在一些实施例中，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。
其中，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，典型的双基地雷达架构示意图如图3所示。其中，RT为信号发射端(Transmit，Tx)到目标距离，RR为信号接收端(Receive，RX)到目标距离，L为基线距离，θT为目标相对于信号发送端的角度，θR(θR1、θR2)为目标相对于信号接收端的角度，β为双基地角。
在一些实施例中，对于感知测量，感知分辨率与信号资源长度(带宽)关联，可以如下存在如下至少一项关联：

最大不模糊多普勒Rmax和时域资源间隔ΔT的关系为：
最大不模糊速度vmax和时域资源间隔ΔT的关系为：对于单基地感知，该速度可以为径向速度；对于双基地感知，该速度可以为双基地平分线上的投影速度，λ为信号波长，β为双基地角。
也就是说，当信号的频域资源间隔超过一定值时会发生测距模糊，时域资源间隔超过一定值时会发送测速/测多普勒模糊。
ZC(Zadoff-Chu)序列具有如下特性：
恒包络特性：任意长度的ZC序列在时域和频域都具有恒包络的理想特性，因此，ZC序列具有极佳的峰均功率比(Peak to Average Power Ratio，PAPR)和立方度量(Cubic Metric，CM)特性。
理想的周期自相关特性：任意ZC序列移位n位后，n不是ZC序列的周期的整倍数时，移位后的序列与原序列不相关。
良好的互相关特性：序列长度相同时，两个根序列号互质的ZC序列，或者两个根序列号之差的绝对值与序列长度互质的ZC序列具有良好的互相关特性，互相关峰值很低。
傅里叶变换后仍然是ZC序列：任意ZC序列经过傅里叶正反变化后仍然是ZC序列。
在一些实施例中，ZC基序列生成公式如下：
其中，NZC为质数，q为根序列号索引。
ZC序列长度为质数时，能够得到最具有良好互相关特性的序列。

其中，表示承载目标信号的相邻子载波偏移参数，即间隔的子载波个数；或者表示为：Ntotal＝NRB·ρf，其中ρf表示目标信号频域密度，即每个RB内用于承载第一信号的子载波个数。
该实施方式中，ZC序列的长度小于或者等于用于承载所述目标信号的频域资源单元总数的最大质数，这样可以使得在用于承载所述目标信号的频域资源内尽量可能传输更长的序列，以提高目标信号的传输性能。

需要说明的是，本实施例作为与图4所示的实施例中对应的第二设备的实施方式，其具体的实施方式可以参见图4所示的实施例的相关说明，以为避免重复说明，本实施例不再赘述。
下面以测量为感知为例，通过多个实施例对本申请实施例提供的方法进行举例说明：
实施例一：
本实施例主要对质数长度的ZC序列生成和频域映射举例说明。
假设ZC序列在频域采用连续映射，根据感知需求中的距离分辨率需求确定所需的目标信号带宽，例如需要调度的目标信号RB个数为NRB＝273，进而计算出总子载波个数为进而计算出ZC序列长度为不超过Ntotal的最大质数，即NZC＝3271。
确定ZC序列的根序列号，根序列号q的取值可以是{1,2,…,3270}中的一项，其具体取值与申请方案中所述感知业务相关信息，设备信息，时、频域资源相关信息、空域资源相关信息、第一序列标识中的至少一项关联，具体其计算方式可参考实施例三。
根据ZC基序列生成公式生成ZC基序列：
确定ZC序列的循环移位因子α，所述循环移位因子α的取值是α＝∈[0,2π)，其具体取值与申请方案中所述感知业务相关信息，设备信息，时、频域资源相关信息、空域资源相关信息、序列标识中的至少一项关联，具体其计算方式可参考实施例三。
根据循环移位因子α对生成ZC基序列进行循环移位得到所述质数长度ZC序列：
r(n)＝ejαnxq(n)，n＝0,1,2,…,NZC-1
其中，上述公式中的n也表示为m。
根据ZC序列的长度和频域资源确定其频域映射位置，ZC序列映射采用中心对称的频域资源映射方式，序列占用中心部分的子载波。其中，频域起始位置k0(即相对于频域参考位置，例如所述调度的273个RB的起始RE(RE0)的偏移量)为：
或
