Hi Ricardo,
To create a time-dependent seismic pulse in MATLAB with a moving source, follow these simplified steps:
1. Define the Seismic Pulse: Use a mathematical model like a Gaussian function to represent your seismic pulse. For example, a Gaussian pulse centered around a specific frequency.
2. Model the Source Movement: Represent the source's movement with a simple model, such as linear motion at a constant velocity. This gives you the source's position as a function of time.
3. Combine and Simulate: Calculate how the moving source affects the seismic pulse observed at a fixed point in space. This involves adjusting the pulse based on the distance between the moving source and the observation point, considering the speed of wave propagation.
- Calculate the distance from the source to the observer at each time step.
- Determine the time it takes for the seismic wave to travel from the source to the observer.
- Adjust the seismic pulse timing based on this travel time to simulate how the pulse is observed as the source moves.
4. Plot Results: Visualize the original and the observed seismic pulses to understand the impact of source movement.
