为了方便理解，以下对本申请实施例涉及的一些内容进行说明：
一、通感一体化：
未来移动通信系统例如超5代(Beyond 5th Generation，B5G)系统或6G系统除了具备通信能力外，还将具备感知能力。感知能力，即具备感知能力的一个或多个设备，能够通过无线信号的发送和接收，来感知目标物体的方位、距离、速度等信息，或者对目标物体、事件或环境等进行检测、跟踪、识别、成像等。未来随着毫米波、太赫兹等具备高频段大带宽能力的小基站在6G网络的部署，感知的分辨率相比厘米波将明显提升，从而使得6G网络能够提供更精细的感知服务。典型的感知功能与应用场景如表1所示。
表1

通信感知一体化即在同一系统中通过频谱共享与硬件共享，实现通信、感知功能一体化设计，系统在进行信息传递的同时，能够感知方位、距离、速度等信息，对目标设备或事件进行检测、跟踪、识别，通信系统与感知系统相辅相成，实现整体性能上的提升并带来更好的服务体验。
通信与雷达的一体化属于典型的通信感知一体化(通信感知融合)应用，在过去，雷达系统与通信系统由于研究对象与关注重点不同而被严格地区分，大部分场景下两系统被独立的研究。事实上，雷达与通信系统同样作为信息发送、获取、处理和交换的典型方式，不论工作原理还是系统架构以及频段上存在着不少相似之处。通信与雷达一体化的设计具有较大的可行性，主要体现在以下几个方面：首先，通信系统与感知系统均基于电磁波理论，利用电磁波的发射和接收来完成信息的获取和传递；其次，通信系统与感知系统均具备天线、发送端、接收端、信号处理器等结构，在硬件资源上有很大重叠；随着技术的发展，两者在工作频段上也有越来越多的重合；另外，在信号调制与接收检测、波形设计等关键技术上存在相似性。通信与雷达系统融合能够带来许多优势，例如节约成本、减小尺寸、降低功耗、提升频谱效率、减小互干扰等，从而提升系统整体性能。
根据感知信号发送节点和接收节点的不同，分为以下6种感知链路，如图2所示。值得注意的是，图2中每种感知链路都以一个发送节点和一个接收节点作为例子，实际系统中，根据不同的感知需求可以选择不同的感知链路，每种感知链路的发送节点和接收节点可以有一个或多个，且实际感知系统可以包括多种不同的感知链路。图2中的感知对象以人和车作为例子，实际系统的感知对象将更加丰富。
1)基站回波感知。这种方式下基站发送感知信号，并通过接收该感知信号的回波来获得感知结果。
2)基站间空口感知。此时，基站2接收基站1发送的感知信号，获得感知结果。
3)上行空口感知。此时，基站接收终端(UE)发送的感知信号，获得感知结果。
4)下行空口感知。此时，UE接收基站发送的感知信号，获得感知结果。

二、双基地雷达：
雷达按发射机和接收机是否分置可分为单基地雷达和双/多基地雷达，双基地雷达一 般要求发射和接收天线距离很远，与雷达作用距离可比拟。其中，外辐射源雷达是双基地雷达的一种特例，利用相关的电磁波探测理论技术与信号处理技术，获取第三方(例如通信基站)发射的非合作电磁信号，实现对目标的探测、定位、跟踪和识别，又叫做无源雷达、双/多基地无源雷达、被动雷达、非合作照射源雷达或非合作无源探测系统。
双基地雷达感知结果计算一般需要基于参考信道(直达径)信号和监测信道(反射径)信号，如图3所示。以距离和多普勒计算为例，双基地雷达测得的距离为(RT+RR)＝2a＝cΔτrt+L＝cΔτt，即确定目标位置为椭球面上的某一点。其中c为光速，Δτrt为接收到直射路径信号与目标反射路径信号的时间差，Δτt为目标反射径对应的绝对时延(适用于收发时钟同步的情况),RT为发端到目标距离，L为基线距离，θR为接收端观察角度。双基地雷达由于目标运动带来的多普勒频移可以表示为
其中，λ为波长，fc为中心频点，β为双基地角，v为目标对象的运动速度，δ为目标对象的运动方向与双基地平分线的夹角，RR为目标对象到收端的距离。

