Abstract
Different aspects of the reflectivity method are illustrated for the case of SH-wave propagation in a layered half-space. Starting with the original form of the reflectivity method, the combination with generalized ray theory is described which allows calculations of many interesting seismic phases, such as surface reflections and surface multiples, for only little additional computing time. Then the calculation of complete seismograms is described, first with wave-number integrals whose integrands have little or nothing to do with reflectivities, and second with integrands consisting mainly of the reflectivities of different parts of the layered medium. Each case is illustrated with an example of theoretical seismograms. Finally, a few remarks are made on aliasing in the time domain, on fast Hankel transforms and on causal absorption with frequency-dependent Q-factor.
