System ID:
00
Number of gates: 100
Range gate length (m):
30.0
Gate length (pts): 10
Pulses/ray: 15000
No. of rays in file: 1
Scan type:
Stare
Focus range: 500
Start time: 20140521 12:48:45.53
Resolution (m/s): 0.0382
Altitude of measurement (center of gate) = (range gate + 0.5) * Gate length
Data line 1: Decimal time (hours) Azimuth (degrees) Elevation (degrees) Pitch (degrees) Roll (degrees)
f9.6,1x,f6.2,1x,f6.2
Data line 2: Range Gate Doppler (m/s) Intensity (SNR + 1) Beta (m-1 sr-1)
i3,1x,f6.4,1x,f8.6,1x,e12.6 - repeat for no. gates
