Abstract :
This work presents an improved InSAR phase unwrapping (PU) method based on a combination of a particle filter, a region growing technique and a matrix pencil based local slope estimator. The better performance of this new solution when compared against some representative traditional methods and the previous particle filter PU approaches is justified and illustrated with results obtained from synthetic and real data.
