Dear Sir,

Can we generate DEM of 1:250000 resolution from any available satellite for the Indian region?

This topic has already widely been discussed in this forum. Please have a look at these tutorials on DEM generation with different sensors and modes:

• DEM generation with Sentinel-1 - Workflow and challenges
• Sentinel-1 Stripmap Interferometry
• Interferometry Tutorial with Radarsat-2

Furthoremore, the discussions in here are crucial for undestanding the challenges:

• The Order of DEM Creating Steps
• Some explanations about concepts of fringes of interferogram and coherence
