Advantages of TC Methods

When it comes to SAR orthorectification, which of these following algorithms has a higher priority to be used? Any significant advantage one has over another?

SAR-Simulation Terrain Correction vs. Doppler Range Terrain Correction vs SAR simulation

For most cases use the Range Doppler Terrain Correction. It’s efficient and accurate according to your orbits and DEM. In cases where the orbit data may not be accurate enough in particular with older missions then you may need the SAR Simulation Terrain Correction.
