NSA/MPL/C1 - Detector Failure

Beginning 12/25, the signal return displayed serious aliasing, reflection, or ringing of 
the detector, with a highly repetitive pattern repeating six or more times within the 
lowest 15 km.  On 01/02, the detector became very difficult to put into any type of operating 
condition. When it did operate, the "aliased" signal pattern was still present.

The detector was replaced.
