Accelerograph calibration and accelerogram correction

Earthquake Engineering & Structural Dynamics, 1973
AbstractWhen measured earthquake accelerations are used as a basis for structural design, then acceleration errors of a few per cent are usually acceptable. However a number of tasks in structural design, and in earthquake engineering research, require measured accelerations with errors limited to a few parts per thousand.

HEAD 1.0: A Unified HEllenic Accelerogram Database

Seismological Research Letters, 2004
During the past thirty years various accelerogram data sets recorded by “free field” strong-motion stations in Greece have been compiled by two institutes that are in charge of running national strong-motion networks. These data sets have been of limited potential use for research because of nonstandard processing, nonhomogeneous earthquake parameters ...

Inferring Critical Slip-Weakening Distance from Near-Fault Accelerogram of the 2014 Mw 6.2 Ludian Earthquake

Seismological Research Letters, 2021
To better assess potential earthquake hazards requires a better understanding of fault friction and rupture dynamics. Critical slip-weakening distance (Dc) as one of the key friction parameters, however, is hard to determine on natural faults.

An Adaptive Spectrogram and Accelerogram Algorithm for Electronic Warfare Applications

Radar, 2020
This paper presents a novel adaptive approach to spectrogram and accelerogram calculation based on the signal chirp rate (CR). Such a method may be useful in electronic intelligence (ELINT), electronic warfare (EW) and electronic reconnaissance (ER) or ...

Radar Signal Parameters Estimation Using Phase Accelerogram in the Time-Frequency Domain

IEEE Sensors Journal, 2019
Radar signal parameter estimation, in the context of the reconstruction of the received signal in a passive radar utilizing other radars as a source of illumination, is one of the fundamental steps in the signal processing chain in such a device.

Noise in Earthquake Accelerograms

Journal of the Engineering Mechanics Division, 1982
The amplitudes of processing and digitization noise in strong motion earthquake accelerograms are reviewed for hand and automatic digitization. By finding the period bands for which the signal-to-noise ratio in digitized accelerograms is greater than one, dependence of cut-off periods for accelerogram data processing is presented for amplitude scaling ...
