On the basis of the analysis of the scores, the author makes conclusions about the characteristics of Schubert"s last three piano sonatas as followings: 1 The device of universal development in the movements composed in sonata form and rondo-sonata form is the most distinctive feature in the last three sonatas, which is also decisive in the trend of the whole movement and makes the developments relatively "still". 2 In the device of themes, the method of irregularity is preferred. However, By using extension, abbreviation, repetition and further repetition of periods, Schubert brings those themes to ingenious balance in both architectonics and aesthetics. 3 Chain method is applied in the connection of themes, in which the previous material is taken as basis and then modified together with the variations of new materials. By this way, the theme is continuously developed. 4 The principle of the dominant-subordinate is followed in Schubert"s three-key exposition, and the process of each key is extended.
本文在详尽分析乐谱的基础上,对最后三首奏鸣曲的主要创作特点进行了以下总结: 1、奏鸣曲式和奏鸣回旋曲式乐章中展开的普遍化是最后三首奏鸣曲最为显著的特点,它决定了整个乐章的走向,并使展开部具有相对"静止"的特点; 2、舒伯特的主题写作中更喜欢运用非方整性写法,并通过自身材料的延长、缩减和重复或者更高一级的段落重复使其达到了结构上和审美上的巧妙平衡; 3、舒伯特喜欢用链式的主题贯穿方式,音乐以之前的材料为依据,经过变化后再加入新的材料,用这种方式不间断地发展; 4、舒伯特的三调呈示部遵循从主到属的总体原则,并扩展了调性历程。

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。

First, it begins with the study of the centralized CFAR detection with multiple sensors. The non-CFAR problem is analyzed; the necessity for local CFAR processing is established. The effective local CFAR processing scheme is proposed, i.e. the local test statistic. The upper limit of the optimal performance is proved for the distributed CFAR detection based on LTS. Then, the new schemes based on LTS are analyzed in condition of signal pulse, and then the analysis is expanded to the case of multiple pulses. Next, the feedback mechanism is introduced. At last, the invariant test is used to reveal the essence of CFAR processing. It explains the necessity of local CFAR processing in the distributed CFAR detection at a higher level.

Ernest August Gutt has been engaged in this domain and made great achievements.A systematic research on Gutt"s translation theory clarifies some misunderstandings concerning this theory, disclosing its true nature and exploring its explanatory power to translation practice. Furthermore this thesis probes into the application of Gutt"s theory to literary translation, pointing out that Gutt fails to realize the important role that non-formal aesthetic markers, such as tone and feeling, play in transferring aesthetic values in literary translation, though he lays much emphasis on the transference of formal aesthetic markers. Attempts have been made to amend Gutt"s theory in respect of transferring aesthetic values of literary work by means of "non-formal aesthetic markers, with the aim of making it more suitable for literary translation between Chinese and English.
