Dear Sirs: I have some questions on X-SAR image. If you help me ou, I will appreciate you very much. I need to get sigma nought image of X-SAR image which was taken during the SIR-C/X-SAR campaign. Could you let me know if ENVI can handle this? If not, can you recommend what I can do for this? Thank you for your time. I am looking forward to hearing from you soon. Best Wishes,
