I'm new to SHARAD data and facing problems viewing the 2D radargrams. I have tried to open them with NASAView but it is only showing me columns of numbers. I tried to open the images with ENVI but even with different combinations of header offset, columns and rows, I am not able to view the radargrams. The browse images are there, but to analyze the images I need to view them in ENVI. Could someone please tell me how I might be able to visualize the radargrams in ENVI? (A sample header file for a SHARAD rdr file would also be very helpful).
