Abstract
Forward modeling is performed to compute a response of a target structure, the forward modeling accounting for distortion of a reflected signal from a reflector in the target structure. Waveform inversion is performed using the response of the forward modeling.
Claims23
A method comprising:
- performing forward modeling to compute a response of a target structure that includes a reflector, the forward modeling using reflection information relating to the reflector and accounting for distortion of a reflected signal reflected from the reflector;
- and
- performing waveform inversion using the response of the forward modeling.
A system comprising:
- at least one processor to:
- compute a response of a target structure that includes partial and total reflections from a reflector in the target structure, wherein the response is computed using forward modeling that uses reflection information relating to the reflector;
- and
- based on the response, produce at least one parameter of the target structure using waveform inversion.
