至W，实现延时(相位)控制，延时线可以在光波长(900～1800nm)通过对光信号的处理实现波束赋形。微波光子相控阵系统200b还包括W个光探测器，用于将经过相位控制的光信号转换为电信号，使电信号分别通过W个天线发送。
图2c为本申请实施例提供的一种微波光子相控阵系统200c的结构示意图。作为一种示例，参见图2c，微波光子相控阵系统200c中的M个激光源210c分别发射不同波长的光信号(如λ 1～λ M)，不同波长的光信号(如λ 1～λ M)分别通过M个延时线220c，实现对不同波长的光信号(如λ 1～λ M)的相位控制，进一步地，通过波分复用器230c将不同波长的光信号(如λ 1～λ M)合成为光束1，通过一个光纤或者光波导将光束1传输到远端，远端的波分解复用器240c，波分解复用器240c对光束1进行分解得到M个光信号，M个光探测器250c分别对M个光信号进行探测，将其转换为M个电信号，由天线阵列260c进行发送。
结合图2a和图2b所示，天线(或称作天线阵元、天线阵元端口、天线阵列)与延时器件(例如移相器或延时线)一一对应，即每个天线均需要有一个对应的延时器件(例如移相器或延时线)，实现波束赋形。然而，随着通信技术的不断发展，天线规模不断提升以满足对通信质量的高要求，那么相控阵系统的延时器件(例如移相器或延时线)的数量较大，导致相控阵系统的成本较高、体积较大。
针对上述技术问题，本申请实施例提供的波束控制装置以及方法，针对上述相控阵系统的延时器件(例如移相器或延时线)的数量较大的问题，在波束控制的过程中将第一光束(例如图2c中的光束1)转换为N个第二光束，并对N个第二光束进行相位控制，在对第二光束进行相位控制后，可以实现将第一光束中的M个相位不同的光信号转换为N乘M个相位不同的光信号，通过对光束进行相位控制而非对每个光信号进行相位控制，有效降低了延时器件的数量，进而降低了相控阵系统的成本和体积。
图3为本申请实施例提供的一种微波光子相控阵系统300的结构示意图。如图3所示，该微波光子相控阵系统300包括：后端微波光子功能组件310、基于微波光子的射频拉远和光束成形网络320以及光电混合集成前端330。
其中，后端微波光子功能组件310包括：数字信号处理(digital signal processing，DSP)模块、任意波形发生器(arbitrary waveform generator，AWG)(例如微波光子AWG)、微波光子上变频模块、微波光子下变频模块、数模转换(analogue-to-digitalconversion，ADC)模块(例如微波光子ADC)以及环形器。
光电混合集成前端330包括：波分复用(wavelength division multiplexing，WDM)器、光电信号转换模块、射频放大模块、放大和滤波模块、环形器。可选的，光电混合集成前端330还可以包括天线(天线阵列、天线阵列端口)。其中，波分复用器可以用于实现复用器(multiplexer，MUX)或者解复用器(demultiplexer，DEMUX)的功能。
后端微波光子功能组件310可以通过射频拉远与基于微波光子的射频拉远和光束成形网络320进行远距离通信，实现与天线物理分离。可选的，后端微波光子功能组件310可以部署于基站的地面设备，基于微波光子的射频拉远和光束成形网络320以及光电混合集成前端330可以部署与基站的塔上设备。
在上述微波光子相控阵系统300中，发射链路为：任意波形发生器根据数字信号处理模块输出的时钟控制信号，微波光子上变频模块通过电光调制将数据/基带信号与光电振荡器生成的本振信号进行上变频，经过光滤波器滤除杂散信号经射频光拉远送至光束成形网络。光束成形网络完成发射通道间的动态配置后，将光信号发送至对应的光电混合集成前端330。在光电混合集成前端330中，通过延迟线实现对光信号相位的控制，再经光电变换后恢复出射频激励信号，再经射频放大后由天线辐射。
与之对应，接收链路为：天线探测到的雷达回波信号首先进行射频预处理(如放大和滤波模块)进行放大和滤波后，通过光电信号转换模块，将电信号调制到光域，在光域通过延时线完成相应的相位控制后，经光束成形网络完成子阵级波束合成后通过射频光拉远传回后端微波光子功能组件310。在后端微波光子功能组件310中，通过微波光子下变频模块将探测到的高频信号下变频至中频，经过光学滤波、光电转换后处理中频信号，也可以利用ADC技术直接对高频信号进行带通采样。采样后的数字信号再送至数据信号处理模块完成相关信号处理。
下面将结合附图对本申请实施例提供的波束控制装置以及方法做详细说明。
图4a为本申请实施例提供的一种波束控制装置400a的结构示意图。
参见图4a，该波束控制装置400a包括第一相位控制模块410a和电信号转换模块420a。其中，第一相位控制模块410a用于将第一光束转换为N个第二光束，N为大于1的正整数，电信号转换模块420a用于将N个第二光束对应的N乘M个光信号转换为N乘M个电信号，M为大于1的正整数，该N乘M个电信号由N乘M个天线阵列发送。
需要说明的是，第一光束包括M个不同波长的光信号，且该M个光信号之间存在第一相位差。例如第一光束的M个光信号(波长λ 1～λ M)之间满足移相矩阵：[0 α … (M-1) α]，其中α为第一相位差。
可选的，第一光束可以是经过相位控制的M个光信号合成的。对第一光束进行相位控制可以是本申请中的波束控制装置400a实现的或者其他设备的相位控制模块实现的，本申请对此不做限定。
N个第二光束中第i个第二光束包括M个不同波长的光信号，i为大于0且小于N的正整数，换言之，N个第二光束中的每个第二光束均包括M个不同波长的光信号。一般来说，第二光束中的M个光信号与第一光束中的M个光信号一一对应，分别具有相同的波长，例如假设第一光束中的M个光信号的波长分别为λ 1、λ 2……λ M，第 二光束中的M个光信号的波长也分别为λ 1、λ 2……λ M。也即，第一相位控制模块将第一光束转换为N个第二光束的过程中，光束中光信号的波长不变。
例如，将N个第二光束对应的N乘M个光信号表示为
Figure PCTCN2022133327-appb-000001
对应的波长可以表示为
Figure PCTCN2022133327-appb-000002
需要说明的是，在N个第二光束中，第i个第二光束中第j个光信号和第i+1个第二光束中第j个光信号之间存在第二相位差，j为大于0且小于等于M的整数，也即S ij和S (i+1)j对应的光信号之间存在第二相位差。
在N个第二光束中，第i个第二光束中第j个光信号和第i个第二光束中第j+1个光信号之间存在第一相位差，也即S ij和S i(j+1)对应的光信号之间存在第一相位差。
例如，N个第二光束对应的N乘M个光信号应满足如下移相矩阵(1)：
Figure PCTCN2022133327-appb-000003
其中，α为第一相位差，β为第二相位差。
由此可见，第一相位控制模块可以实现将第一光束中M个相位不同的光信号转换为N个第二光束对应的N乘M个相位不同的光信号，第一相位控制模块实现了对光束进行相位控制而非对每个光信号进行相位控制，进一步地，电信号转换模块420a将N乘M个相位不同的光信号转换为电信号，并由N乘M个天线(天线阵列或天线阵列端口)发送，实现波束赋形，相比于针对每个天线需要设置对应的延时器件进行相位控制而言，有效降低了延时器件的数量，进而降低了相控阵系统的成本和体积。
可选的，图4a中的第一相位控制模块410a例如可以部署于图3中的光束成形网络，电信号转换模块420a例如可以是图3中的光电信号转换模块1。
