ABSTRACT:
An infrared sensor for short range detection of aircraft wherein the sensor is designed to operate with the sun in the field of view yet still be able to track its target. The sensor operates on a spinning platform, wherein the spinning platform has precessional motion. The sensor has a first detector array for detecting the presence of the sun and other background clutter. The sensor further has a second detector array sensitive to radiation in a predetermined frequency band for tracking a specific target. The sensor has an objective lens to focus the radiation on the first and second detector arrays.
