Based on the paleoceanography spatial database, I replanned the paleoceanography databasesystem to figure out the security of the former system. I redivided the system functions anddesigned five function modules: right management module, data import and edit module,calculating year module by standard oxygen isotope curve, data analysis module and spatialanalysis module. The calculating year module adopted the method which compares the oxygenisotope stage borderlines. This method could acquire a more exact result and provide a friendlyinterface to make the consumer operate convenient.

Many new detection techniques are proposed, that include: To overcome the faults of cross-terms and short unambiguity range for the common Wigner-Ville Distribution , short-time Fourier transform and Gabor transform are applied to SAR moving target detection. To improve the detection performance of WVD in noise environment, a new technique based on the Cross-WVD is proposed. The application of fractional Fourier transform to chirp signal detection is analyzed and extended to SAR moving target detection. To eliminate the restriction of chirp-Fourier transform, a new modified definition is proposed and applied to SAR moving target detection. To detect multiple moving targets whose scattering intensities are different heavily, the CLEAN technique is combined with the above techniques and the ideal detection performance is achieved. At last, the whole dissertation is concluded.
