Simulation Study of Airborne Gradiometry.

Abstract

A simulated field of gravity anomalies and second-order gradients is used to study the recovery of gravity anomalies at ground level from measurements at flight level. The spectral properties of gravimetric quantities simulated by an array of mass points are discussed for first and second order gradients and some rules are derived for generating such fields. To study the effect of observational errors, uncorrelated normally distributed errors and correlated errors from a stationary Markov sequence are used. Results agree well with estimates obtained in a previous accuracy study. Computations show that a fast operational program can be obtained by using a least-squares collocation procedure. The programs and a sample computation are part of the report. (Author)
