Artificial seismic survey method using seismic reflected waves for marine geological survey. Measurement principle In this type of method, the physical model of seismic wave propagation in the medium is shown in Figure 1. The elastic wave excited from the source O is projected onto the reflection interface to generate a reflected wave, provided that the incident angle is equal to the reflection angle . To form a reflective interface, it is necessary to have the condition that the reflection coefficient on the interface R is not equal to zero when the elastic wave is incident perpendicularly.
