Efficient Estimation Techniques for Integrated Gravity Data Processing.
Abstract
A mathematical technique is developed for the combined use of various types of gravimetric data in the estimation of such gravity quantities as the disturbance potential and the gravity disturbance vector. Modern frequency domain techniques are introduced which substantially reduce the computer processing requirements associated with least-squares gravity quantity estimation. This approach represents an extension of existing least-squares methodology based on the use of self-consistent statistical gravity models. Analysis, supported by a numerical study, shows the equivalence of the estimates produced by the conventional space-domain methods and the new frequency-domain methods. Numerical simulations demonstrate the performance of the new technique for gravity surveys involving both single and multiple data types.
