基于小波域的图像压缩分组编码及其差错隐藏.(Image compression based on wavelet packet coding and error to hide.)

线性调频（LFM）脉冲压缩雷达仿真,脉冲压缩雷达能同时提高雷达的作用距离和距离分辨率。这种体制采用宽脉冲发射以提高发射的平均功率，保证足够大的作用距离；而接受时采用相应的脉冲压缩算法获得窄脉冲，以提高距离分辨率，较好的解决雷达作用距离与距离分辨率之间的矛盾。(Linear frequency modulation (LFM) pulse compression radar simulation, pulse compression radar while increasing the role of the radar range and range resolution. This system uses the width pulse emission in order to improve the average power emitted, to ensure a sufficiently large effective distance accepted when the corresponding pulse compression algorithm to obtain a narrower pulse, in order to improve the distance resolution, the better solution of the radar range and range resolution the contradiction between the rate.)
