Subject:
SGP/CSAPR/I7 - PhiDp Decreasing with Range
DataStreams:sgpcsaprrhiI7.00
Description:
The differential phase is decreasing with range during this period, it should be 
increasing with range.  There are also periods of obviously bad PhiDp caused by a problem with the 
digital receiver software.
Measurements:sgpcsaprrhiI7.00:
  • Unfiltered differential propagation phase shift(dp_phase_shift_unf)
  • Unfiltered specific differential phase(diff_phase_unf)
  • Differential propagation phase shift(dp_phase_shift)
  • Specific differential phase, clutter filtered(diff_phase)
