It outlines the acceptable range of coherence values for the averaging window. Based on these findings, the paper also introduces a method for enhancing map coherence. The SAR interferogram calculation using this enhanced method is carried out. The paper demonstrates an improvement in accuracy compared to traditional techniques.
