Wavelet domain SAR raw data compression algorithm;

SAR raw data compression by using lifting wavelet transform and block adaptive quantization is studied based on the known results,that a block normalized SAR raw signal is a Gaussian stationary process and the feature of wavelet transform can eliminate the signal correlation for its multi-resolution decomposition.

A raw data acquisition system for detecting ocean wind-fields

A new 3-D image reconstruction method,presented in this paper,is to use the helical scan continuity,sufficient condition of image reconstruction and the raw data from a few helical scan cycles to reconstruct,by a direct interpolation algorithm,2-D images and then 3-D images.

The hydrometry original data processing system has been developed to resolve problems of tedious and time-consuming original data calculation and arrangement.

After college utilization of computerized accounting,the quality of output information depends mainly on the data collected and input,so it is essential to get high quality original data.

To achieve the original data of high quality is very important in the computerized accounting system.
