Abstract

See full text

A method for automatically identifying an active source azimuth of a planet seismometer, comprising: intercepting a three-channel original time sequence in a duration before and after an active source first arrival signal of each support leg received by a planet seismometer in turn; converting the three-channel original time sequence to a horizontal plane based on a pitch angle and a roll angle of the planet seismometer after being deployed to a surface of a planet; converting a time sequence of the horizontal plane to RTZ coordinates and calculating the maximum amplitudes of components of a vibration signal; constructing a target function based on the maximum amplitudes of components of a vibration signal, and scanning an azimuth of the planet seismometer at preset angle intervals, wherein when the target function reaches the minimum, the corresponding azimuth of the planet seismometer is the optimal estimation.
