Integrating accelerometer and velocity meter records

SummaryEssentially, the message seems to be that greater than normal care needs to be exercised when using accelerometers whose signals are to be integrated, and some applications, such as at the end of the flexible L-shaped member in Fig. 4, should be avoided. The seismic correction eq (14) is normally applied to velocity-meter records to obtain the desired base velocity. However, if the base motion should suddenly cease, eq (13) should be used to avoid the extraneous straight-line effect.
