Simple and effective method to improve the signal-to-noise ratio of compressive imaging

This Letter presents a simple and effective method to improve the signal-to-noise ratio（SNR） of compressing imaging. The main principles of the proposed method are the correlation of the image signals and the randomness of the noise. Multiple low SNR images are reconstructed firstly by the compressed sensing reconstruction algorithm, and then two-dimensional time delay integration technology is adopted to improve the SNR. Results show that the proposed method can improve the SNR performance efficiently and it is easy to apply the a lgorithm to the real project.

近海四分量地震资料解释及应用

莺歌海盆地的岩石弹性物性的变化是有规律的。气层的纵横波速度比、泊松比远远低于水层和泥岩层。研究并开发了一系列的四分量地震资料解释方法(如烃类检测方法等)。总结出了一套适合于中国近海四分量地震勘探资料解释和应用的流程。四分量地震技术在改善莺歌海盆地的构造成像、浅层气层检测及岩石各向异性(裂隙预测)方面的效果是很好的。用泊松比预测了乐东8-1等构造中深层的岩性物性和含气性。乐东8-1、乐东22-1构造中深层的勘探前景是比较好的。
