The orthogonal seismic trace set up on the concept of complex seismic trace is combined with the real seismic trace to form the imaginary part and the real part of the complex seismic trace.

It's very successful that complex seismic trace technique is applied in seismic data processing of petroleum geophysical prospecting,but in the domain of engineering geophysical prospecting the application is less,or the effect is not good.

Complex seismic trace technique has been used to obtain instantaneous parameters,which are of great importance to seismic data interpretation,reservoir description and lithologic information obtainment.

Based on complex seismic trace method,instantaneous polarization filter has been constructed.
