Cross Correlation Analysis to Determine the Environmental Parameters Correlated with Electro-Optical System Performance.

摘要

Sensor effectiveness in operational environments often depends on several environmental parameters, not only individually but, because they are often at least partly correlated, on the peculiar real world combinations in which they occur. While the statistical occurrence of various parameter combinations can be derived from weather observation records, correlated parameter statistics are not generally available, and, in any case, have limited utility because they do not directly transform to system performance characteristics. In this study, figures of merit associated with Electro-Optical (EO) sensor performance were calculated for individual synoptic conditions reported over a three year period of record for locations of interest. Using the resulting data base, which included the calculated figures of merit, as well as the weather parameters upon which they were based, performance statistics were developed and cross correlations performed; several potentially useful parameter correlations were found.
