Calibration of the Broadband Sensor(STS-2) using the Step Method
스텝방법을 이용한 광대역지진계 센서(STS-2)의 검증
Abstract
A close examination of the step calibrations for STS-2 seismometers installed by KMA has been done to deduce the response parameters of those instrument including angular corner frequency, damping factor and coil constant factor. A non-linear least square inversion method has been apple iud to estimate these parameters. The estimated parameters coincide with the manufactory specification with less than 1% error. This method will be extended near- future to deduce the response parameters for SS-1 short period seismometer.
