Angle-gather time migration

Examples

We created some simple synthetic models with constant velocity backgrounds to test our angle-gather migration method. One model is a simple dome (Figure 4). The other has a series of flat reflectors of various dips (Figure 5). Both of these figures also show the corresponding data that will be generated by Kirchhoff methods for zero and far offsets.
