To plot processed radar data use dataPlotter.m - change input folder path for radar and gps files first.

Radar File:
File Naming Convention: FL05_1us_Ch2_20140719_150329_2_1D_SAR.mat
Refers to 1D SAR processed data for Flight 5 using 1 us wide pulse from Channel 2 of the Deep Ice Radar; Flight date is July 19, 2014 and data start time is 15:03:29. 
Each mat file consists for following radar parameters/data:
The rows of 2D data are referenced to radar sampling time (fast time) and columns are to radar echotime (slow time);
ApertureSize - Aperture size used to migrate each line
CG - Radar Complex Image Data
FlightElev - Radar Elevation, WGS-84, m
Lat - Latitude Position of Radar, deg +/-
Lon - Latitude Position of Radar, deg +/-
PlaneHeight - Radar Height above the Surface, m
SurfElev - Surface Elevation, WGS-84, m
TWT - Sample Time, s
VertScale - Range, m
ampfactor - Amplification factor between two pulse types
breakind - sample number for radar transmission
c_air - velocity of light in air/space, m/s
c_ice - velocity of light in ice, m/s
dx - Along track resolution, m
dy_air - Range resolution in air, m
dy_ice - Range resolution in ice, m
echoTimeUTC - UTC time of radar echo, seconds since 00-Jan-00
f - Sampling frequency, Hz 
h - Mean plane height for the file, m
n - refractive index
samp_int - radar sampling interval, s
stitchind - range index for stitching two pulses - not used
surfind - range index for surface

GPS File: glnd3_ft05_200hz_gps_v1.mat - 200 Hz Navigation data WGS-84, ENU
Alt - Elevation, m
Heading - Flight heading, deg
Lat - Latitude, deg +/-
Lon - Longitude, deg +/-
Pitch - Aircarft Pitch Angle, deg
