DIRECTED INFRA-RED COUNTERMEASURE SYSTEM

摘要

A tracking sensor for a directed infra-red countermeasure (DIRCM) system, the sensor comprising: a first set of image elements in a inner region of the sensor and each having or operable to monitor respective first fields of view; and a second set of image elements in an outer region of the sensor and each having or operable to monitor respective second fields of view. The first fields of view are smaller than the second fields of view or the image elements of the first set provide higher resolution than the image elements of the second set.
