Two color temporally correlated infrared background measurements

The use of high speed multicolor imaging sensors provides a valuable tool for characterizing both the signatures of missiles as well as clutter. Over 114 flight hours worth of collections were made of difficult to characterize clutter. This additional data can be utilized to develop and improve missile warning algorithms for better false alarm rates. These analyses show that although-a two color staring system could have multiple advantages over a single color system in false alarm rejection, the clutter rejection capabilities can be limited by the relatively low inter-band correlations between the red and blue bands.
