| Description: | 1. The sign of Doppler velocity of Ka/WSACR has been changed. The sign of Doppler velocity
of WSACR was inconsistent with KAZR and KaSACR from December 14, 2012 to January 15,
2013. Before December 14, 2012, Doppler velocity signs from both W and Ka SACRs were
inconsistent with KAZR. After February 1, 2013, the signs from SACRs are consistent with KAZR.
2. Ka/WSACR spectra have significant leakage, but something is clearly wrong with the
KaSACR (see attached file). The WSACR leakage occurs only at higher SNR, but that when it
occurs the first side lobe is only ~30 dB down, much less that the ~50 dB for the KAZR.
3. We could not find Doppler spectra data from Ka and W SACRs for the same time periods
even though moments files for the vertical pointing scans for both Ka and W SACRs exist.
There are synchronized signals in Doppler spectram in vertical potinting data from
Ka/WSACR. |
