Flat earth removal and baseline estimation based on orbit parameters using Radarsat-2 image

Primarily the article briefly introduces the basic concept of the flat earth removal and baseline estimation, and mainly introduces the method of flat earth removal and baseline estimation based on orbit parameters using Radarsat-2 image, in detail represents the processing of flat earth removal based on orbit parameters. By removing the flat earth phase of the interferogram and analyzing the result of flat earth removal, the accuracy of generated digital elevation model and surface deformation, it shows that the method is effective, thanks to the highly precise orbit parameters. Meanwhile, the baseline estimation can be operated, which improves the efficiency.
