Field: Measurement (Instruments)
Classification: CPC G  Y | IPC G

Claim 2:
3. The method for automatically identifying an active source azimuth of a planet seismometer according to claim 2, wherein a calculation formula for the maximum amplitudes of components of a vibration signal in the R direction and in the T direction is:

Ari=max(|xhi*cos θai+yhi*sin θai|)

Ati=max(|xhi*sin θai+yhi*cos θai|)

wherein θai is an included angle between a direction of the i-th lander support leg and the N direction of the planet seismometer; Ari and Ati respectively represent the maximum amplitudes of components of a vibration signal in the R direction and in the T direction; i=1, 2, . . . N, N represents the number of the lander support legs.
