The main job and contribution of this paper are as follows:Based on narrowband signal processing, we propose a new method for FH signal blind detection and blind parameter estimation. Firstly, compute the cross-correlation function of FH signals from multichannels, then we get the cross power spectral density matrixCSDM Secondly, select the hops of FH signals from the CSDM via processing and analyzing the CSDM, meanwhile reduce the influence coming from noise, fixed frequency signal and other interferences; Lastly, estimating the DOA of every hop and according to the DOA, we can separate the hops, get the number of FH signals and their parameters. Propose a new method for designing the threshold in FH signal detection. This method makes it easy to get the threshold by theoretic computing and it can extremely reduce the interference of non-FH signals.Based on broadband signal processing, we propose a new method for FH signal blind detection and blind parameter estimation. Firstly, get the DOA of the signals by wideband spatial spectrum estimation; secondly, separate the signals by spatial filtering using wideband beamformer; Lastly, we propose two methods for FH signal blind detection and blind parameter estimation, one is for several constant hop-rate FH signals whose dwell-time are different and another is for a single FH signal whose hop-rate is alterable.By employing spatial interpolation in broadband signal beamforming, it can reduce the number of antenna elements and corresponding RF modules, A/D converters, etc. It can also eliminate the mutual coupling between antenna elements while getting the narrower main beamwidth and lower sidelobe level.

本文的主要研究工作和贡献如下：●提出了一种基于窄带处理的FH信号盲检测和参数盲估计的实现方法，即首先求出多路信号之间的互相关，进而得到互功率谱密度矩阵，然后通过对CSDM进行对折处理来抑制噪声、定频信号及其他干扰的影响，并将所有属于FH信号的hop(每一跳的驻留时间在时频图上持续的线段)从CSDM中筛选出来，最后用阵列信号处理中的到达方向估计理论在频域中估计出各个hop的方向参数，利用方位信息完成FH信号分离并得到FH信号的数目及其各自的参数集；●提出了一种确定FH信号检测门限的策略，该策略不仅使得检测门限能够通过理论计算得到，而且还显著地抑制了非跳频信号的干扰，从而能有效地检测出FH信号；●提出了一种基于宽带处理的短波FH信号盲检测和参数盲估计的实现方法，即首先利用宽带空间谱测向技术得到接收信号的DOA，然后采用宽带波束形成技术对特定方向进行空间滤波，实现多个信号的分离，最后分别提出了两种FH信号的盲检测和参数盲估计方法，第一种方法适用于空间某个特定方向上存在着几个驻留时间不同的恒跳速FH信号和其他干扰信号的混合信号，第二种方法适用于空间某个特定方向上仅含一个可变跳速的FH信号和噪声的混合信号；●将空间插值的概念和宽带波束形成技术结合起来，提出了一种基于频域处理的宽带恒定束宽的波束形成方法。

But circumstances inside the Wang Jia Wei film displays one kind sometimes all in linearity time going over and future hanging to purchase state , that often is able to point out solar terms in event beginning in image "hooligan formal biography " in famous show opening,"Chongqing tells the sum the "east evil west is poisonous to the date relapse in forest "" despite of he uses detail to go to emphasize the time concept unceasingly,these stories that he gives an account of and not special time background, they may may happen within this city corner every day, They whip the specimen being away from out in life only from the city But that you only are capable to do some detail discovering two stories is each other alternative in fact , Wang Jia Wei uses this to play hide-and-seek coming to bring about one kind of synchronic sex effect dyadic game if you had looked at "Chongqing forest " carefully,chance and nothing order having shown the present age city life now that the linearity time concept having dispeled tradition narrating is protruding, the intention having formed one kind of dyadic spirit of existentialism thereby accumulates, Wang Jia Wei applying on space is more than time benefits by associating together, If you have looked at Wang Jia Wei's work but have moved, that is by no means since are what the overall world impression initiates, but being resonance because of detail, is fragmentary as well as atmosphere called up by the subjective soliloquy that the garrulity spends can let you produce mental conception makes

王家卫电影里的场景往往都在线性时间的过去和未来中呈现出一种悬置状态，尽管他不断地用细节去强调时间概念，像《阿飞正传》里那个著名的开场、《重庆森林》里对日期的反复诉说和《东邪西毒》里经常会在事件开头指出节气，但他讲述的这些故事并没有特别的时间背景，它们可能每天都会发生在这个城市的角落里，它们只是从城市生活中抽离出来的标本。如果你仔细看过《重庆森林》，你就会发现两个故事的某些细节其实是互相交错的，王家卫用这种捉迷藏式的游戏来造成一种共时性的效果，既消解了传统叙事的线性时间观念又凸现了当代都市生活的偶然和无序，从而形成了一种存在主义式的精神意蕴，而王家卫在空间上的运用更是与其时间相得益彰，如果你看了王家卫的作品而感动的话，那绝不是由于整体世界的印象所引发的，而是因为细节、片断以及絮语化的主观独白所唤起的气氛能让你产生心领神会的共鸣使然