其中，NRB＝273为系统分配的用于承载目标信号的RB数，为每个RB中的子载波个数，一般取表示对X进行向下取整，表示对X进行向上取整。
假设计算得到的频域起始位置
序列中第i个元素r(i)映射到的RE索引可以表示为ki＝k0+i，i＝0,1,2,…,3270，即对质数长度ZC序列采取如图7所示的方式进行频域映射，得到所述目标信号。
假设ZC序列在频域采用非连续映射，根据感知需求中的距离分辨率需求确定所需的目标信号带宽，例如需要调度的目标信号RB个数为NRB＝273；根据感知需求中的最大无模糊距离要求确定所述的目标信号最大频域资源间隔根据所述最大频域资源间隔(和频分复用的序列个数或频分复用的CDM组数(不同CDM组占不同频域资源)、或目标信号端口数)确定承载目标信号的相邻子载波偏移参数或者也可以表述为频域密度ρf＝3，或者表述为采用comb4，即梳状映射参数Kcomb＝4。
可选地，一般取若需要支持频分复用的序列个数或频分复用的CDM组数小于也可以取例如需要支持的频分复用的序列个数或频分复用的CDM组数为2，则取即需要保证所述频域资源间隔不大于最大频域资源间隔，且能够满足支持的频分复用序列个数或目标信号端口数。
以为例，计算出所述总子载波个数为进而计算出ZC序列长度为不超过Ntotal的最大质数，即NZC＝819。
根据ZC序列生成公式生成长度为NZC的序列r(n)，n＝0,1,2,…,818，计算其频域映射位置，即频域起始位置k0(即相对于频域参考位置，例如所述调度的273个RB的起始RE(RE0)的偏移量)为：
序列中第i个元素r(i)映射到的RE索引可以表示为i＝0,1,2,…,818，即对长度NZC＝819的ZC序列采取如图8所示的方式进行频域非连续映射，得到所述目标信号。
质数长度的ZC序列以及基于循环扩展的ZC序列生成的感知信号的性能对比如图10所示。采用NZC＝3271，(即频域连续映射)的配置，按照实施例中提供的方法生成目标信号，通过循环扩展生成MCC＝3276长度的ZC序列并连续映射到频域资源上，作为对比信号。
假设环境中存在两个不同的感知目标，采用两个根序列号不同的ZC序列用于两个目标的感知，根据仿真结果可以看出，采用本申请方案生成的信号具有更好的感知性能(时延、多普勒、角度、位置坐标均方根误差(Root Mean Square Error，RMSE)更低)。即采用本实施例提供的目标信号进行感知时，对于多用户感知或多端口感知，或同时感知多个区域或目标的场景，由于保留了ZC序列的理想互相关特性，能够有效减小不同信号资源间的干扰，提升感知性能，此外相比于对ZC基序列进行循环扩展或截短的方法，具有更好的PAPR特性。
实施例二：
本实施例主要描述根据参数配置索引确定ZC序列特征。
在实际应用中，ZC序列的长度可以是按照实施例一种的流程灵活计算的，或者也可以是协议定义几种典型ZC序列长度，当需要进行感知测量时，根据所述感知需求选择合适的ZC序列长度，所述典型ZC序列长度包括以下至少一项：131，271，541，811，1091，1637，3271。或者，所述ZC序列长度包括以下至少一项：139，571，839，1151，1637，3271。
一种实现方式是，所述ZC序列默认采用连续映射的方案，即保证在当前子载波间隔配置下能够实现最大的无模糊距离测量范围，不同长度的ZC序列对应不同的目标信号带宽，用于满足不同的感知距离分辨率需求，可以根据具体的感知业务或者感知业务需求确定选用的ZC序列长度，例如上述表3所示。
另一种实现方式是，所述ZC序列默认占全带宽资源，即保证在当前子载波间隔配置下能够实现最高的距离分辨率，不同长度的ZC序列对应不同的频域资源单元间隔，用于满足不同的最大无模糊距离需求或多用户/多端口频域资源复用需求，例如上述表4所示。其中，所述多用户/多端口频域资源复用需求与支持的频分复用序列个数关联。
实施例三：
本实施例主要描述ZC序列根序列号和循环移位因子的计算。
本实施例中ZC序列根序列号或循环移位因子与感知业务相关信息、设备信息、时频域资源相关信息、空域资源相关信息、ZC序列的长度NZC、序列标识中的至少一项关联。
