Description: | The NSA at Barrow was experiencing technical difficulties related to hardware problems. Water was found in a waveguide, which may adveresly impact sensitivity. An up-down converter problem was also found. This problem may also impact sensitivity. The quality of the radar calibration during this period is unknown, but will be determined at a later date. |

Description: | From 3-July 2001 to 26-July 2001, the NSA MMCR calibration for the two coded pulse modes is incorrect. The values of reflectivity computed by the radars autocalibration software are wrong because they use the wrong radar constant. The correct radar constants are: 8-bit coded mode RC=16.344 and for the 32-bit coded RC=7.313. The only impact of the incorrect radar constants should be reflectivity value |
