The two-color focal plane array detects a target or image a target in the traviolet (UV) and infrared (IR) simultaneously. The system is a correlation, contrast or moving target tracker with very good countermeasure capability against a ground, sea, or airborne target. The tracker/seeker can be an all solid state no-moving parts configuration with the two focal plane devices of detectors aligned in their layer so as to be at an effectively cofocal.
