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。

In The Big Typescript, this dichotomy is detailed in his analysis of the temporal, spatial and genitive expressions, resulting in the distinction between the unspeakable"memory-time"(Ged〓chtniszeit) and the speakable"physical time", and that between the unspeakable"visual space" and the speakable"Euclidean space", etc;(4) From another perspective, the destruction of the conception of the "phenomenological language"could also be seen as the logical consequence of the radicalization of the one and the same conception, since this destruction does reinforce rather than weaken RLF's original intention of distinguishing the physical system from what are given in phenomena by demonstrating the incompatibility between this intention itself and the insistence on the speakability of the phenomena, which gives birth to the illusion of the"phenomenological language";(5) Nevertheless, what the radical distinction between the sense-data and the physical language (as the unique possible language) implies, according to Wittgenstein, is not that the latter has nothing to do with the former, but that the association between the two does not follow the"original sample-copy"pattern but the"screen-presenting-filmoperation"pattern, which indicates that phenomenon itself can be aroused by or included in-rather than to be described by-the physical language/system;(6) Thus Wittgenstein leads us to depart from the obsolete ambition of representing the immediately given data perfectly for a new destination where a comprehensive "perspicuity" of the"grammar"should be required and where his later philosophy is coming into being.

在《大打字稿》中,这一二分法在他对于时间表达式、空间表达式与人称表达式的分析中得到了细化,并导致了他对于"记忆时间"与"物理时间"的区分,以及对于"视觉空间"与"欧几里得空间"的区分,等等;(4)从另一个视角来看,维氏对于"现象学语言"观念的拆解也可以被视为同一观念在被加以彻底化后所导出的必然后果,因为这一拆解工作实际上乃是加强了,而不是削弱了他在写作《略论逻辑形式》时就已怀有的信念,即:必须将物理系统严格地区分于在现象中被直接给予的东西。换言之,维氏在这一拆解工作中所做的,只不过就是暴露了这一信念本身与对于现象之"可说性"的坚执之间的固有矛盾罢了——而所谓"现象学语言"的幻相,亦正是导源于上述坚执;(5)然而,根据维氏的本意,感觉予料与物理语言之间巨大的逻辑差异却并不意味着后者与前者毫无关联,而只是意味着两者之间的关系并不遵循着所谓的"原本—摹本"模式,而遵循的乃是"屏幕呈现—胶片运作"模式。

After analyzing the merit and lack of 9I model, the main idea is proposed: to distill some basic topological relations from 9I model, of which the composite topological relations of complex objects are made up. In detail, the composite topological relationships between region and region, line and line, line and region are particularly discussed;(2)Analyze the characteristics and inner relations of cadastral features. According to the expressional model of complex topological relations, the author discovers the possible topological relations between parcels, parcel lines and parcel points. In addition, sum up the general topological relationship rules of cadastral data.(3) Then the topological relations model is extended to the spatio-temporal data. Time in cadastral database and change semantic are discussed. It's redefined that spatio-temporal topological relations is composed of time, location, status and event relation. Spatio-temporal topological relationships can be represented by extended 4I model. Taking cadastral parcels as example, there are different possible spatio-temporal topological relationships between parcels when they are extended, shrunken, split, merged or others. Thus, some deductions are drawn that, for example, if parcels have be coexisting for some time they are impossible to be overlapped. Furthermore, the parents of parcels alternated and their possible change types can be detected by their spatio-temporal topological relationships.(4) Before carrying out the experiment, the calculation method must be designed.
