Abstract:

The smoothing of aerial gravimeter records is investigated theoretically using the theory of stationary stochastic processes time series. Two methods of optimum filtering are considered first, least-squares filtering, due to Norbert Wiener, where the r.m.s. error is minimized absolutely and second, equal-spectrum filtering, where the r.m.s. error is minimized subject to the condition of least distortion as expressed by preservation of spectrum. The equal-spectrum method seems to be more appropriate for aerial gravimetry because of the high noise level and has a considerable practical advantage. Emphasis is on digital computation, for which practical formulas are given analog computation by means of electric networks is outlined. Author