示例一，第一信号(参考信道信号)和第二信号(监测信道信号)使用不同的波束赋形向量进行波束赋形，第一信号使用指向终端方向的波束发送，第二信号使用指向感知区域的波束发送，终端根据第一信号和第二信号的配置信息接收第一信号和第二信号后，进行信道估计得到信道响应信息H1(第一信道信息)和H2(第二信道信息)，进一步地，根据所述信道信息得到第一信息。
这里，假设第一信号、第二信号对应时频域资源为N个OFDM符号和M个子载波，则H1和H2矩阵规模为M*N(行对应时域、列对应频域)。假设目标感知区域中存在单个移动目标，则根据H1，沿频域维度进行IFFT计算可以得到参考信道时延域信息(以单个OFDM符号为例)，如第一信号最强径/首达径的时延值为τ1＝20.35(ns)；根据H2，沿频域维度进行IFFT计算可以得到参考信道时延域信息(以单个OFDM符号为例)，如第二信号最强径的时延值为τ2＝315.4(ns)；则第一信号最强径/首达径和第二信号最强径之间的时延差为△τ＝295.05(ns)。需要注意的是，终端上报的可以是实际时延信息的量化结果，也可以是沿频域进行IFFT后满足条件的径(最强径或者强度超过预设路径强度门限的径)对应的索引值。
同理，根据H1，沿时域维度进行DFT/FFT计算可以得到参考信道多普勒域信息(以单个子载波为例)，如第一信号最强径/首达径的多普勒频移值为26.67(Hz)；根据H2，沿频域维度进行IDFT/IFFT计算可以得到参考信道时延域信息(以单个子载波为例)，如第二信号最强径的多普勒频移值为315.4(Hz)；则第一信号最强径/首达径和第二信号最强径之间的多普勒频移差为288.73(Hz)。需要注意的是，终端上报的可以是真实多普勒信息的量化结果，也可以是沿时域维度进行DFT/FFT后满足条件的径(最强径或者强度超过预设路径强度门限的径)对应的索引值。
对于角度信息(多接收天线)计算类似，基于不同天线的信道信息H1和H2，通过沿天线维度的DFT/FFT运算或MUSIC等超分辨率算法进行计算即可得到角度信息，如第一信号最强径/首达径的到达角度为0.9°；第二信号最强径的到达角度为58.2°；则第一信号最强径/首达径和第二信号最强径之间的到达角度差为57.3°。可以理解，此处计算的角度信息为接收机本地坐标系下的角度信息，第一信息中的角度信息可以是本地坐标系下的角度信息，也可以是转换为全局坐标系下的角度信息。
也可以是基于对H1和H2进行二维DFT/FFT运算得到时延-多普勒域信息，进而得 到所述第一信息中的时延、多普勒测量结果；或者基于对H1和H2进行三维DFT/FFT运算得到时延-多普勒-角度域信息，进而得到所述第一信息中的时延、多普勒和角度测量结果。
进一步地，目标对象相对于第一设备(接收机)距离和相对于第三设备(发射机)距离之和，再减收发机距离，可以根据时延信息(第一信号和第二信号到达时间差△τ)计算：RT+RR-L＝△τ*c(c为光速)；目标对象相对于接收机距离可以根据时延和角度信息计算：θr为目标对象相对于接收机的角度。
已知第一信号、第二信号离开角度，结合第一信号、第二信号到达角度可以进一步计算出双基地角β；根据双基地角和多普勒频移以及公式 可以计算得到目标对象相对于双基地平分线的速度v*cosδ。进一步地，根据目标运动方向的先验信息或者通过多次测量得到目标运动方向信息，可以进一步得到目标对象的实际运动速度v。
需要注意的是，该示例为举例说明，具体采用的计算方法不做限制。
示例二、第一信号(参考信道信号)和第二信号(监测信道信号)使用不同的波束赋形向量进行波束赋形，第一信号使用指向终端方向的波束发送，第二信号使用指向感知区域的波束发送，终端根据所述信号配置信息接收第一信号和第二信号后，进行信道估计得到信道响应信息H1(第一信道信息)和H2(第二信道信息)，在时频域维度逐个元素求H2和H1的商，即H2./H1(或者求H2和H1共轭乘的结果，H1中各个元素取共轭然后与H2逐个元素相乘)，根据所述信道响应信息的商或共轭乘进行计算得到第一信息。
假设第一信号、第二信号对应时频域资源为N个OFDM符号和M个子载波，则H1、H2以及H2./H1矩阵规模为M*N(行对应时域、列对应频域)。假设目标感知区域中存在单个移动目标，则根据H2./H1，沿频域维度进行IDFT/IFFT计算可以得到参考信道时延域信息(以单个OFDM符号为例)，如终端上报的第一信息中的时延值为295.1(ns)(H2./H1对应的最强径或强度超过预设路径强度门限的径的时延值)。需要注意的是，终端上报的可以是真实时延信息的量化结果，也可以是沿频域进行IDFT/IFFT后满足条件的径(最强径或者强度超过预设路径强度门限的径)对应的索引值。
同理，根据H2./H1，沿时域维度进行DFT/FFT计算可以得到参考信道多普勒域信息(以单个子载波为例)，如终端上报的第一信息中的多普勒频移值为293.3(Hz)(H2./H1对应的最强径或强度超过预设路径强度门限的径的多普勒频移值)
也可以是基于对H2./H1进行二维DFT/FFT运算得到时延-多普勒域信息，进而得到所述第一信息中的时延、多普勒测量结果，如终端上报的第一信息中的时延值为295.1(ns)，多普勒频移值为293.3(Hz)(H2./H1对应的最强径或强度超过预设路径强度门限的径的时延值和多普勒频移值)。
对于角度信息(多接收天线)计算类似，基于不同天线对应的H2./H1，通过沿天线维 度的DFT/FFT运算或MUSIC等超分辨率算法进行计算即可得到角度信息，如终端上报的第一信息中的到达角为-57.7°(H2./H1对应的最强径或强度超过预设路径强度门限的径的到达角度)。可以理解，此处计算的角度信息为接收机本地坐标系下的角度信息，第一信息中的角度信息可以是本地坐标系下的角度信息，也可以是转换为全局坐标系下的角度信息。
也可以是基于对H2./H1进行二维DFT/FFT运算得到时延-多普勒域信息，进而得到所述第一信息中的时延、多普勒测量结果；或者基于对H2./H1进行三维DFT/FFT运算得到时延-多普勒-角度域信息，进而得到所述第一信息中的时延、多普勒和角度测量结果。
需要注意的是，该示例为举例说明，具体采用的计算方法不做限制。
还需要说明的是，该实施例中，目标信号可以是：基于第一信号得到的第一信道信息，基于第二信号得到的第二信道信息，或者是第一信道信息和第二信道信息的商或共轭乘的结果。
