Abstract
InSAR technology belongs to microwave remote sensing technology. Because of the wide application of InSAR technology, it is gradually popularized. Because of its high data processing and higher precision, so phase unwrapping directly affect the final digital elevation information. The phase unwrapping process in InSAR data processing has a great influence on the accuracy of the DEM, so it is a key step to improve the accuracy of phase unwrapping. Through the research and analysis of direction cosine and the branch method .This paper improves the results of phase unwrapping by combining the modified discrete cosine transform and the branch method. This experiment shows that the combining model can complement each other, which would be a better solution to filter out the speckle noise and maintain the image detail. It further proves the significance of InSAR technology and its great advantage and potential.
