reversal processing

This dissertation analyses the theory of time reversal array processing and its focusing character in frequency-and temporal-domain.

本文从频域和时域两个角度分析了时间反转镜阵处理原理及其时间压缩、能量聚焦的特性，并对阵处理增益进行了推导。

Referring to the characteristic of the television image, multi frame interfusion processing draws the motion information from the image in time series, constructs the restoration filter, and restores images by the reversal filtering in the frequency domain.

针对电视摄像的特点，多帧融合处理技术从图像时间序列中提取景物的运动信息，构造复原滤波器，通过频率域反转滤波方式复原模糊图像。