其中，上述序列标识可以是系统根据感知业务相关信息，设备信息，时频域资源相关信息、空域资源相关信息中的至少一项确定的。例如：根据不同感知区域、或不同基站/小区ID确定不同的第一序列标识分配给目标信号生成和发送设备。例如，根据小区ID确定的低X比特，根据感知区域ID确定的高Y比特。
根序列号q的计算可以是：
其中，u∈{0,1,…,umax}是组号，v∈{0,1}是组内序列号。
其中，N1是与最大组号umax或ZC序列长度NZC关联的正整数，例如，umax＝29，N1＝31；或者，umax＝59，N1＝61或67；或者，umax＝89，N1＝97；或者，umax＝119，N1＝127或139；或者，umax＝149，N1＝151或157；或者，umax＝179，N1＝181或191；
上述举例说明中，支持的序列组数最大为180组(umax＝179)，以此类推，还可以支持更多的序列组数，其中最大组号满足N1为大于umax且小于NZC的质数。
在实际应用中，所述组号u和组内序列号v可以是按照一定规则计算得到的，其计算方式可以是根据感知业务相关信息，设备信息，时、频域资源相关信息、空域资源相关信息中的至少一项关联。
例如：根据时域资源相关信息和目标信号索引计算得到： 其中，l′表示符号索引，可以是指时隙内符号索引，此时为每个时隙的符号个数，或所述相干处理时间窗口/感知资源块内符号索引，此时为每个相干处理时间窗口/感知资源块的符号个数；
为组跳参数，当高层参数指示开启组跳时，其中为子载波间隔配置为μ时无线帧内的时隙索引，为每个时隙的符号个数，l′指时隙内符号索引，即当前承载目标信号的符号索引；或者是当高层参数指示开启组跳时， 其中nwin为相干处理时间窗口/感知资源块索引，为每个相干处理时间窗口/感知资源块的符号个数，l′指相干处理时间窗口/感知资源块内符号索引，即当前承载目标信号的符号索引；当高层参数指示不开启组跳时，
组内序列号v的计算方式可以是，当高层参数指示开启序列跳时，或当高层参数指示不开启序列跳时，v＝0。当组跳和序列跳均不开启时，此时不同符号采用相同的ZC基序列。
其中，c(n)为PN序列元素，根据以下公式生成PN序列：
c(n)＝(x1(n+NC)+x2(n+NC))mod2
x1(n+31)＝(x1(n+3)+x1(n))mod2
x2(n+31)＝(x2(n+3)+x2(n+2)+x2(n+1)+x2(n))mod2
其中，n＝0,1,...,MPN-1，MPN为序列长度。NC＝1600，第一个m序列x1(n)的初始化方式为x1(0)＝1,x1(n)＝0,n＝1,2,...,30；第二个m序列x2(n)的初始化方式为：
又或者，不对根序列号进行分组，例如确定ZC序列长度NZC后，确定可以使用的根序列号集合q∈{1,2,…,NZC-1}，采用如下公式计算根序列号： 其中x为正整数；或者， 或其中nport为端口索引，y为正整数，即不同端口采用不同的根序列号，生成不同的ZC基序列。
循环移位值的计算方式可以是其中，表示最大循环移位值，表示生成ZC序列采用的循环移位值。可以是，根据感知区域或感知距离范围，确定最大循环移位值具体地，对于单基地感知，需要使所述感知区域或感知距离范围对应的最大目标时延小于其中Δτ为时延分辨率。对于双基地感知，需要使所述感知区域或感知距离范围对应的最大目标时延与LOS径或首达径时延之差小于即需要考虑循环移位值对时延估计的限制。
在实际应用中，可以配置多个最大循环移位值例如包括1,2,4,6,8,12中的至少一项。确定最大循环移位值后，所述生成ZC序列采用的循环移位值 或，可以是根据感知业务相关信息，设备信息，时、频域资源相关信息、空域资源相关信息中的至少一项确定的，例如当所述ZC序列采用连续映射时，即不支持不同端口信号频分复用时，其中nport为端口索引，为总端口数；又例如当所述ZC序列采用非连续映射时，即支持不同端口信号频分复用时，即此时采用相同循环移位的端口对应的ZC序列映射到不同的频域资源上，映射到相同频域资源的不同端口对应的ZC序列的循环移位值不同。
本申请实施例中，对于感知业务中可以不对序列长度进行严格限制，只需ZC序列长度满足感知所需带宽即可，从而使得感知信号资源分配可以更加灵活，使得能够使用质数长度的ZC序列以获得更好的PAPR性能以及互相关性能，可以有效提升感知性能。
