对区域Ω上设定的震级和震源位置的可能事件,本文作了以下两点考虑:一、对于同一点上的事件,基于遥测台网垂直向地震计记录特征中 P 和 S 震相到时精度上的差异,从而引入了不同的测量标准误差σi。二、对不同位置不同震级的事件,根据子台的监测能力,应确定相应的子台组合。在这基础上,通过模拟地震波走时和奇异值分解方法,计算了估计震源参数精度的参量空间协方差矩阵,给出了震源参数误差理论值等值线图,用此方法讨论了该台网的定位能力。
For the possible events of the magnitude and source location set on the area Ω, this paper makes the following two considerations: 1. For events on the same point, based on the telemetry network vertical seismometer record characteristics of P and S seismic phase to Accuracy differences, which introduced a different measurement standard error σi. Second, different magnitudes of events at different locations, according to sub-station monitoring capabilities, should determine the appropriate sub-station combination. On this basis, the parameter space covariance matrix for estimating the parameters of seismic source was calculated by simulating the traveltime of seismic wave and the singular value decomposition method, and the contour of the theoretical value of source parameter error was given. Using this method, Positioning capabilities.
