Doppler)频移,由于目标不是一个点,多径传揹,回波在时间轴上被犷展,波形和发射波形可態会大不相同,此外由于介质的随机性,也会造成回波信号的起伏。在主动声纳中,混响往往是主要的干扰。混响也是由发射信号产生的,它的许多方而的特件和阿波极为相似,使得抗混响相当闲难。本噪芦也是一种亚重的干扰:在本舰高速诺动时,更是如此。但是它是一个宽带信号,回波是一个窄带信号,可以利用功率谱的亲异来风分它们被动声纳是根据日标辐射的声液来检测目标的。这辐射的声波可能是目标上的声纳发射的声波,也可能是目标运动时辐射出的舰船噪声,也可能是目标引起的其它声音。目标辐射出的觑船噪声的功率漕和本舰噪声的功率都是宽带的,从功率谱上区分它们有一定的困难。但是本舰噪声和日标舰噪声在空间相关性上是不同的。可以利用空间相关性上的差异来区分它们。声纳系统的模型反映了声纳、介质和目标三者的关系。介质和目标的特性是我们无法控制的,而声纳,它的发射方式与接收方式是我们可以合理地选择的。使得它最佳地和介质、目标的特件匹配。早期的声纳系统,它的发射方式、接收方式是不变的,而介质和目标的特性却是因时、因地而异的,这就不可能实现最住地匹配。必须改变这种不变的发射方式、接牧方式,要根据当时当的介质、目标的特鉎,自动地调整发射方式、接收方式,以运到最住地匹配。这便是所谓的直适应技术。§1.2水声信号处理的发展概况市纳从它的诞生到现在有了很大的发展和变化。特别是近二十多年,更是如此。声纳的变化和水声信号处理的发展是一致的,或者说水声信号处理每出现一个新技术,都导致声纳的一次大变化。五十年代以前的声纳,发射波形是比较简单的,是一个正弦填充的方波,接收机采用窄带滤波。脉冲压缩我术的出现,导致脉冲压缩声纳逃出现,发射波形釆用线性调掘脉沖,戌者伪随机编码。在接收机中相应地出现了信号处理器(如 DELTIC系统等〕草题的声纳是利用换能器的自然方向性,用机械旋转的方法实现波束的旋转。随着换能器的越来越大、越来越笨重,机槭旋转越来越困难。利用相控阵孜术之后,可以用电的力法形成波束的旋转;还可以用电照方法同时形成多个波束,出现了多液束阵。利用信号有干扰的空间相关性的差别,将信号处理技术应用于基阵,出现了相关接收阵。由于铵收到的信号和干扰变化范围很大,给信号处埋带来困难,便出现了动态范压缩和归一化技术目前,自适应技术及各式各样的数字处理技术迣入了声纳领域。图1-2-1是目前的典型声纳发射机方框图。信号发生器的输出可具有多种形式(模拟的或数字的,正弦填充脉裨或线性调频脉冲,或几种信号同时共用),这取决了所考虑的系统的具体要求。信号发生器的犏出送到波束形成器矩阵去,波束形成器矩阵的用途是对信号进行适当的加权和延迟,以使发射阵产生所要求的声束图,将声能聚集到所要求的空间中去。程序器的用途是使多路或顺序发射同步。程序器信号束发生器形成矩臂发射阵图⊥-2-4声纳发射机户框图图1-2-2是目前的典型声纳接收机方框图。它比发射机复杂。这是由于在发射时信噪比是无限大的(或接近无限大),而在接收时,在大多数有实际意义的情况下,信噪比是小于1的。接收基阵和波束形成矩阵对应于发射机中发射基辉和波束形成矩阵。这两个基阵通常是共用的。但是波卓形成兔阵是有差别的,在发射机中,为了使发射能量最大,波東形成航阵具有最小的幅度加权。在接收机里,则使用幅度加权,抑制旁瓣或增大方向性指数。在发射机中用相控发射,在接收棚中采用自适应波束形成处理。程序器判决设舒一接收F态范信号形成矩阵和归处理器显示器昕觉指示网1-2-2声接收机了框图动态范围压缩和归一化(DRCN)与信号处理器具有共同的任务:对接收的信息进如工,以便适当地将其显示在视觉显示器或听党显示器上,或送给判决设备(可能是一个缴字计算机)。程序器是用来达到同步和自适应的。