Sample Analysis

At White Sands, NM, the statistical characterization of the rms path length (phase) fluctuations is the primary data product of interest in determining the link margin performance of a arrayed communications system. Below is the Cummulative Distribution Function (CDF) of the rms path length, as measured at White Sands, NM, for the year of 2009/2010, indicating the 90% statistically expected value.

From this information, the expected performance of an antenna array at White Sands, NM, can be derived.
