Abstract
Apparatus (10) is provided for detecting an object (B) such as a xenon beacon on a missile (M) located within a defined field of view (FOV). The field of view is defined by an array (A) of pixels (P). A sensor (14) includes a detector (16) which repetitively scans the field of view to detect the presence of an object therein. The output of the sensor is converted for use in activating pixels in the array in response to the detection of the object. A processor (22), in response to the presence of the object, defines a pixel matrix within the array. This matrix includes the pixel for the detected object signature. The processor searches all the pixels within the matrix to identify a signature which matches a predetermined characteristic of the object. Identification of such a signature, helps particularly identify the object in the field of view. The processor then focuses on this pixel set, during subsequent scans, to track the object.
