Subject:
MAO/DL/M1 - Banding artifacts in the SNR
DataStreams:maodlppiM1.b1, maodlfptM1.b1, maodlusrM1.b1, maodlrhi2M1.b1, maodlcal2M1.b1,
maodlcal1M1.b1
Description:
Time height displays of the intensity (SNR+1) and backscatter fields exhibit obvious 
horizontal banding artifacts. The bands are regions where the SNR goes negative - which isn't 
physical. The problem was caused by a glitch in the noise whitening procedure. The 
problem was fixed when the driver for the data acquisition card was updated.
The radial velocities do not exhibit obvious banding; however, they were likely affected 
in some way.
Suggestions: 
null
