f Determination of the source siganture of a dynamite source using the source scaling law

In land seismic data acquisition using a dynamite source it is normally impossible to measure the source signature. In most geologies the measurement is contaminated by scattered energy, and it is impossible to separate the incident field from the scattered field. However, in any serious attempt to invert the seismic data using wave propagation theory, it is essential to know the signature at the source; for the dynamite source this signature is the volume injection function.
