In order to meet the needs of operational production products, especially for the production of LuTan-1 (LT-1) satellite data products, the Land Satellite Remote Sensing Application Center (LASAC) has developed the LandSAR software. The software, an operational application based on the Model-View-Controller (MVC) design pattern, maintains a low coupling between the interface module and the algorithm module while retaining a high running efficiency. It supports interferometric processing from SLC data to terrain or deformation products and optimizes processing process for LT-1 data. The software has now begun to be used for large-scale data production. In this paper, the code development and management methods of the software will be introduced, and the LT-1 deformation products produced by LandSAR will be presented at the end.