本课程的任务是介绍信号处理的基本理论及其实现方案。1.3主要符号表示x(t),f(t),g(:)等表示实信号x(扌)∫2(f),ga(t)等表示复数解析信号F()或ⅹ(的)表示实信号X(#)的频谱函数F(①)或X2(①)表示复数解析信号xa(4)的频函数Rx(℃)或R2x()或R(T)表示信号x(t)的自相关函数R2(τ)或R12(T)表示信号x(:)和y(t)的互相关函数H()表示时不变线性系统的频半响应函数h(T)表承时不变线性系统的冲激响应函数H(,t)表示时变线性系统的频率响应函数h(,T)表示时变线性系统的冲激响定函数xn}表示实信号序列Y(z)表示{x》}的z变换hn)表示线性系统刈单仕釆样序列("-k)的晌应h(n)表示线性位移不夾系统对单位采祥序列8(”)的响应正(z)裁示a(B)的之变换尸(A)表示事件A的粥率P(A.B)表不事牛丹出现条供下,惠件A出现的条件率F(a)或F(x)表示随机变量x的概率分布函数p()或P()表小陡机变量x的概率密度函数F()或F(x|y)表示条件概率分布函数Fx(妖}或F(K)衣爪随机向量X的慨率分布咝爨p()或户(x)表示随机向量X的概率密度区数px(夕(XY)表示随机向量的条件概率密度函数E〔x会具表示随机变量x的微学期望或统计平均E(x°)裘示随机变量x的n阶愿点矩E〔(x-μ)“)表示随机变量x的阶中心矩Mx(s)=Ee〕表示随机变量x的特征函数E(X)仝μx裴示数学期望或统计平均中x全FXX表示均方矩阵Vk≌EX-)(X-)2〕表示方差矩阵z(β)会E(XY-)或xy表条件均值vx()会E[(x-x)(X-x)Y=月或4y表示条件方差矩阵Mk(s)表示特征函数x(t,》或x(t)表示一维随机过程样本函数X(t,k或X(!)表示n雏随机过程样本函数EX(t,)!表示X(t,)的均值中x(t)表示X〔f,)的均方矩阵V2(t?表示X(t,k)方差矩阵φx(1,t:)表示X〔e)的相关矩阵vx(t1,f2)表示K(t,四)的协方差矩阵S(o)表示x(f:①)的功率谱第二章信号的解析表示和线性系统§2,1信号和信号分析信号信息传输系统的任务在于向接收者传輸消息。声纳是一种信息传输系统,它所传输的消息是目标的有无,日标的运动要素(距离、方向、形度……),目标的性质等。消息本身往往不便于传输,要將消忘放在某…个便于传输的物理量屮,这种带有消息的物理量叫做信号。在主动声纳中,回波的行无表示目标的有无,回波出现的方向,苌示目标的方向,回波出现的时刻反映了目标的距离,回波中多卜勒频偏反映了目标的相对速度,回波的频谱结构反映了目杯的类型。因此主动声纳中回波是信号。类似跑,日标的辐射噪声是被动声纳的信号。凡是妨碍接收者接收信号的物理量都是干扰。本翹噪声、混响、海洋噪声都是声纳的干扰。应当说明,干桄也带有消总,只不过是接收者不需要的消息。因此同一个勒理量对于这个接收者是信号,对于那一个接收者可能就是干扰。钶如编队航行时,甲觎主动声纳引起的日标回波是乙舰主动声纳的干扰,它会严重妨碍乙舰主动声纳的工作。再如对一个搜索潜艇的芦纳兵而言,本舰噪声是干扰,对一个测量本舰噪声的工作人员而言,本舰噪声是信号。由此可见,信号和干扰的差别仪仪在于接枚者是否需要。因此,研究信号的方法和工具,也适用于干扰。第二章、第三章介绍的内容既适用于信号也适用于干扰。信号的时域分析我们将信号用时间纟的函数表示,记作x(4)。如果时间连续地取值,信号叫做连续时间信号。如果时间f离散地取值,信号叫离散时间信号。在声纳系统中常见的信号有:1.脉冲信号矩形脉冲「A0≤f≤Tx(t)0其余的r它有两个参数A和TA称做脉御幅度,T称倣脉冲班度钟形脉冲x(t)=A·e(2-1-2)它也有两个叁数A和α:A称做脉冲幅虔。它是κ〔扌)的最大值。a反映了脉冲度。钟
