摘要： Method for performing simultaneous encoded-source inversion of geophysical data to estimate parameters of a physical property model (41), especially adapted for surveys without fixed-receiver acquisition geometry, such as marine seismic surveys with moving source and receivers. The encoding functions (32) used on the sources to generate one or more simultaneous encoded-source gathers of data (35), as well as to simulate the same (34), are orthogonal or pseudo-orthogonal with respect to cross-correlation. In addition, receivers are also encoded, with the receiver encoding being designed to make a given receiver less sensitive to sources to which it was not listening during the survey (38). The encoding functions may be temporal bandpass filters differing one from another by central frequency, phase, or both. Efficiency of the method may be further improved by grouping several sources into a super-source, grouping the corresponding gathers into a super-gather, and then applying the above encoding strategy.

摘要翻译： 用于执行地球物理数据的同时编码源反演以估计物理性质模型（41）的参数的方法，特别适用于没有固定接收机采集几何的勘测，例如具有移动源和接收机的海洋地震勘测。 用于产生一个或多个同时编码的数据源集合（35）的源的编码功能（32）以及模拟相同的编码功能（34）在互相关方面是正交的或伪正交的。 另外，接收机也被编码，其中接收机编码被设计成使得给定的接收机在调查期间对其不倾听的源较不敏感（38）。 编码功能可以是通过中心频率，相位或两者彼此不同的时间带通滤波器。 可以通过将多个源分组成超级源，将相应的聚类分组成超级聚集，然后应用上述编码策略，可以进一步提高该方法的效率。
