Estimate and Remove Linear Phase Ramps from Differential Interferograms.

Estimate and Remove a Linear Phase Ramp from Differential Interferograms.

Estimate and remove the contribution of a Linear Ramp to the Wrapped Phase of the considered Differential InSAR Interferograms.

Scripts:

1. remove_phase_ramp.py - Find the Phase Ramp optimal parameters employing a Grid Search approach. A first guess of the ramp parameters - e.g. number of cycles along columns and rows - must be provided by the user.
2. remove_phase_ramp_fft.py - Estimate the Linear Phase Ramp in the Frequency Domain as the maximum value of the Power Spectrum of the Signal.

Install Python Dependencies:

>> pip install -r requirements.txt

PYTHON DEPENDENCIES:

• numpy: The fundamental package for scientific computing with Python
• rasterio: access to geospatial raster data
• matplotlib: Library for creating static, animated, and interactive visualizations in Python.
