We discuss some aspects of the application of KMAH index in seismic data processing. The index can be useful when a priori information about a model of medium is available and the corresponding ray tracing can be done. It provides an opportunity to select areas in reflected seismic waves where the ray crosses a caustic. Such areas drastically reduce the quality of seismic sections, as well as worse the separation of signals related to target reflected horizons. Importance of using the KMAH index increases when structure of the model is known and it is required a detail study of the shape of seismic signal. Also, the index may be important in the solution of such tasks as extraction of signals, related to converted waves, for instance, the PSP-waves, from surface marine seismic data.
