This story unveils the hypocrisy of religion and scoffs at the conventional social principle. Affected by the deep-rooted racial discrimination, Huck pays little respect to the black slaves as other white people do at first. After embarking on the raft with Jim together, he has got the chance to know more about what the black slave truly is. He never stops struggling inside, and eventually Jim's kindness and loyalty helps Huck to waken humanity in his heart and defeat his moral conflict. Therefore through the deepened analysis of the plot and the author, the reasons for the change of Huck's morality can boil down to social conventions, Huck's complicated character, and moreover the democratic ideal of Twain.展开更多

Eliot's views on morality and rich life experiences are also drawing people's attention. The Mill on the Floss is Eliot's early works,which describes the heroine Maggie's short life experiences. She's brave enough to struggle for the outer strength. And from Maggie's behaviors, we can realize the standard of Eliot's views on morality. George Eliot is a faithful believer in the importance of morality in society. She acted by high moral standards in her own life and developed her moral ideas in her books.Eliot's moral ideas will be of great help in studying Eliot's works.展开更多

The echo data are captured by the missile-borne detector in the target regions;thereby the azimuth angulation accuracy at the same distance dimension is improved dynamically. Thus, azimuth information of the targets in the detection area may be obtained accurately. The proposed imaging algorithm breaks through the conventional misconception of merely using azimuth discrimination curves under ideal conditions during monopulse angulation. The real-time echo data from the target region are used to perform error correction for this discrimination curve, and finally the accuracy of the azimuth angulation may reach the optimum at the same distance dimension. A series of experiments demonstrate the validity, reliability and high performance of the proposed imaging algorithm. Azimuth angulation accuracy may reach ten times that of the detection beam width. Meanwhile, the running time of this algorithm satisfies the requirements of missile-borne platforms.展开更多

Analysis of the Doppler property in this paper indicates the feasibility of Bistatic Forward-Looking (BFL) SAR imaging. Considering the different Doppler property determined by the two platforms in BFL SAR, a new 2-D point target spectrum is derived in our study. Based on the spectrum, an imaging method is chosen for the configuration, and the point target simulation validates the analysis.展开更多

And the nonlinearity is not just the slight deviation from the linear part, but exhibits evident nonlinear departure in the RCM trajectory. If the RCM is not properly corrected, nonlinear image distortions would occur. Based on the RCM model, a modified two-step RCM compensation (RCMC) method for SA-FBSAR is proposed. In this method, firstly the azimuth-dependent RCM is compensated by the scaling Fourier transform and the phase multi- plication. And then the range-dependent RCM is removed through interpolation. The effectiveness of the proposed RCMC method is verified by the simulation results of both point scatterers and area targets.展开更多

In this paper, the authors introduce the detection of cavities under the railway substructure by using forward-looking ground penetrating radar (FLGPR). Main advantages of FLGPR are that such a system can illuminate a large area and can stand off a long distance over its down-looking counterpart. Two methods, frequency wave-number (F-W) synthetic aperture imaging (SAI) and beam-forming by delay and sum (DAS), are applied to process the collected data. Analysis and measuring show that the distinct radar image of the cavity beneath the substructure 1.2 m deep can be formed by these two methods.展开更多
