Abstract
Phase unwrapping techniques are used in various applications, including 
Synthetic Aperture Radar (SAR) interferometry (InSAR). Deep learning 
methods have been recently proposed to tackle this problem. This work 
aims at explaining and evaluating the method proposed by Perera et al. 
in [A joint convolutional and spatial quad-directional LSTM network for 
phase unwrapping, ICASSP 2021]. Furthermore, we provide an online demo 
to simulate phase images and run them through the network. The network 
performance can be tested visually and through metrics such as the error 
standard deviation. The simulation can provide some out-of-distribution 
data, especially with the added atmospheric signal specific to the InSAR 
phase.
