Subject: | GRW/WACR/M1 - Coherence Filter Contamination |
DataStreams: | grwwacrM1.b1 |
Description: | The coherence filter (software) that was added to the WACR under BCR-01500 was causing occasional contamination to WACR data. This was exhibited in the first 2000 m of range by streaking in the data over a period of time. It didn't occur often and when it did, it is quite obvious looking at the plots. On 4/2/2010 at 12:00 UTC, the coherence filter was modified to preclude working on signals with a SNR greater than 60 dB. The vendor thinks this will solve the problem. |
Suggestions: | Spectra data can probably be "easily" filtered to remove this artifact. Regenerating the Doppler moments from the filtered spectra will need to be done. |
