GTRI Naming Conventions

Filename: fxxxyyzz

xxx is a 3 digit number that uniquely identifies a parent file name that corresponds to a particular target elevation angle (antenna depression angle) with respect to the radar. Note several phase history blocks (files) have the same 3 digits as each elevation slice has been processed into several files corresponding to specific target aspects and transmit/receive polarization.

yy defines the transmit/receiver polarization (e.g., VV implies transmit vertical/receive vertical)

zz defines the phase block (file) number for a given elevation slice and polarization pair.

This number can be translated to a nominal target aspect using:

Target Aspect @ Aperture Center = zz*4.25 + 39.5*0.05 (Degrees)

Note: The indicated antenna depression angle in the pre-appended header is incorrect. The correct depression angle for each of the file sequences are listed below:
