为了提高信噪比,我们曾应用过各种类型的组合系统,但到目前为止,对组合法的研究还是很不够的。 本文讨论了不同类型组合系统的相关响应,给出了组合系统统计效应更一般的表达式,把表达式建立在严格的理论基础上。它适用于任意类型的组合系统,也适用于水平迭加、迭加偏移等具有动校正的非线性组合系统。通过组合参数的选择,进行弱相关接收或独立接收以提高统计效应,降低相关效应,这是增大信噪比,提高时问剖面可靠性的重要方法。
In order to improve the signal-to-noise ratio, we have used various types of composite systems, but so far, the study of combinatorial methods is still not enough. In this paper, the relative responses of different types of systems are discussed. The more general expressions of the statistical effects of the systems are given. The expressions are based on a rigorous theoretical basis. It applies to any type of combination system, also applies to the level of superposition, superposition of the offset with the dynamic correction of non-linear combination system. Through the combination of parameter selection, weak correlation or independent reception to improve the statistical effects and reduce the correlation effect, which is to increase the signal to noise ratio, an important method to improve the reliability of the time section.
